4 Maintenance Chapter contents Chapter contents............................................................................................................... ....... 49 Replacing the print cartridge........................... ........................
Replacing the print cartridge Use the below instructions to remove or replace the print cartridge. To replace the print cartridge 1. Open the print-cartridge door, and remove the print cartridge. CAUTION To prevent damage, do not expose the print cartridge to light.
Cleaning the printer Clean the outside of the printer with a clean, damp cloth when necessary. WARNING! Before cleaning the printer, turn the printer off, unplug the power cord, and wait for the printer to cool. CAUTION Do not use ammonia-based cleaners on or around the printer.
2. Using a dry, lint-free cloth, wipe any residue from the media path area and the print cartridge cavity. 3. Replace the print cartridge, and close the print-cartridge door.
Cleaning the printer media path If you are experiencing toner specks or dots on the printouts, clean the printer media path. This process uses a transparency to remove dust and toner from the media path. Do not use bond or rough paper. NOTE For best results use a sheet of transparency.
Changing the pickup roller Normal use with good media causes wear. The use of poor media might require more frequent replacement of the pickup roller. If the printer regularly mispicks (no media feeds through), you might need to change or clean the pickup roller.
3. Remove tray 2. 4. Open the front automatic two-sided-printing path door (HP LaserJet 1320 Series printer only). 5. Place the printer on the work surface with the front of the printer facing up.
6. Pull the white tabs outward, and rotate the tabs up. 7. Slide the right tab to the right, and leave the tab in this position throughout the procedure.
8. Slide the pickup roller assembly to the right, and remove the left end cap. 9. Remove the pickup roller. ENWW Changing the pickup roller 57.
10. Insert the left side of the new pickup roller into the left slot (1), and insert the right side (with notches in the shaft) into the right slot (2).
15. Close the front automatic two-sided-printing path door. 16. Reinstall the print cartridge, and close the print-cartridge door. 17. Plug the power cord into the printer and then turn on the printer.
Cleaning the pickup roller If you want to clean the pickup roller rather than replace it, follow these instructions: 1. Remove the pickup roller as described in steps 1 through 9 of Changing the pickup roller . 2. Dab a lint-free cloth in water, and scrub the roller.
Changing the printer separation pad Normal use with good media causes wear. The use of poor media might require more frequent replacement of the separation pad. If the printer regularly pulls multiple sheets of media at a time, you might need to change the separation pad.
3. Remove the screws. 62 Chapter 4 Maintenance ENWW.
4. Remove the separation pad. NOTE Before you proceed to step 4, examine the position of the separation pad in the tray. 5. Insert the new separation pad.
6. Replace the screws. 64 Chapter 4 Maintenance ENWW.

Introduction This chapter presents an overview of the relationships between major components in the printer, 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 5-1.
Internal components Figure 5-2. Cross-section of printer highlights the major internal components. Figure 5-2. Cross-section of printer 1 Top output bin delivery roller 2 Fuser film 3 Laser/scanner 4 .
Timing Sequence of operation Operation sequences are controlled by the microprocessor on the dc controller. Table 5-1. Sequence of operation describes engine operations for each period of a print operation.
Step Action 8 High-voltage control Detect presence of a print cartridge Clean the transfer roller after the primary charging ac bias is turned on 9 Failure/abnormality check: detect laser/scanner failure, fuser failure, and open covers 10 Communication with the memory tag Table 5-2.
Engine control system The engine control system coordinates all printer functions, according to commands sent from the formatter. It drives the laser/scanner system, the image-formation system, and the pickup/feed/delivery system. The engine control system contains the following components: ● Dc controller ● High-voltage PCA Figure 5-3.
Figure 5-4. To be written ENWW Engine control system 73.
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.
● PS915, fuser delivery sensor ● PS915, duplex sensor (HPLJ 1320 only) Figure 5-6. Pickup/feed/delivery system 76 Chapter 5 Theory of operation ENWW.
Image-formation system Laser printing requires the interaction of several different technologies, including electronics, optics, and electrophotographics, to provide a printed page. Each process functions independently and must be coordinated with the other printer processes.
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 5-9. Developing . The charges are actually negative, but they are more positive than the charges on the developing cylinder.
The elasticity of the print media causes its separation from the photosensitive drum. A static charge eliminator aids separation by weakening any electrostatic adhesion.
The cleaning blade scrapes the residual toner off of the photosensitive drum and deposits it into the waste toner case. Figure 5-13. Drum cleaning 80 Chapter 5 Theory of operation ENWW.

