These lights produce patterns that identify printer status. 1 2 3 4 Figure 2-3 Control-panel lights and buttons (HP LJ 1010 series printers) 1 ATTENTION light: Indicates that the print-cartridge door is open, print cartridge is missing, or other errors. 2 READY light: Indicates that the printer is ready to print.
Figure 2-4 Control-panel lights (HP LJ 1020 printer) 20 1 ATTENTION light: Indicates that the print-cartridge door is open, print cartridge is missing, and other errors. 2 READY light: Indicates that the printer is ready to print.
Media specifications The printers accept a variety of media. Properties such as weight, grain, and moisture content are important factors that affect printer performance and output quality. Media should conform to the guidelines in the User Guide. Media that does not meet HP guidelines might cause poor print quality, increased media jams, or premature wear on the printer, which might require printer repair.
Guidelines for using media HP LaserJet printers produce documents that have excellent print quality. They can print on a variety of media types, such as paper (including up to 100% recycled fiber content paper), envelopes, labels, transparencies, and custom-sized media. Paper and transparencies Paper must be of good quality and free of cuts, nicks, tears, spots, loose particles, dust, wrinkles, holes, and curled or bent edges.
Labels When selecting labels, consider the following factors: ■ Adhesives: The adhesive material should be stable at 200°C (392°F), the printer’s maximum temperature. ■ Arrangement: Only use labels with no exposed backing between them. Labels can peel off sheets that have spaces between the labels, causing serious jams. ■ Curl: Before printing, labels must lie flat with no more than 13 mm (0.5 inch) of curl in any direction.
Envelopes with adhesive strips or flaps Envelopes with a peel-off adhesive strip or with more than one flap that folds over to seal must use adhesives compatible with the heat and pressure in the printer: 200°C (392°F). The extra flaps and strips might cause wrinkling, creasing, or jams. Card stock and heavy media For optimum performance, do not use paper heavier than 157-g/m 2 (42-lb).
Loading media Loading media in the HP LaserJet 1010 series printers and the HP LaserJet 1020 printer is simple and straightforward. This section describes loading bulk media to print. Main input tray The main input tray holds up to 150 sheets of 75-g/m2 (20-lb) paper or a 25 mm (0.98 inch) stack of heavier media. Load media with the top forward and the side to be printed on facing up. To prevent jams and skew, always adjust the side and rear media guides.
Setting media types Use the procedure in this section to select the correct type of media for the print job. An incorrect media type setting might cause image-quality problems. Set the media type 26 1 Open the Printer Properties dialog box. 2 Click Printer Preferences. 3 Select the correct media type from the Type Is drop down menu. 4 Click OK to close the Printer Preferences dialog box. 5 Click OK to close the Printer Properties dialog box.
3 Maintenance This chapter describes the life expectancy of parts that wear, printer cleaning, printer maintenance, and the replacement of user-replaceable parts.
Life expectancies of parts that wear Inspect any parts that wear when servicing the product. Replace them as needed, based on failure or wear rather than on usage. The following table lists approximate schedules for replacing consumables.
Table 3-1 Life expectancies of parts that wear (continued) Description Part number Life (estimated) Remarks Q5911-69055 (refurbished) Q5911-67002 (exchange engine w/formatter) ENWW Life expectancies of parts that wear 29
Cleaning the product WARNING! Before you perform these steps, unplug the printer to avoid shock hazard. To maintain quality, thoroughly clean the printer at the following times: ■ Any time a new print cartridge is installed ■ After printing approximately 2,000 pages ■ Whenever print-quality problems appear Clean the outside of the printer with a water-dampened cloth. Clean the inside with only a dry, lint-free cloth (such as a lens tissue). WARNING! Avoid touching the heating element in the fuser.
