2 Printing Tasks Overview This chapter presents basic printing tasks, such as: • • • • Selecting the output bin. Loading the trays. Printing on both sides of paper with the optional duplexer. Printing on special paper, such as letterhead and envelopes, (including automatically feeding envelopes with the optional envelope feeder). This chapter also introduces some advanced printing tasks, to help you take full advantage of the printer’s features.
Selecting the Output Bin The printer has two output locations: the rear output bin and the top output bin. To use the top output bin, be sure the rear output bin is closed. To use the rear output bin, open it. • • If paper coming out of the top output bin has problems, such as excessive curl, try printing to the rear output bin. To avoid paper jams, do not open or close the rear output bin while the printer is printing.
Printing to the Rear Output Bin The printer always prints to the rear output bin if it is open. Paper comes out of the printer face-up, with the last page on top. To open the rear output bin, grasp the handle at the top of the bin. Pull the bin down, and slide out the extension. Printing from Tray 1 to the rear output bin provides the straightest paper path.
Loading Tray 1 Note To avoid paper jams, do not load trays while the printer is printing. Tray 1 is a multi-purpose tray that holds a variety of paper, including up to 100 sheets of paper, 10 envelopes, or 20 index cards. The printer might pull paper from Tray 1 first. To change this, see page 63. For supported sizes of paper, see page A-3. 1 Open Tray 1. 2 Pull out the tray extension. 3 Set the side guides to the desired width. 4 Load Tray 1.
Loading Tray 2 (4050/4050 N) Tray 2 is a 500-sheet tray. The optional 500-sheet tray is adjusted differently (page 39). (Tray 2 and the optional 500-sheet tray can be interchanged in the printer.) Tray 2 adjusts for letter, A4, and legal sizes; these adjustments affect printer performance. Lock Note To avoid paper jams, do not load trays while the printer is printing. 1 Pull the tray completely out of the printer.
4 Load paper into the tray. For correct orientation, see page 46. 5 Make sure the paper is flat in the tray at all four corners and below the tabs on the guides. Slide the tray back into the printer. The printer automatically senses the size of paper loaded if the tray is adjusted correctly. To print by type and size of paper, see page 65.
Loading Trays 2 and 3 (4050 T/4050 TN) Trays 2 and 3 are 250-sheet trays. For supported sizes of paper, see page A-3. Choose A5 and B5 ISO as custom sizes in the printer driver for these trays (page 56). Note To avoid paper jams, do not load trays while the printer is printing. 1 Pull the tray completely out of the printer. 2 If the tray is not already set to the desired paper size, snap the left and right guides into place to match the width of the paper.
4 Load paper into the tray. 5 Make sure the paper is flat in the tray at all four corners and below the tabs on the guides. Gently slide the tray back into the printer. The printer senses the size of paper loaded if the tray is adjusted correctly. To print by type and size of paper, see page 65.
Loading the Optional 500-Sheet Tray The optional 500-sheet tray is Tray 3 for the HP LaserJet 4050/4050 N printers, or Tray 4 for the HP LaserJet 4050 T/ 4050 TN printers. This tray is adjusted differently than Tray 2 (page 35). Tray 2 and the optional 500-sheet tray can be interchanged in the printer. For supported sizes of paper, see page A-5. Note To avoid paper jams, do not load trays while the printer is printing. 1 Pull the tray completely out of the printer.
5 Make sure the paper is flat at all four corners and below the tabs on the guides. 6 Set the dial on the right side of the tray to match the paper size. Note Setting the dial adjusts the printer’s sensors. It does not adjust the guides inside the tray. 7 Gently slide the tray into the printer. To print by type and size of paper, see page 65.
Printing Both Sides of Paper (Optional Duplexer) The printer can automatically print on both sides of paper with an optional duplex printing accessory (duplexer). This is called duplexing. Note See the documentation included with the duplexer for complete installation and setup instructions. Duplexing might require additional memory (page C-1). The duplexer supports standard sizes from B5 JIS (7.2 by 10 inches or 182 by 257 mm) to legal (8.5 by 14 inches or 216 by 356 mm).
Guidelines for Printing Both Sides of Paper Caution Do not print on both sides of labels, transparencies, envelopes, or paper heavier than 28 lb (105 g/m2). Damage to the printer and paper jamming might result. WARNING! To avoid personal injury and damage to the printer, do not lift the printer with the duplexer installed. Before relocating the printer, separate the duplexer and optional trays from the printer. • • • • 42 You might need to configure the printer driver to recognize the duplexer.
