Basic operation This chapter presents an overview of the relationships between major components in the product, and includes a detailed discussion of the image-formation system. The following systems are discussed: ● Engine control system ● Laser/scanner system ● Pickup/feed/delivery system ● Image-formation system Figure 4-1 HP LaserJet M2727 MFP system block diagram Sequence of operation for the base unit Operational sequences are controlled by the microprocessor and the DC controller.
Table 4-1 Sequence of operation (continued) Name Timing Purpose PRINT From the end of the INTR period until the primary high-voltage is turned off Forms the image on the photosensitive drum and transfers the toner image to the media LSTR (last rotation) From the end of the PRINT period (when high-voltage Delivers the last page of a print job is turned off) until the main motor stops rotating After LSTR, the product either returns to STBY or, if another print command was sent from the formatter, enter
Scanner and ADF functions and operation The following sections describe how the document scanner and the automatic document feeder (ADF) function. Scanner functions The scanner uses a light source, a color-separation method, and a charge-coupled device array (CCD) to collect optical information about the document and transform that into an image file.
Scanner operation At power-on and periodically at other times, the scanner assembly moves systematically to locate its home position. It then calibrates to a white strip located under the glass at the right end of the scan tub. If the product detects a document in the ADF when a copy or scan is initiated (from the software or the control panel), the scan module moves to the left side of the scan tub and stops. The image is acquired as the paper is fed through the ADF past the scanner module.
ADF paper path and ADF sensors The following diagram shows the ADF paper path. Figure 4-3 ADF paper path Paper present sensor Pick roller Stack stop Pre-pick roller Picks top sheet ADF door open flag RAY UT T INP Separation pad Cleanout PAGE EJECTS FULLY Form sensor OUTPUT AREA Postscan rollers Prescan rollers ADF glass The paper-present sensor determines if paper is in the ADF. The form sensor detects the top and bottom edges of the document. One other sensor detects an open ADF door.
ADF jam detection The ADF has two sensors that detect paper. The paper-present sensor detects the presence of media in the ADF input tray. The form sensor detects media moving through the ADF. If a jam is detected, the ADF immediately stops the paper feeding and a jam message appears on the control-panel display. A jam can be detected under any of the following conditions: ENWW ● Document-feeder jam.

Engine control system The engine control system coordinates all of the product functions, according to commands sent from the formatter. It drives the laser/scanner system, the image-formation system, and the pickup/feed/ delivery system.

Laser/scanner system The laser/scanner system receives video signals from the DC controller and the formatter, and converts the signals into latent images on the photosensitive drum.
Pickup/feed/delivery system The pickup/feed/delivery system consists of several types of feed rollers and sensors. The DC controller uses two motors and two solenoids to drive the rollers. Three media-detection sensors detect media as it passes through the printer. If media does not reach or pass each sensor within a specified time period, the DC controller determines that a jam has occurred and alerts the formatter.
NOTE: This sensor has two sensor flags; one flag detects the media when it is delivered from the fuser, and the other flag detects the media when it is reversed for duplexing.
Image-formation system Laser printing requires the interaction of several technologies, including electronics, optics, and electrophotographics, to produce a printed page. Each process functions independently and must be coordinated with the other product processes.
Step 2: Laser beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is formed on the drum where negative charges were neutralized. Step 3: Developing The developing cylinder comes in contact with the photosensitive drum to deposit toner onto the electrostatic latent image. NOTE: The charges on the exposed area of the drum are shown as positive in Figure 4-11 Developing on page 84.
Figure 4-12 Transfer Step 5: Separation The elasticity of the print media causes its separation from the photosensitive drum. A static-charge eliminator aids separation by weakening any electrostatic adhesion. Figure 4-13 Separation Step 6: Fusing The DC negative bias applied to the fusing film strengthens the holding force of the toner on the print media and prevents the toner from scattering.
Figure 4-14 Fusing Step 7: Drum cleaning The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste-toner case.
Fax functions and operation The following sections describe the product fax capabilities. Computer and network security features The product can send and receive fax data over telephone lines that conform to public switch telephone network (PSTN) standards. The secure fax protocols make it impossible for computer viruses to be transferred from the telephone line to a computer or network.