Cleaning the print path The HP LJ 1010 series and the HP LaserJet 1020 printer feature a special cleaning mode to clean the paper path. NOTE This process requires using a transparency to remove dust and toner from the print paper path. Do not use bond or rough paper. Make sure that the transparency that is used in this cleaning process meets the media requirements for the printer. If transparency film is unavailable, use copier-grade paper (70 to 90 g/m2, or 18 to 24 lb) that has a smooth surface.
Cleaning the print-cartridge area You do not need to clean the print-cartridge area often. However, cleaning this area can improve the quality of printed sheets. 1 Turn off the printer, unplug and remove the power cord. Wait for the printer to cool. 2 Open the print-cartridge door, and remove the print cartridge (HP LJ 1010 series printer shown). CAUTION To prevent damage, do not expose the print cartridge to light. Cover the print cartridge, if necessary.
ENWW 4 Replace the print cartridge, and close the print-cartridge door (HP LJ 1010 series printer shown). 5 Plug in the printer, and then turn it on.
Cleaning the pickup roller If you want to clean the pickup roller rather than replace it, use the following instructions. Remove the pickup roller as described in steps 1 through 5 of Replacing the pickup roller on page 35. With the roller outside the printer, use the following steps to complete the cleaning. 34 1 Dampen a lint-free cloth with water and scrub the roller. 2 Using a dry, lint-free cloth, wipe the pickup roller to remove loosened dirt.
User-replaceable parts To order a new pickup roller or separation pad, go to www.partsdirect.hp.com. Replacing the pickup roller If the printer regularly misfeeds (no media feeds through) and cleaning the pickup roller does not fix the problem, replace the pickup roller. CAUTION ENWW Failure to complete all of the steps in this procedure might damage the product. 1 Turn off the printer, unplug and remove the power cord. Wait for the printer to cool.
4 Gently release the small, white tabs on each side of the pickup roller by pushing them away from the roller, and then rotate the pickup roller toward the front. CAUTION Use gentle pressure to release the small, white tabs to avoid breaking them. 5 Gently pull the pickup roller up and out. 6 Position the new pickup roller in the slot of the previous pickup roller. NOTE Circular and rectangular pegs on each side prevent you from incorrectly positioning the pickup roller.
ENWW 8 Reinstall the print cartridge, and close the print-cartridge door. 9 Plug in the printer, and then turn it on.
Replacing the separation pad If the printer regularly pulls multiple sheets of media at a time, you might need to change the separation pad. Recurring feed problems might indicate that the separation pad is worn. Normal use with good-quality media causes wear. The use of poor-quality media might require more frequent replacement of the separation pad. NOTE Before you change the separation pad, clean the pickup roller. See Cleaning the pickup roller on page 34. To order parts, go to www.partsdirect.hp.com.
ENWW 4 Insert the new separation pad, and screw it in place. 5 Plug the printer in, and then turn it on.
Replacing the main input tray (paper-pickup tray assembly) If you break or damage the main input tray (also called the paper-pickup tray assembly), you can replace it. To order parts, go to www.partsdirect.hp.com. 1 Carefully flex the main input tray just enough to release one side. NOTE Be careful not to break the hinge points. 1 2 3 Figure 3-1 Main input tray (HP LaserJet 1020 printer shown) 2 40 Remove the main input tray.
Replacing the output-bin extension (delivery-tray assembly) If you break or damage the output-bin extension (also called the delivery-tray assembly), you can replace it. To order parts, go to www.partsdirect.hp.com. 1 Carefully flex the sides of output-bin extension just enough to release the hinge pins. NOTE Be careful not to break the hinge pins (callout 1). 1 Figure 3-2 Output-bin extension 2 ENWW Remove the output-bin extension.
Jams Clearing jams CAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to remove jams. Damage caused by sharp objects will not be covered by the warranty. CAUTION Always pull jammed media in the direction it would travel through the paper path. Do not pull jammed media against the direction of travel through the paper path to avoid damage to the printer.