Paper Orientation for Printing Both Sides of Paper The duplexer prints the second side of paper first, so paper such as letterhead and preprinted paper needs to be oriented as shown in Figure 9. Figure 9 Paper Orientation for Printing Both Sides of Paper For Tray 1, load the first side facing down and the top toward you. For all other trays, load the first side facing up and the top toward the printer.
Layout Options for Printing Both Sides of Paper The four print orientation options are shown below. These options can be selected from the printer driver or from the printer’s control panel (set BINDING from the Paper Handling Menu and ORIENTATION from the Printing Menu). 1. Long-edge portrait 2. Long-edge landscape* 3. Short-edge portrait* 4. Short-edge landscape Figure 10 Layout Options for Printing Both Sides of Paper 1. Long-edge portrait 2. Long-edge landscape 3. Short-edge portrait 4.
Printing Special Paper Special paper includes letterhead, prepunched (including 3-hole punched), envelopes, labels, transparencies, and custom-size paper. Printing Letterhead, Prepunched, or Preprinted Paper When printing letterhead, prepunched, or preprinted paper, it is important to correctly orient the paper. See the “Paper Orientation” section for instructions.
Paper Orientation For Tray 1, load paper with the side-to-be-printed facing up, and the top, short edge toward the printer. Figure 11 Paper Orientation for Tray 1 For all other trays, load paper with the side-to-be-printed facing down, and the top edge toward you.
Printing Envelopes With the optional envelope feeder, the printer will automatically feed up to 75 envelopes. To order an envelope feeder, see page 8. To print with the envelope feeder, see page 49. Many types of envelopes can be printed from Tray 1. (Up to 10 can be stacked in the tray.) Printing performance depends on the construction of the envelope. Always test a few sample envelopes before purchasing a large quantity. • • Set margins at least 0.6 inch (15 mm) from the edge of the envelope.
Loading Envelopes in Tray 1 1 Open Tray 1, but do not pull out the extension. (Envelopes feed best without the extension.) 2 Open the rear output bin and pull out the tray extension. (This reduces envelope curl and wrinkling.) 3 Load up to 10 envelopes in the center of Tray 1 with the side-to-be-printed facing up, and the postage-end toward the printer. Slide the envelopes into the printer as far as they will go without forcing them.
Feeding Envelopes Automatically (Optional Envelope Feeder) With the optional envelope feeder, the printer will automatically feed up to 75 envelopes. To print envelopes without an envelope feeder, see page 47. Note See the documentation included with the envelope feeder for complete installation and setup instructions. You might need to configure the printer driver to recognize the envelope feeder. See the printer software help for details.
Inserting and Removing the Envelope Feeder 1 Open Tray 1. 2 Open the access door on the right, front corner of the printer, inside Tray 1. 3 Remove the plastic cover from the printer. (Replace the cover when the envelope feeder is not attached.) 4 Insert the envelope feeder into the printer as far as it will go. (The connector on the top right side of the envelope feeder fits into the plug in the printer.) Pull gently on the envelope feeder to be sure that it is securely in place.
Loading Envelopes in the Envelope Feeder Note Print only on envelopes approved for use in the printer (page 47 and page A-11). 1 Fold down the tray extension. Lift the envelope weight. 2 Squeeze the release lever on the left envelope guide and slide the guides apart. 3 Load envelopes into the envelope feeder with the side-to-be-printed facing up, and the postage end toward the printer. Push the envelopes into the envelope feeder as far as they will go without forcing them.
4 Adjust the guides to touch the envelopes without bending them. Make sure the envelope feeder is not overfilled. 5 Lower the envelope weight onto the envelopes. Note Select the envelope size from the software application (if the setting is available), the printer driver, and the Paper Handling Menu in the printer’s control panel (page B-5). To print by type and size of paper, see page 65.
Printing Labels Use only labels recommended for use in laser printers. Make sure that labels meet the correct specifications (page A-3). Do: • • • Figure 14 EN Print a stack of 50 labels from Tray 1 or a stack of 50 to 100 labels from other trays. Load labels in Tray 1 with the side-to-be-printed facing up, and the top, short edge toward the printer. For orientation in other trays, see Figure 12 on page 46. Try opening the rear output bin (page 33) to prevent curl and other problems.
Do not: Caution Failure to follow these instructions can damage the printer. • • • • • 54 Do not load the trays to capacity because labels are heavier than paper. Do not use labels that are separating from the backing sheet, wrinkled, or damaged in any way. Do not use labels that have the backing sheet exposed. (Labels must cover the entire backing sheet with no exposed spaces.) Do not feed a sheet of labels through the printer more than once.