NOTE: In order for the 1-2-3 sequence to work, the extension phone setting must be set to On in the Fax setup menu. Distinctive ring function Distinctive ring is a service that a telephone company provides. The distinctive ring service allows three phone numbers to be assigned to one phone line. Each phone number has a distinctive ring. The first phone number has a single ring, the second phone number has a double ring, and the third phone number has a triple ring.
If you experience problems using the fax feature on a VoIP network, ensure that all of the product cables and settings are correct. Configuring the Fax Speed setting to Medium(V.17) or Slow(V.29) can also improve your ability to send a fax over a VoIP network. See Table 6-8 Fax setup menu on page 194. If you continue to have problems faxing, contact your VoIP provider. The fax subsystem The formatter, fax card, firmware, and software all contribute to the fax functionality.
All communications cross the isolation barrier magnetically. The breakdown voltage rating of barriercritical components is greater than 5 kV. Data path TIP and RING are the two-wire paths for all signals from the telephone network. All signaling and data information comes across them, including fax tones and fax data. The telephone network uses DC current to determine the hook state of the telephone, so line current must be present during a call.
Ring detect Ring detect is performed by the line voltage monitoring module of the silicon DAA, and is a combination of voltage levels and cadence (time on and time off). Both must be present to detect a valid ring. The CODEC works with DSP as well as the firmware to determine if an incoming signal is an answerable ring. Line current control The DC current from the CO needs to have a path to flow from TIP to RING.
the original document immediately after it is scanned, eliminating the need to wait until the fax is transmission is complete. Because fax pages are stored in flash memory rather than RAM, more RAM is available to handle larger and more complicated copy and print jobs.

Print problems Print-quality problems The information in the following sections helps you identify and resolve print-quality issues. NOTE: If you are having copy problems, see Copy problems on page 214. Improve print quality Use the print-quality settings to prevent print-quality problems. Print-quality settings Print-quality settings affect how light or dark the print is on the page and the style in which the graphics are printed.
3. Click Properties, or click Printing Preferences. 4. Change the settings, and click OK. Identify and correct print defects Use the checklist and print-quality issues charts in this section to solve print-quality problems. Print-quality checklist General print-quality problems can be solved by using the following checklist: 1. Make sure that the paper or print media that you are using meets specifications. Generally, smoother paper provides better results. 2.
Problem Example Print is light or faded. Cause Solution The media might not meet HP specifications. Use media that meets HP specifications. Make sure that the media meets specifications in the HP LaserJet Printer Family Print Media Guide. The print cartridge might be low. If you use a non-HP print cartridge, no messages appear on the product control panel or in the HP ToolboxFX. Replace the print cartridge. See Remove the print cartridge on page 99.
Problem The amount of background toner shading becomes unacceptable. Toner smears appear on the media. ENWW Example Cause Solution The media might not meet HP specifications. Use a different paper with a lighter basis weight. The single-sheet priority input slot (tray 1) might be installed incorrectly. Make sure that the single-sheet priority input slot (tray 1) is in place. The print-density setting is too high. Decrease the print-density setting through HP ToolboxFX or the embedded Web server.
Problem Example The toner smears easily when touched. Marks repeatedly appear at even intervals on the page. The printed page contains misformed characters. 208 Chapter 6 Solve problems Cause Solution The product is not set to print on the type of media on which you want to print. In the printer driver, select the Paper tab and set Type is to match the type of media on which you are printing. Print speed might be slower if you are using heavy paper. The media might not meet HP specifications.
Problem The printed page is curled or wavy. Example Cause Solution The product is not set to print on the type of media on which you want to print. In the printer driver, make sure the appropriate media type is selected. If the problem persists, select a media type that uses a lower fuser temperature, such as transparencies or light media. Text or graphics are skewed on the printed page. The printed page contains wrinkles or creases. The media might have been in the input tray too long.
Problem Example Toner appears around the printed characters. An image that appears at the top of the page (in solid black) repeats farther down the page (in a gray field). Cause Solution The media might be loaded incorrectly. Turn over the stack of paper in the tray. If large amounts of toner have scattered around the characters, the paper might have high resistivity. Use a different paper, such as high-quality paper that is intended for laser printers.