Removing a jammed page Use the procedures in this section to remove a jam. CAUTION Media jams might result in loose toner on the page. If you get any toner on your clothes, wash them in cold water. Hot water will permanently set the toner into the fabric. CAUTION To prevent damage to the printer when clearing jams, including jams in the output bin, always open the print cartridge door and remove the print cartridge. To prevent damage to the print cartridge, minimize its exposure to direct light.
3 When you have removed the jammed media, replace the print cartridge, and close the print cartridge door. After clearing a media jam, you might need to turn the printer off then on again. NOTE When you add new media, remove all of the media from the input tray and straighten the stack of new media.
4 Operational overview This chapter describes the general components of the HP LaserJet 1010 series printers and the HP LaserJet 1020 printer, and the theory of operation for the printers.
Basic functions The following are the major systems of the printer: ■ Formatter and I/O functions ■ ■ Formatter system Printer functions and operation ■ Engine-control system (engine control unit [ECU] and engine power assembly) ■ Image-formation system ■ Paper-feed system FORMATTER COMPUTER PRINTER ENGINE UNIT ECU Figure 4-1 Basic configuration 46 Chapter 4 Operational overview ENWW
Formatter system The formatter coordinates the major systems.
Draft mode (EconoMode) Depending on which driver is used, selecting draft or EconoMode from the driver allows the product to use less toner, extending the life of the print cartridge. There is a change in print quality when this setting is used. NOTE HP does not recommend the full-time use of EconoMode. If EconoMode is used full-time when the average toner coverage is very low, it is possible that the toner supply will outlast the mechanical parts of the print cartridge.
PJL overview When the host computer is connected through the parallel port on the HP LaserJet 1015 printer, Printer Job Language (PJL) is an integral part of configuration (in addition to the standard PCL). When an IEEE 1284-compliant parallel cable (standard ECP cabling) is attached, PJL provides the following functions: ■ Two-way communication with the host computer through a bidirectional parallel connection. The printer can communicate information to the host (such as the control-panel status).
Printer functions Printer functions are divided into five groups: ■ Engine control ■ Formatter ■ Image formation ■ Laser/scanner ■ Pickup and feed The following figure is a block diagram of the printer: Figure 4-2 Printer functional-block diagram Engine control system (engine control unit and power assembly) The engine control system coordinates all print engine activities. The engine control system includes both the engine control unit (ECU) PCA and the engine-power-assembly PCA.
The ECU controls the following systems and functions: ■ ■ Printer-engine control ■ Paper-motion monitoring and control (printing) ■ Motor Printer laser/scanner unit The engine-power assembly provides the following features in the power system: ■ AC power distribution ■ DC power distribution ■ Overcurrent/overvoltage protection ■ High-voltage power distribution Printer-engine-control system Paper motion monitoring and control The ECU controls paper motion in the printer by continuously monitor
Printer laser/scanner unit The ECU sends signals to the laser/scanner assembly to modulate the laser diode on and off modes and to drive the laser/scanner motor.
Power system on the engine power assembly The engine-power assembly provides the ac, dc, and high-voltage power supply circuits. AC power distribution The ac power circuitry supplies ac voltage whenever the power cord is connected to the ac power source and the power switch is on. AC voltage is distributed to the dc power supply circuitry and to the ac driver circuitry, which controls ac voltage to the fuser-assembly heating element.

The seven image-formation processes Paper Pickup Figure 4-5 Image formation-block diagram ENWW 1 Conditioning stage (primary charging)—This process applies a uniform negative charge to the surface of the drum with the primary charging roller, which is located in the print cartridge. The primary charging roller is coated with conductive rubber. An ac bias is applied to the roller to erase any residual charges from any previous image.
6 Fusing stage—During this process, the heat and pressure fuse the toner into the media to produce a permanent image. The media passes between a heated fusing element and a soft pressure roller, which melt the toner and press it into the media. 7 Drum-cleaning stage—During this process, the cleaning blade is in contact with the surface of the drum at all times. As the drum rotates during printing, the cleaning blade wipes excess toner off the drum and stores it in the waste toner receptacle.