Printing Transparencies Use only transparencies recommended for use in laser printers. For transparency specifications, see page A-10. • • • • Figure 15 EN Load transparencies face up in Tray 1 with the top toward the printer. A stack of 50 to 100 transparencies can be printed from other trays. Because transparencies are heavier than paper, do not load the other trays to capacity. For orientation in other trays, see Figure 12 on page 46.
Printing Cards, Custom-Size, and Heavy Paper Custom-size paper can be printed from Tray 1 or the optional 500-sheet tray. For paper specifications, see page A-2. Note Choose A5 and B5 (ISO) as custom sizes in the printer driver for Tray 2 and Tray 3 (HP LaserJet 4050 T/4050 TN printers) and the optional 500-sheet tray. Settings for these sizes are marked in the tray, but custom settings must be selected in the software and from the printer’s control panel.
Guidelines for Printing Custom-Size Paper • • • Do not attempt to print on paper smaller than 3 inches (76 mm) wide or 5 inches (127 mm) long. Set page margins at least .17 inch (4.23 mm) away from the edges. Feed short-edge first. Setting Custom Paper Sizes When custom paper is loaded, size settings need to be selected from the software application (the preferred method), the printer driver, or from the printer’s control panel.
If the settings are not available from the software, set the custom paper size from the control panel: 1 2 3 4 5 From the Printing Menu set CONFIGURE CUSTOM PAPER=YES. From the Printing Menu, select inches or millimeters as the unit of measurement. From the Printing Menu, set the X dimension (the front edge of the paper) as shown in Figure 16. X can be 3 to 8.5 inches (76 to 216 mm). Set the Y dimension (the side edge of the paper) as shown in Figure 16. Y can be 5 to 14 inches (127 to 356 mm).
Advanced Printing Tasks This section will help you take full advantage of the printer’s features. These tasks are “advanced” because they require you to change settings from the printer’s control panel or the printer driver. Using Features in the Printer Driver When you print from a software application, many of the printer’s features are available from the printer driver. To access Windows printer drivers, see page 23. Note HP PCL 5e, PCL 6, PS, OS/2, UNIX and Macintosh drivers are slightly different.
RIP ONCE RIP ONCE allows the print job to be processed one time at the printer. The RIP ONCE capability creates an image of the page then saves a compressed image of the page into memory. RIP ONCE is enabled when a minimum of 16 MB of RAM or a hard disk is installed in the printer. Pages are printed by decompressing page images without pausing to process the print job again. The print job will print exactly the same every time because the compressed image is not dependent on any other printer data.
Different First Page Follow these instructions for printing a first page that is different from other pages in the print job. 1 For Windows, select “Use different paper for first page” in your printer driver. Choose Tray 1 (or Manual Feed) for the first page and one of the other trays for the remaining pages. Place the paper for the first page in Tray 1. (For manual feed, place paper in Tray 1 after the job is sent to the printer and the printer requests paper.
Printing Multiple Pages on One Sheet of Paper You can print more than one page on a single sheet of paper. This feature is available in some printer drivers, and provides a cost-effective way to print draft pages. To print more than one page on a sheet of paper, look for a Layout or Pages Per Sheet option in the printer driver. (This is sometimes called 2-up, 4-up, or n-up printing.
Customizing Tray 1 Operation Customize Tray 1 to fit your printing needs. The printer can be set to print from Tray 1 as long as it is loaded, or to print only from Tray 1 if the type of paper loaded is specifically requested. Set TRAY 1 MODE=FIRST or TRAY 1 MODE=CASSETTE from the Paper Handling Menu in the printer’s control panel. (Print speed might be slightly slower when printing from Tray 1 when TRAY 1 MODE=FIRST .
Manually Feeding Paper from Tray 1 The Manual Feed feature allows you to print on special paper from Tray 1, such as envelopes or letterhead. If Manual Feed is selected, the printer will print only from Tray 1. Select Manual Feed through the software or printer driver. Manual Feed can also be enabled from the Paper Handling Menu in the printer’s control panel. Note 64 When Manual Feed is selected, if TRAY 1 MODE=FIRST the printer automatically prints (if paper is in the tray).
Printing by Type and Size of Paper You can configure the printer to select paper by type (such as plain or letterhead) and size (such as letter or A4), as opposed to source (a paper tray). Benefits of Printing by Type and Size of Paper If you frequently use several different kinds of paper, once trays are set up correctly, you do not have to check which paper is loaded in each tray before you print. This is especially helpful when the printer is shared, and more than one person loads or removes paper.