Scan problems Solve scanned-image problems Problem Cause Solution The scanned image is of poor quality. The original might be a secondgeneration photo or picture. ● To eliminate the patterns, try reducing the size of the image after scanning. ● Print the scanned image to see if the quality is better. ● Verify that your resolution and color settings are correct for the type of scan job that you are performing.
Problem Cause Solution Part of the image did not scan. The original might have been loaded incorrectly. Use the media guides when you load the originals into the ADF. See Load documents to fax, copy, or scan on page 26. A colored background might be causing images in the foreground to blend into the background. Try adjusting the settings before you scan the original, or try enhancing the image after you scan the original. The original is longer than 381 mm (15 inches).
Scan-quality problems Prevent problems The following are a few simple steps you can take to improve copy and scan quality. ● Use the flatbed scanner, rather than the automatic document feeder (ADF) input tray, to scan. ● Use high-quality originals. ● Load the media correctly. If the media is loaded incorrectly, it might skew, which causes unclear images. See Load paper and print media on page 26 for instructions. ● Adjust the software settings according to how you plan to use the scanned page.
Copy problems Prevent problems The following are a few simple steps you can take to improve copy quality: ● Copy from the flatbed scanner. This will produce a higher quality copy than copying from the automatic document feeder (ADF). ● Use quality originals. ● Load the media correctly. If the media is loaded incorrectly, it might skew, causing unclear images and problems with the OCR program. ● Use or make a carrier sheet to protect your originals.
Problem Cause Solution Unwanted lines appear on the copy. Tray 2 might not be installed correctly. Verify that the tray is in place. The flatbed scanner or the ADF glass might be dirty. Clean the flatbed scanner or the ADF glass. See Clean the product on page 49. The photosensitive drum inside the print Install a new HP print cartridge. See Remove the print cartridge on page 99. cartridge might have been scratched. Black dots or streaks appear on the copy.
Problem Cause Solution Problems with feeding. The paper has ragged edges. Use high-quality paper that is made for laser printers. The paper varies from side-to-side. Turn the paper over. The paper is too moist, too rough, too heavy or too smooth, has the wrong grain direction, or is of short-grain construction or it is embossed or from a faulty paper lot. Try another kind of paper, between 100 and 250 Sheffield, 4% to 6% moisture content. Print is skewed (crooked).
Performance problems Problem Cause Solution No copy came out. The input tray might be empty. Load media in the product. See Load paper and print media on page 26 for more information. The original might have been loaded incorrectly. In the automatic document feeder (ADF), load the original with the narrow side forward and the side to be scanned facing up. On the flatbed scanner, place the original document face-down with the upper-left corner of the document at the lower-right corner of the glass.
Fax problems General fax problem-solve Verify the following information before problem-solving fax problems. ● Is the fax set up correctly? ◦ Make sure that the fax cord that came with the product is the cord that is being used. This cord has been tested and meets the device specifications. ◦ Make sure that the fax cord is installed in the correct port. The fax cord (from the wall receptacle) must be plugged into the line port ( ◦ ● ● ).
NOTE: Hewlett-Packard does not recommend using a parallel splitter (T-splitter) with the product because it might degrade the quality of the telephone signal. If a second device must be attached to the telephone line in addition to the product, plug the second device into the telephone port on the product (the port on the back that is marked with a telephone icon).
Problem Cause Solution The product is not answering incoming fax calls. The answer mode might be set to Manual. If the answer mode is set to Manual, the product does not answer calls. You have to start the fax-receiving process manually. The rings-to-answer setting might not be set correctly. Check the rings-to-answer setting for your configuration. The answer-ring pattern feature might be turned on, but you do not have the service, or you do have the service and the feature is not set correctly.
Problem Cause Solution The product is not answering incoming fax calls. A voice-messaging service might be interfering with the product as it attempts to answer calls. Do one of the following: Faxes are not printing. Faxes are printing on two pages instead of one. Received faxes are too light or are printing only on half of the page. ENWW ● Disable the messaging service. ● Get a telephone line that is dedicated to fax calls. ● Set the product answer mode to Manual.