6 Troubleshooting This chapter describes how to isolate and resolve printer problems, print-quality problems, and media problems. Troubleshooting details are provided to resolve problems or to isolate replaceable parts.
Basic troubleshooting Troubleshooting checklist Table 6-1 Basic troubleshooting Did the printer turn on? Cause Solution No power is available because the power source, cable, or switch failed. 1 Verify that the product is plugged in. Make sure that the printer is plugged directly into a working wall receptacle. 2 Verify that the power cable is functional and that the power switch is on. 3 If these conditions are correct, replace the engine power assembly.
Table 6-1 Basic troubleshooting (continued) Print a demo page by pressing the GO button (HP LJ 1010 series only) when the printer is idle. Does the demo page print? Cause Solution The media does not move smoothly through the paper path. If the media is consistently jamming and the paper path is clear, replace either the paper-pickup assembly or the fuser, depending on where it is jamming. Poor print quality is evident. See Print-quality troubleshooting on page 111.
Control-panel power-on functions (HP LaserJet 1010 series printers) Turning on the printer while pressing the GO button for varying amounts of time provides important printer functionality for resetting the printer, resetting NVRAM, and performing self-tests. Use the following procedure to initiate a power-on function, see on page 100 for the specific time ranges for the poweron functions. 1 Turn off the printer. 2 Press and hold the GO button.
Control-panel pages (HP LaserJet 1010 series printers only) When the printer is in the Ready state, pressing the GO button for varying amounts of time produces important printer reports. Use the following procedure to initiate the reports, and see Table 6-3 Controlpanel pages: time ranges (HP LJ 1010 series printers only) on page 101 for the specific time ranges for each report. 1 Ensure that only the READY light is on. 2 Press and hold the GO button.
Control-panel lights (HP LaserJet 1010 series printers) The printer indicates status and errors through patterns of the GO, READY, and ATTENTION lights. If any lights are blinking, the error can usually be resolved. 1 If the error pattern occurs when printing, try pressing the GO button to continue. 2 Make sure that the print cartridge is installed correctly and the print-cartridge door is closed. 3 Turn the printer power off and then on again.
Table 6-4 Control-panel light patterns (HP LJ 1010 series printers) (continued) Printer status Processing data (The printer is processing or receiving data.) Lights Description Go Ready Attention Job cancellation During data processing, the READY light is blinking and the GO and ATTENTION lights are off. Pressing the GO button cancels the current job without printing another page. The printer returns to the Ready state after the job has been canceled.
Table 6-4 Control-panel light patterns (HP LJ 1010 series printers) (continued) Printer status Lights Description NOTE The LJ 1010 series printers do not have paper-out sensors. When the printer enters a continuable error state because it is out of paper, the user needs to reload paper and press the GO button to continue. The lights provide no secondary error information. Attention state Go Ready Attention In the Attention state, the ATTENTION light is blinking and the GO and READY lights are off.
Table 6-4 Control-panel light patterns (HP LJ 1010 series printers) (continued) Printer status Cleaning page Lights Description Use the HP Toolbox to initiate the cleaning function. Pressing the GO button has no effect during the cleaning mode. Go Ready Attention Sleep mode From the customer's perspective, sleep mode is the same as Ready mode.
Control-panel lights (HP LaserJet 1020 printer) The ATTENTION and READY lights indicate printer status and errors. Figure 6-2 Control-panel lights (HP LJ 1020 printer) Status-light patterns Off On Blinking Figure 6-3 Control-panel-light legend (HP LJ 1020 printer) Table 6-5 Control-panel light patterns (HP LJ 1020 printer) Light status State of the printer Action Ready No action is necessary. The product is ready to print. Processing data Wait for the job to print.