4 Note From the software or printer driver, select the desired type and size of paper. The type and size settings can also be configured from HP Web JetAdmin and HP JetAdmin software for networked printers. See the printer driver help. To print by type and size, it might be necessary to unload or close Tray 1, or set TRAY 1 MODE=CASSETTE from the Paper Handling Menu in the printer’s control panel. For more information, see page 63.
Job Retention Features To use the job retention features listed below, you must install a hard disk in the printer and properly configure the drivers. Caution Make sure to identify your jobs in the printer driver before printing. Using default names may override previous jobs with the same default name or cause the job to be deleted. Quick Copying a Job The quick copy feature prints the requested number of copies of a job and stores a copy on the printer’s hard disk.
Deleting a Stored Quick Copy Job When a user sends a quick copy job, the printer overwrites any previous jobs with the same user and job name. If there is not a quick copy job already stored under the same user and job name and the printer needs additional space, the printer may delete other stored quick copy jobs starting with the oldest job. The default number of quick copy jobs that can be stored is 32. The number of quick copy jobs that can be stored is set from the control panel (see page B-18).
Proofing and Holding a Job The proof and hold feature provides a quick and easy way to print and proof one copy of a job and then print the additional copies. To permanently store the job and prevent the printer from deleting it when space is needed for something else, select the Stored Job option in the driver. Printing the Remaining Copies of a Held Job The user can print the remaining copies of a job held on the printer’s hard disk from the control panel.
Deleting a Held Job When a user sends a proof and hold job, the printer automatically deletes that user’s previous stored proof and hold job. If there is not a proof and hold job already stored for that job name and the printer needs additional space, the printer may delete other stored proof and hold jobs starting with the oldest one. Note If you turn the printer off and then back on, all quick copy, proof and hold, and private jobs are deleted.
Printing a Private Job The private printing feature lets a user specify that a job is not printed until that user releases it using a 4-digit personal identification number (PIN) through the printer’s control panel. The user specifies the PIN in the driver and it is sent to the printer as part of the print job. Specifying a Private Job To specify that a job is private from the driver, select the Private Job option and type a 4-digit PIN.
Deleting a Private Job A private job is automatically deleted from the printer’s hard disk after the user releases it for printing, unless the user selects the Stored Job option in the driver. Note If you turn the printer off and then back on, all quick copy, proof and hold, and private jobs are deleted. A private job can also be deleted from the printer’s control panel before it is ever printed.
Storing a Print Job The user can download a print job to the printer’s hard disk without printing it. The user can then print the job at any time through the printer’s control panel. For example, a user may want to download a personnel form, calendar, time sheet, or accounting form that other users can access and print. To store a print job permanently on the hard disk, select the Stored Job option in the driver when printing the job.
Deleting a Stored Job Jobs stored on the printer’s hard disk can be deleted from the control panel. 1 2 Note If you are using a Macintosh computer, the user name appears on the first line of the display and the job name appears on the second line of the display. After you have selected the desired user name using [Item], press [Value] until the desired job name appears. 3 4 5 74 Press [Menu] repeatedly until PRIVATE/STORED JOBS MENU appears. Press [Item] until the desired user name appears.
Printing with the Optional HP Fast InfraRed Receiver The HP Fast InfraRed Receiver enables wireless printing from any IRDA-compliant portable device (such as a laptop computer) to the HP LaserJet 4050, 4050 N, 4050 T, or 4050 TN printer. The printing connection is maintained by positioning the sending infrared (FIR) port within operating range. Note that the connection can be blocked by objects such as a hand, paper, direct sunlight, or any bright light shining into either FIR port.
If the connection is interrupted before your print job is complete, the HP Fast InfraRed Receiver status indicator turns off. You have up to 40 seconds to correct the interruption and continue the job. If the connection is resumed within this time, the status indicator lights up again. Note The connection is permanently broken if the sending port is moved out of operating range or if anything passing between the ports blocks transmission for more than 40 seconds.
3 Printer Maintenance Overview This chapter explains basic printer maintenance. EN • Managing the toner cartridge. • Cleaning the printer. • Performing routine maintenance.
Managing the Toner Cartridge HP Policy on Non-HP Toner Cartridges Hewlett-Packard Company cannot recommend use of non-HP toner cartridges, either new or remanufactured. Because they are not HP products, HP cannot influence their design or control their quality. To install a new HP toner cartridge and recycle the used cartridge, follow the instructions included in the toner cartridge box. Toner Cartridge Storage Do not remove the toner cartridge from its package until you are ready to use it.