Image 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.
Solving print image-quality problems Table 7-8. Solving print image-quality problems Pages do not print or pages are blank. Cause Solution The printer is not plugged in or power switch is off. Make sure that the printer is plugged into a live wall outlet or power strip and that the printer is turned on.
Toner specks appear on the printed page. . Cause Solution The media you are using does not meet HP's specifications (for example, it is too moist or too rough). Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Media Guide .
Vertical black lines appear on the printed page. Cause Solution The photosensitive drum inside the print cartridge is scratched. Replace the print cartridge. The fuser is defective. Replace the fuser (see Fuser ). The printed page has a gray background.
Toner smears appear on the printed page. Cause Solution If the toner smears appear on the leading edge of the media, the media guides are dirty. Wipe the media guides with a dry, lint-free cloth. The media you are using does not meet HP's specifications (for example, it is too moist or too rough).
The toner is loose, and it does not stay attached to the printed page. Cause Solution The fuser temperature is too low. Select Type is: in the Paper/Quality tab of the printer driver. Make sure that it is set for the appropriate media. If the problem persists, replace the fuser (see Fuser ).
Characters are misformed and are producing hollow images. Cause Solution The media is too slick. Try a different media. Make sure that the media meets specifications detailed in the HP LaserJet Printer Family Media Guide . The printer driver is not set for the correct media.
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 printer to a different location. The media was in the input tray for too long. Turn the stack of media over and put it back in the tray.
Droplets of water are deposited on the trailing edge Cause Solution Moisture in the printer is condensing on the fuser assembly and dropping onto the media. In excessively hot and humid areas, media retains moisture. Try a different media. Store media in airtight containers to minimize absorption of moisture.
Clearing jams Occasionally, media becomes jammed during a print job. You are notified of a media jam by an error in the software and the printer control panel lights. See Status light patterns for more information. The following are some of the causes of media jams: ● The input trays are loaded improperly or too full.

Functional checks This section includes five functional checks for troubleshooting. Engine test The engine test is used to verify that the print engine is functioning correctly. The formatter is bypassed during an engine test, so the engine test is useful for isolating printer problems.
● cleaning stage (removes excess toner from the drum) ● fusing stage (applies heat and pressure to make the image on paper permanent) To perform a half self-test check The purpose of the half self-test check is to determine which process is malfunctioning.
Drum rotation functional check The photosensitive drum, located in the print cartridge, must rotate 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.
Heating element check Paper passes between the heating element and a soft pressure roller to fuse toner to the paper. 1. Unplug the printer for at least ten minutes. 2. Verify that the thermistor connector is seated into both the printer chassis and the ECU.
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.
Wired network setup problemsolving If the computer is unable to discover the HP LaserJet 1320n, HP LaserJet 1320tn, or HP LaserJet 1320nw printer, perform the following steps: 1.
NVRAM initialization CAUTION Only perform the following procedure if absolutely necessary. Performing an NVRAM initialization resets some parameters that cannot be restored later. NVRAM initialization sets all default variables stored in NVRAM back to factory default values or to a default ROM value, depending on the variable.
Cold reset A cold reset changes most system parameters in NVRAM to the factory defaults. However, unlike NVRAM initialization, a cold reset does not reset the page count, the paper tray sizes, language, or formatter number. NOTE A cold reset also resets all the HP Jetdirect settings as well as the printer settings.
Troubleshooting tools and reference diagrams Repetitive image defects If the printer output has a consistent, repetitive defect, then use Table 7-9. Repetitive image defects to determine which part needs to be replaced based on the measured distance between the repetitions of the defect.