Table 6-5 Control-panel light patterns (HP LJ 1020 printer) (continued) Light status State of the printer Action Out of memory The page you are printing might be too complex for the printer's memory capacity. Try lowering the resolution. The printer is out of memory. Attention: door open, no print cartridge, or media jam Check the following: ■ The print cartridge door must be completely closed. ■ The print cartridge is correctly installed. ■ There is no media jam.
Jams Clearing jams CAUTION Do not use sharp objects, such as tweezers or needle nose pliers, to remove jams. Damage caused by sharp objects will not be covered by the warranty. CAUTION Always pull jammed media in the direction it would travel through the paper path. Do not pull jammed media against the direction of travel through the paper path to avoid damage to the printer.
CAUTION To prevent damage to the printer when clearing jams, including jams in the output bin, always open the print cartridge door and remove the print cartridge. To prevent damage to the print cartridge, minimize its exposure to direct light. Cover the print cartridge with a sheet of paper. NOTE The following illustrations show the HP LaserJet 1020 printer. The same procedure is used to remove a jam in the HP LaserJet 1010 series printers. 1 Open the print cartridge door, and remove the print cartridge.
3 When you have removed the jammed media, replace the print cartridge, and close the print cartridge door. After clearing a media jam, you might need to turn the printer off then on again. NOTE When you add new media, remove all of the media from the input tray and straighten the stack of new media.
Print-quality troubleshooting Print-cartridge problems Checking the print cartridge Image-formation defects are frequently the result of problems in the print cartridge. If there is any doubt, always replace the print cartridge before troubleshooting image defects. Hint If the transfer roller was recently replaced, print-quality problems might be the result of skin oils on the black-sponge portion of the transfer roller. Do not touch the black-sponge portion of the transfer roller when replacing it.
Table 6-6 Solving print-quality problems (continued) Output pages are blank. Cause Solution The tape was not removed from the print cartridge. Remove the print cartridge, remove the tape, and reinstall the print cartridge. The print cartridge is out of toner. Replace the print cartridge The high-voltage connection between the printer and the print cartridge has been interrupted. Perform a High-voltage-contacts check on page 127.
Table 6-6 Solving print-quality problems (continued) Random toner specks appear on the printed page. Cause Solution The media in use does not meet HP specifications (for example, it is too moist or too rough). Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Print Media Guide. The print path is dirty. Clean the print path (see Cleaning the print path on page 31). Characters are only partially printed (also referred to as dropouts).
Table 6-6 Solving print-quality problems (continued) Characters are only partially printed (also referred to as dropouts). Cause Solution Preferences dialog box, and then click OK again to close the Printer properties dialog box. The print cartridge is depleted or damaged. Replace the print cartridge. Rarely, the fuser might be damaged. Replace the fuser. Vertical black lines appear on the printed page. Cause Solution The print cartridge is depleted or damaged. Replace the print cartridge.
Table 6-6 Solving print-quality problems (continued) The printed page has a gray background. Cause Solution Preferences dialog box, and then click OK again to close the Printer properties dialog box. The print density is too high. HP LJ 1010: Adjust the print density from the HP Toolbox (on the Settings tab) or open the Printer Properties dialog box, and then select the Configure tab. Use the slide bar in the Print Density area of the dialog box to change the print density setting.
Table 6-6 Solving print-quality problems (continued) Toner smears appear on the printed page. Cause Solution The wrong type of media is selected in the Printer Preferences dialog box. Open the Printer Properties dialog box, and then click Printing Preferences. Select the correct media type from the Type Is drop down menu. Click OK to close the Printing Preferences dialog box, and then click OK again to close the Printer properties dialog box. The fuser is damaged.
Table 6-6 Solving print-quality problems (continued) The toner is loose, and it does not stay attached to the printed page. Cause Solution If, after replacing the fuser, the error persists, replace the engine power assembly. Repetitive vertical defects appear on the printed page. ENWW Cause Solution The internal parts have toner on them. If the defects occur on the back of the page, the problem will probably correct itself after a few more printed pages.