Checking the Toner Level The user can find out how much toner is left in the toner cartridge by printing a configuration page (see page 134). The toner level is represented by the HP TonerGauge graphic on the configuration page. It shows approximately how much toner is left in the toner cartridge. Note After replacing a toner cartridge this value might become inaccurate if a user fails to select YES when the NEW TONER CARTRIDGE=NO message is displayed on the control panel.
Continue Printing When Toner Is Low When toner is low, the printer’s control panel displays the TONER LOW message. By default the printer will continue to print when the toner is low. The printer will continue to display TONER LOW until you replace the toner cartridge. If the you want to stop the printer when toner is low, change TONER LOW from the default of CONTINUE to STOP (see page B-16). When the toner is low, the printer will stop printing and STOP will be displayed. To resume printing, press [Go].
Redistributing the Toner When toner is low, faded or light areas might appear on a printed page. You might be able to temporarily improve print quality by redistributing the toner. The following procedure might allow you to finish the current print job before replacing the toner cartridge. 1 Open the top cover. 2 Remove the toner cartridge from the printer. WARNING! Avoid reaching too far into the printer.
3 Rotate the toner cartridge and gently shake it from side to side to redistribute the toner. Note If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. (Hot water sets toner into fabric.) 4 Reinsert the toner cartridge into the printer and close the top cover. If the print remains light, install a new toner cartridge. (Follow the instructions provided with the new toner cartridge.
Cleaning the Printer To maintain print quality, follow the cleaning procedure (on the following page) every time the toner cartridge is changed, or whenever print quality problems occur. As much as possible, keep the printer free from dust and debris. • • Caution Clean the outside of the printer with a slightly water-dampened cloth. Clean the inside with a dry, lint-free cloth. Do not use ammonia-based cleaners on or around the printer.
Cleaning the Printer Before beginning these steps, turn the printer off and unplug the power cord. 1 Open the top cover and remove the toner cartridge. WARNING! Avoid reaching too far into the printer. The adjacent fusing area might be hot! Caution To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. 2 Wipe any dust or dirt off the paper feed guides (shaded areas) with a dry, lint-free cloth.
4 Replace the toner cartridge, close the top cover, plug in the power cord, and turn the printer on. Note If the message NEW TONER CARTRIDGE = NO appears, ignore the message when removing the toner cartridge to clean the printer.
Using the Printer Cleaning Page If toner specks appear on the front or back side of your print jobs, follow the procedure below. From the printer’s control panel, do the following: 1 2 3 4 Note Press [Menu] until PRINT QUALITY MENU appears. Press [Item] until CREATE CLEANING PAGE appears. Press [Select] to create the cleaning page. Follow the instructions on the cleaning page to complete the cleaning process.
Performing Routine Maintenance Hewlett-Packard recommends that only HP-authorized service technicians service the printer. However, you should replace certain parts when the PERFORM PRINTER MAINTENANCE message appears on the printer’s control panel display. The maintenance message will appear every 200,000 pages. To check the number of pages the printer has printed, print a configuration page (see page 134). To order the printer maintenance kit, see page 9.

4 Problem Solving Overview This chapter will help you to troubleshoot and solve printer problems. Clear paper jams: Occasionally, paper can jam during printing. This section will help you to locate paper jams, properly clear them from the printer, and solve repeated paper jams. Understand printer messages: Many different messages can appear on the printer’s control panel display. Some messages tell the printer’s current status, such as INITIALIZING.
Clearing Paper Jams If the printer’s control panel displays a paper jam message, look for paper in the locations indicated in Figure 19, then see the procedure for clearing the paper jam. You might need to look for paper in other locations than indicated in the paper jam message. If the location of the paper jam is not obvious, look first in the top cover area underneath the toner cartridge. When clearing paper jams, be very careful not to tear the paper.
Paper jams can occur at the following locations: 2 1 3 4 6 5 Figure 19 Paper Jam Locations 1 2 3 4 5 6 Note EN Output areas (top and rear). Go to page 99. Top cover area. Go to page 96. Toner cartridge area. Go to page 98. Input tray area (optional envelope feeder). Go to page 94. Input tray areas. Go to page 92. Optional duplexer. Go to page 100. Loose toner might remain in the printer after a paper jam, but the toner should clear after a few sheets are printed.
