1 Open the top cover, remove the print  cartridge, and then reinstall it. See Print cartridge.
2 Install a new HP print cartridge.
3 Check the connection between the dc controller PCA (location J97) and the memory chip on the print cartridge (location J600).
4 Replace the memory chip cable and contact assembly.
5 Replace the dc controller PCA. See Dc controller PCA.

13.XX.YY DUPLEX JOB INTERRUPTED For help press  alternates with 13.XX.YY DUPLEX JOB INTERRUPTED  Discard top sheet and press or 13.XX.YY DUPLEX JOB INTERRUPTED Discard top two sheets and press

A duplex job was physically interrupted as the paper was momentarily routed to the output bin during duplexing. This error is usually caused by a user who is attempting to grasp the edge of the page as it exits the top output bin during the duplexing process.
1 Press ( HELP button) for more information.
2 Remove the specified number of pages from the output bin.
3 Press (SELECT button) to continue printing.
4 Replace the duplexer.
5 Replace the dc controller PCA. See Dc controller PCA.

NOTE If JAM RECOVERY =  OFF some pages will not be reprinted. Resend the missing pages.

13.XX.YY JAM For help press
A jam exists in the media path. 1 Press ( HELP button) for detailed information about clearing the jam.
2 Press ( UP ARROW button) and (DOWN ARROW button) to step through the instructions.
3 If the media is folding into an accordion shape, make sure that the shutter on the print cartridge opens as you insert the cartridge. Replace any defective print cartridge.
4 For information about how to resolve a jam, see the specific numerical error codes in this table.
5 See Paper-path troubleshooting in this chapter.

13.01.00. or 13.03.00JAM IN TRAY x For help press   or  13.03.00 Paper JAM open input trays then open and close top cover
A page is jammed in tray X. A 13.01.00 error message indicates that the media did not arrive at the pre-feed sensor (PS102) within the specified time.
A 13.03.00 error message indicates that the media did not arrive at the top-of-page sensor (PS103) within the specified time.

NOTE The 13.01.00 error can also be caused by the failure of the paper-level sensor (PS107). If this sensor fails, the lifter motor does not rotate to lift the paper tray plate.This error can also be caused when the printer attempts to pick up media from a tray that is empty, but the paper-out sensing mechanism for that tray has failed  and the printer senses that the tray appears to be loaded.
1 Press ( HELP button) for detailed information about clearing the jam.
2 Press ( UP ARROW button) and (DOWN ARROW button) to step through the instructions.
3 Check that the paper-out sensor in the specified tray is functioning correctly.
4 Clean the pickup roller. If it is worn or damaged, replace it.
5 Clean the feed and separation rollers. If any of the rollers are worn or damaged, replace them (always replace both rollers at the same time).
6 Verify that the pre-feed sensor (PS102) is installed correctly. See Paper-feed assembly.

13.01.00. or 13.03.00JAM IN TRAY x
For help press
or
13.03.00
Paper JAM open input trays then open
and close top cover
A page is jammed in tray X. 

A 13.01.00 error message indicates that the media did not arrive at the pre-feed sensor (PS102) within the specified time.
A 13.03.00 error message indicates that the media did not arrive at the top-of-page sensor (PS103) within the specified time. If the actions listed above do not resolve
the issue, continue with the following:

1 Open and close the specified tray while watching the control-panel display. A short delay should occur between when the tray closes and the tray-size message appears on the control-panel
display. If there is no delay and you do not hear the tray-lift motor lift the tray plate into place, replace the stack position sensor (PS107, PS802, or SR2) in the tray. See Printer switches and sensors, 500-sheet feeder switches, sensors, solenoids, and PCAs, or 1,500-sheet feeder switches, sensors, solenoids, and PCAs.
2 Replace the tray X pickup solenoid.
3 Replace the tray 1 paper-pickup assembly. See Tray 1 paper-pickup assembly .

NOTE The 13.01.00 error can also be caused by the failure of the paper-level sensor (PS107). If this sensor fails, the lifter motor does not rotate to lift the paper tray plate. 
This error can also be caused when the printer attempts to pick up media from a tray that is empty, but the paper-out sensing mechanism for that tray has failed and the printer senses that the tray appears to be loaded.
4 Replace the paper-feed assembly. See Paper-feed assembly.
5 Verify that the top-of-page sensor (PS103) is operating correctly and that the sensor flag can freely move. Replace the sensor if it is not Operating correctly. See Printer switches and sensors.
6 Replace the dc controller PCA. See Dc controller PCA.

A 13.20.00 error message indicates that the printer power was turned on or that the printer attempted to initialize while the prefeed sensor (PS102), the top-of-page sensor (PS103) or the fuser delivery sensor (PS108) was detecting media.
A 13.21.00 error message indicates that the top-cover-open switch (SW101) was activated while a print job was printing (the top cover was opened or the switch is defective).
1 Press ( HELP button) for detailed information about clearing the jam.