Table 6-6 Solving print-quality problems (continued) Characters are poorly formed and are producing hollow images. Cause Solution The wrong type of media is selected in the Printer Preferences dialog box. Open the Printer Properties dialog box, and then click Printing Preferences. Select the correct media type from the Type Is drop down menu. Click OK to close the Printing Preferences dialog box, and then click OK again to close the Printer properties dialog box. The media is too slick or too thick.
Table 6-6 Solving print-quality problems (continued) The printed page has curls or waves. Cause Solution The printer is operating in humidity or temperature conditions that are not within the recommended ranges. Move the product to a different location. The wrong type of media is selected in the Printer Preferences dialog box. Open the Printer Properties dialog box, and then click Printing Preferences. Select the correct media type from the Type Is drop down menu.
Table 6-6 Solving print-quality problems (continued) Vertical white stripes appear. Cause Solution The toner is low or poorly distributed in the print cartridge. Gently rock the print cartridge back and forth to redistribute the toner (see the illustration on the print cartridge). Replace the print cartridge. The media you are using does not meet HP specifications (for example, it is too moist or too rough).
Table 6-6 Solving print-quality problems (continued) Wrinkles or creases appear in the printout Cause Solution The media is not properly loaded. Make sure the media is correctly loaded. Damage or reused media is being used. Do not use media that is damaged or has already been put through a copier or printer. The media you are using does not meet HP specifications (for example, it is too moist or too rough).
Solving paper-feed problems Use the following table to solve problems related to moving paper or documents through the product. Table 6-7 Solving paper-feed problems Pages are coming out curled or wrinkled. Cause Solution Paper curl is inherent to the laser printing processes, and occurs when paper is subjected to heat. Paper curl tends to relax as the paper cools while resting on a flat surface. Make sure that the media meets the specifications detailed in the HP LaserJet family Print Media Guide.
Table 6-7 Solving paper-feed problems (continued) The printer feeds multiple sheets or jams frequently from the main input tray or priority input slot. ENWW Cause Solution The paper guides are not adjusted correctly or the paper is not far enough forward. Slide the guides against the sides of the stack in the main input tray or the priority input slot to center the paper. Make sure that the guides are not adjusted too tightly. The stack is not neat or not aligned well on all sides.
Functional checks This section includes five functional checks for troubleshooting.
4 Check the fuser connections (callout 1) on the engine-power assembly. Also check the high voltage connection at the back side of the printer. NOTE The following figure shows the HP LaserJet 1010 series products. The connections are located at the same place on the HP LaserJet 1020 printer. Figure 6-4 Check the fuser connections (HP LaserJet 1010 series shown) If a transfer problem exists, replace the transfer roller (do not touch the black-sponge portion of the transfer roller).
Drum-rotation functional check The photosensitive drum, which is located in the print cartridge, must rotate in order for the print process to work. The photosensitive drum receives its drive from the main motor through a system of gears on the right side of the printer. NOTE This test is especially important if refilled print cartridges have been used. 1 Open the print-cartridge door. 2 Remove the print cartridge. 3 Mark the drive gear on the cartridge with a felt-tipped marker.
High-voltage-contacts check The high-voltage contacts in the printer must have a good connection with the contacts on the print cartridge to provide the necessary voltages for the electrophotographic processes. To check the print-cartridge contacts Remove the print cartridge and visually inspect the three connection points (callout 1) on the end of the print cartridge. If they are dirty or corroded, clean the connection. If they are damaged, replace the print cartridge.
To check the printer high-voltage contacts The printer has three spring-loaded pins (callout 1) that make contact with the high-voltage points on the print cartridge. Verify that the pins are not dirty or corroded and that the spring-loading action is functional. If the pins are dirty or obstructed, clean them. If they are damaged, replace the printer.