Clearing Jams from the Input Tray Areas Note To remove paper from the Tray 1 area, slowly pull the paper out of the printer. For all other trays, follow the steps below. (See the next page for clearing envelope feeder jams.) 1 Slide the tray out of the printer, and remove any damaged paper from the tray. 2 If the edge of the paper is visible in the feed area, slowly pull the paper down and out of the printer. (Do not pull the paper straight out, or it will tear.
3 Before replacing the tray, make sure the paper is flat in the tray at all four corners and below the tabs on the guides. 4 Open and close the top cover to clear the paper jam message. If a paper jam message persists, there is still paper in the printer. Look for paper in another location (page 90).
Clearing Jams from the Optional Envelope Feeder 1 Remove any envelopes loaded in the envelope feeder. Lower the envelope weight and lift the tray extension up to close. 2 Press and hold the release button on the left side of the envelope feeder. Grasp both sides of the envelope feeder and carefully pull it out of the printer. 3 Slowly pull any envelopes out of the envelope feeder and the printer. 4 Insert the envelope feeder into the printer as far as it will go.
5 Open and close the top cover to clear the paper jam message. If a paper jam message persists, there is still paper in the printer. Look for paper in another location (page 90).
Clearing Jams from the Top Cover Area 1 Open the top cover and remove the toner cartridge. Caution To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes. 2 Use the green handle to lift the paper access plate. 3 Slowly pull the paper out of the printer. Do not tear the paper! Note Avoid spilling loose toner. Using a dry, lint-free cloth, clean any loose toner that might have fallen into the printer (page 83).
4 Replace the toner cartridge, and close the top cover. If a paper jam message persists, there is still paper in the printer. Look for paper in another location (page 90). Note If the message NEW TONER CARTRIDGE = NO appears, ignore the message when removing the toner cartridge to clear jams from the printer.
Clearing Jams from the Toner Cartridge Area 1 If you receive a paper jam message after using all paper jam removal procedures in the user’s guide, open the top cover and remove the toner cartridge. 2 Open Tray 1. 3 Use the green handle to lift the paper access plate and remove any jammed paper. 4 Remove the entrance cover to check for additional jammed paper. If paper is present, remove it. 5 Rotate the multipurpose paper guide to check for additional jammed paper. If paper is present, remove it.
Clearing Jams from the Output Areas Note If most of the paper is still inside the printer, it is best to remove it through the top cover area. Go to page 96. 1 Open the rear output bin. 2 Grasp both sides of the paper, and slowly pull the paper out of the printer. (There might be loose toner on the paper. Be careful not to spill it on yourself or into the printer.) Note If paper is difficult to remove, try opening the top cover all the way to release pressure on the paper. 3 Close the rear output bin.
Clearing Jams from the Optional Duplexer 1 Open the duplexer’s rear door. 2 Slowly pull any paper out of the duplexer. 3 Open and close the top cover to clear the paper jam message. 4 If the paper jam message persists, remove the duplexer by lifting it slightly and pulling it out of the printer. 5 From the rear of the printer, remove any paper on top of Tray 2. (You might need to reach inside the printer.) Continued on the next page.
6 Slowly pull any paper out of the duplexer. 7 Turn the duplexer over and remove any paper. 8 Insert the duplexer into the printer. 9 Open and close the top cover to clear the paper jam message. If a paper jam message persists, there is still paper in the printer. Look for paper in another location (page 90).
Solving Repeated Paper Jams If paper jams occur frequently, try the following: • Check all the paper jam locations. A piece of paper might be stuck somewhere in the printer. (See page 91.) • Check that paper is correctly loaded in the trays, that the trays are correctly adjusted for the loaded paper size, and that the trays are not overfilled. Make sure paper is under front and back tabs. (See the sections on loading paper, starting on page 34.

Supported Types of Paper The printer supports the following types of paper: • plain • letterhead • prepunched • bond • color • rough • preprinted • transparency • labels • recycled • card stock • user-defined (5 types) Guidelines for Using Paper For best results, use conventional 20 lb (75 g/m2) paper. Make sure the paper is of good quality, and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, voids, and curled or bent edges.
Note Do not use letterhead paper that is printed with low-temperature inks, such as those used in some types of thermography. Do not use raised letterhead. The printer uses heat and pressure to fuse toner to the paper. Make sure that any colored paper or preprinted forms use inks that are compatible with the printer’s temperature (400° F or 205° C for 0.1 second). Avoid using paper that has already been used in a printer or copier. (Do not print on both sides of envelopes, transparencies, or labels.