Problems sending faxes Problem Cause Solution The document stops feeding in the middle of faxing. The maximum length of a page that you can load is 381 mm (15 inches). Faxing of a longer page stops at 381 mm (15 inches). Print the document on shorter media. If the item is too small, it can jam inside the automatic document feeder (ADF). If no jam exists and less than one minute has elapsed, wait a moment before pressing Cancel. If a jam exists, see Clear jams on page 179. Then, resend the job.
ENWW Problem Cause Solution Faxes that you send are not arriving at the receiving fax machine. The receiving fax machine might be off or might have an error condition, such as being out of paper. Call the recipient to verify that the fax machine is on and ready to receive faxes. The originals might be incorrectly loaded. Verify that the original documents are correctly loaded into the ADF input tray or flatbed scanner. See Load paper and print media on page 26.
Voice-call problems Problem Cause Solution The telephone or answering machine that is connected to the line is not receiving voice calls. The fax cord might not be correctly connected. See the Getting Started Guide to check the installation. The product must be the first device connected to the telephone line. The answer mode or rings-to-answer settings might not be correctly set. The rings-to-answer must be set higher than the answering machine setting.
Media-handling problems NOTE: For information about removing jams, see Clear jams on page 179. Problem Cause Solution Print is skewed (crooked). The media input tray might be overloaded. Remove some of the media from the input tray. The media guides might be incorrectly set, broken, or missing. Verify that the guides are not adjusted too tightly or too loosely against the paper. Check for broken or missing guides, and replace them if necessary. The media might not meet HP specifications.
Performance problems Problem Cause Solution Faxes are transmitting or being received very slowly. The fax might be very complex, such as one with many graphics. Complex faxes take longer to be sent or received. Breaking longer faxes into multiple jobs can increase the transmission speed. The receiving fax machine might have a slow modem speed. The product only sends the fax at the fastest modem speed that the receiving fax machine can accept.
Control-panel display problems CAUTION: Static electricity can cause unexpected black lines or dots to appear on the product controlpanel display. Do not touch the product control-panel display if there is a chance that you have collected a static electric charge (for example, by walking on carpet in a low-humidity environment). Unexpected lines or dots might appear on the product control-panel display, or the display might become blank if the product is exposed to an electric or magnetic field.
DSL problems A digital subscriber line (DSL) uses digital technology over standard copper phone wires. These DSL services rely on an AM signal. The product is a Group 3 fax device, which operates below the DSL capability and is not directly compatible with digital signals.
ADF problems The “Document loaded” message continually appears on the control-panel display. Cause Solution The ADF paper-sensor flag is damaged. Replace the ADF. See ADF assembly on page 115. The “Scanner error” message continually appears on the control-panel display. Cause Solution The ADF-to-scanner connector is not connected correctly or the ADF is not functioning. Reseat the connector. If the problem persists, replace the ADF. See ADF assembly on page 115. The ADF pickup roller does not move.
Functional checks Drum rotation test The photosensitive drum, located in the print cartridge, must rotate in order for the print process to work. The photosensitive drum receives its drive from the main-drive assembly. 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. Note the position of the mark. 4.
Engine test The engine test is used to verify that the print engine is functioning correctly. The formatter is bypassed during the engine test. To perform an engine test 1. Remove the left cover. See Left cover on page 102. 2. Use a non-conductive probe to depress the engine-test switch. A single test page prints. CAUTION: Use a non-conductive probe to depress the engine test switch. Inserting a conductive probe to depress the switch can damage the product.
Half self-test functional check The print process can be subdivided into the following stages: ● Image formation stage (charges the drum and writes a latent image to the drum with the laser) ● Development stage (forms a toner image on the drum) ● Transfer stage (transfers the image to the media) ● Cleaning stage (removes excess toner from the drum) ● Fusing stage (applies heat and pressure to the media to make the image permanent) Perform a half self-test check The purpose of the half self-test ch
Heating element check Media passes between the heating element and a soft pressure roller to fuse toner to the media. 1. Unplug the product for at least ten minutes. 2. Verify that the thermistor connector is seated into both the product chassis and the ECU. 3. Remove the heating element connector from the ECU. To measure the continuity of the heating element, measure the resistance between the two pins at the end of the cable.