Paper Weight Equivalence Table Use this table to determine approximate equivalent points in weight specifications other than U.S. bond weight. For example, to determine the equivalent of 20 lb U.S. bond weight paper in U.S. cover weight, locate the bond weight (in row 3, second column) and scan across the row to the cover weight (in the fourth column). The equivalent is 28 lb. Shaded areas indicate a standard weight for that grade. U.S. Post Card* thickness (mm) U.S. Bond Weight (lb) U.S.
Labels Caution To avoid damaging the printer, use only labels recommended for use in laser printers. If you have problems printing labels, use Tray 1 and open the rear output bin. Never print on the same sheet of labels more than once. Label Construction When selecting labels, consider the quality of each component: • • • • Adhesives: The adhesive material should be stable at 400° F (205° C), the printer’s maximum temperature. Arrangement: Only use labels with no exposed backing between them.
Envelopes Envelope Construction Envelope construction is critical. Envelope fold lines can vary considerably, not only between manufacturers, but also within a box from the same manufacturer. Successful printing on envelopes depends upon the quality of the envelopes. When selecting envelopes, consider the following components: • • • • • Weight: The weight of the envelope paper should not exceed 28 lb (105 g/m2), or jamming may result.
Envelopes with Double-Side-Seams Double-side-seam construction has vertical seams at both ends of the envelope rather than diagonal seams. This style may be more likely to wrinkle. Be sure the seam extends all the way to the corner of the envelope as illustrated below.
Envelope Margins The following table gives typical address margins for a Commercial #10 or DL envelope. Note Type of Address Top Margin Left Margin Return Address 0.6 in (15 mm) 0.6 in (15 mm) Delivery Address 2 in (51 mm) 3.5 in (89 mm) For the best print quality, position margins no closer than 0.6 inch (15 millimeters) from the edges of the envelope. Envelope Storage Proper storage of envelopes helps contribute to good print quality. Envelopes should be stored flat.
Card Stock Construction • • • • Note Smoothness: 36-53 lb (135-199 g/m2) card stock should have a smoothness rating of 100-180 Sheffield. 16-36 lb (60-135 g/m2) card stock should have a smoothness rating of 100-250 Sheffield. Construction: Card stock should lie flat with less than 0.2 inch (5 millimeters) of curl. Condition: Make sure card stock is not wrinkled, nicked, or otherwise damaged. Sizes: Use only card stock within the following size ranges: • minimum: 3 by 5 inches (76 by 127 mm) • maximum: 8.

Serial Cable Specifications Serial communication is simply the transmission of data one bit at a time. With just one bit to transmit at a time, data can be transferred with a simple electrical circuit consisting of only two wires. In this fashion, an eight-bit byte is transmitted one bit at a time and the individual bits are reassembled into the original byte on the receiving end. Bit transmission occurs from the least significant bit to the most significant bit.
Serial Cable Specifications (Continued) Specification Description Hardware Flow Control (hardware handshaking) By definition, hardware handshaking is performed when two programs manipulate RS-232 control pins-DTR, DSR, RTS, and CTS to achieve a hardware-based form of flow control. In DTR/DSR handshaking, the sender asserts DTR (Data Terminal Ready) before sending the first character in a stream of data and waits for DSR (Data Set Ready) to be asserted in return.

Only reset the printer under the following circumstances: • You want to restore the printer’s default settings. • Communication between the printer and computer has been interrupted. • You are using both the serial and parallel I/O ports, and one of the ports is having problems.
Resets Menu Item Explanation RESET MEMORY This item clears the printer buffer and the active I/O input buffer, and makes the control panel defaults current. Resetting memory during a print job can result in data loss. RESTORE FACTORY SETTINGS This item performs a simple reset and restores most of the factory (default) settings. This item also clears the input buffer for the active I/O. Resetting memory during a print job can result in data loss.
C Printer Memory and Expansion Overview The printer has three dual in-line memory module (DIMM) slots for upgrading with: • More printer memory. DIMMs are available in 4, 8, 16, 32, and 64 • • • Note MB, for a maximum of 200 MB. Flash memory DIMMs, available in 2 and 4 MB. Unlike standard printer memory, flash DIMMs can be used to permanently store downloaded items in the printer, even when the printer is off. DIMM-based accessory fonts, macros, and patterns.
The printer has two enhanced input/output (EIO) slots for expanding the printer’s capabilities with: • A network card. • A mass storage device, such as a hard disk. For ordering information, see page 9. To find out how much memory is installed in the printer, or to find out what is installed in the EIO slots, print a configuration page (page 134).
Installing Memory Caution Static electricity can damage dual in-line memory modules (DIMMs). When handling DIMMs, either wear an antistatic wrist strap or frequently touch the surface of the DIMM’s antistatic package, then touch bare metal on the printer. If you have not already done so, print a configuration page to find out how much memory is installed in the printer before adding more memory (page 134). 1 Turn the printer off. Rotate the printer for access to its right side.
5 Remove the DIMM from the antistatic package. Hold the DIMM with fingers against the side edges and thumbs against the back edge. Align the notches on the DIMM with the DIMM slot. (Check that the locks on each side of the DIMM slot are open, or outward.) 6 Press the DIMM straight into the slot (press firmly). Make sure the locks on each side of the DIMM snap inward into place. (To remove a DIMM, the locks must be released.) 7 Close the DIMM access door and tighten the screw.
Checking Memory Installation Follow this procedure to verify that DIMMs are installed correctly: 1 Check that the printer’s control panel displays READY when the printer is turned on. If an error message appears, a DIMM might have been incorrectly installed. Check the printer messages (page 103). 2 Print a new configuration page (page 134). 3 Check the memory section on the configuration page and compare it to the configuration page printed before the DIMM installation.
Adjusting Memory Settings Resource Saving Resource Saving allows the printer to keep downloaded resources (permanent downloaded fonts, macros, or patterns) in memory when the printer language or resolution is changed. If you do not have an optional hard disk or flash DIMM for storing downloaded resources, you might want to change the amount of memory allocated to each language when downloading an unusually large number of fonts, or if the printer is in a shared environment.
I/O Buffering To allow the computer to continue working without waiting for the print job to finish queuing, the printer uses a portion of its memory (an I/O buffer) to hold jobs in progress. (If I/O buffering is off, no memory is reserved for this function.) In most cases, it is best to let the printer automatically reserve memory for I/O buffering. (For each megabyte of memory added to the printer, 100 kilobytes are reserved.
Installing EIO Cards/Mass Storage Turn off the printer before installing the EIO card or mass storage device. See Figure C-1 for orientation and location of the EIO card or optional mass storage device, such as a hard disk. Use HP Resource Manager to manage fonts on a mass storage device (page 25). For more information, see the printer software help. HP is constantly introducing new software tools for use with your printer and accessories. These tools are available from the Internet free of charge.
D Printer Commands F Overview Most software applications do not require you to enter printer commands. See your computer and software documentation to find the method for entering printer commands, if needed. PCL 5e PCL 5e printer commands tell the printer which tasks to perform or which fonts to use. This appendix provides a quick reference for users who are already familiar with PCL 5e command structure.
Understanding PCL 5e Printer Command Syntax Before using printer commands, compare these characters: Lowercase l: l Uppercase O: O Number one: 1 Number 0: 0 Many printer commands use the lowercase letter l (l) and the number one (1), or the uppercase letter O (O) and the number zero (0). These characters may not appear on your screen as shown here. You must use the exact character and case specified for PCL 5e printer commands.
Combining Escape Sequences Escape sequences may be combined into one escape sequence string. There are three important rules to follow when combining code: 1 2 3 The first two characters after the ? character (the parameterized and group characters, see Figure D-1) must be the same in all of the commands to be combined. When combining escape sequences, change the uppercase (termination) character in each individual escape sequence to lower case.
Entering Escape Characters Printer commands always begin with the escape character (?). The following table shows how the escape character can be entered from various DOS software applications.
Selecting PCL 5e Fonts PCL 5e printer commands for selecting fonts can be found on the PCL 5e Font List (page 136). A sample section is shown below. Notice the two variable boxes for symbol set and point size. These variables must be filled in or the printer will use defaults. For example, if you want a symbol set that contains line-draw characters, select the 10U (PC-8) or 12U (PC-850) symbol set. Other common symbol set codes are listed in the table on page D-8.

Environmental Product Stewardship Protecting the Environment Hewlett-Packard Company is committed to providing quality products in an environmentally-sound manner. The HP LaserJet printer has been designed with several attributes to minimize impacts on the environment. This HP LaserJet printer eliminates: • Ozone production The printer uses charging rollers in the electrophotographic process and therefore generates no appreciable ozone gas (O3).
• Toner consumption EconoMode uses significantly less toner, which might extend the life of the toner cartridge. • Paper use Depending on the type of software program in use, you can request that a number of pages of your document be printed on one sheet of paper. This N-up printing practice and the printer’s automatic duplexing feature, which provides two-sided printing, can reduce paper usage and the resulting demands on natural resources.
