Message on printer Display Panel

What it means

What to do

13.XX PAPER JAM [LOCATION]

Media is jammed at the specified location (and possibly at other locations). If the message persists after all jams have been cleared, a sensor or sensor lever might be stuck or broken. For all jam messages, do the following:

1. Remove jammed print media from the specified location. Check the entire paper path for other pieces of media in the path.

2. Open and close the top cover to clear the message.

3. Check sensors and flags in the paper path for proper operation.

3.0 PAPER JAM [LOCATION]

A non-specific paper jam occurred. 1. Remove jammed media from the specified location.

2. Verify the paper tray is fully closed.

3. Inspect and/or replace the feed and separation rollers.

4. Ensure there is no obstruction in the path, such as a torn piece of paper.

5. Open and close the top cover to clear the message.

6. Check sensors and flags for proper operation.

13.1 PAPER JAM OPEN INPUT TRAYS

Paper-delay jam at paper                                feed area. 1. Ensure that paper trays are loaded and adjusted properly so media can feed from the tray. It might be necessary to reduce the stack height of media in the tray.

2. Check the input area for obstructions such as media in the path. Also check to see if the registration assembly damaged or unseated.

3. Replace any defective sensors or flags.

4. Verify the media meets the specifications.

5. Check the pickup feed and separation rollers for unusual wear. Replace as needed.

6. Rotate the media in the input tray by 180° and/or turn it over

13.10 PAPER JAM CHECK DUPLEXER

Jam at duplexer. 1. Check the duplexer and the rear area of the printer for obstructions or damage.

2. Check the duplexer for proper operation. Replace the duplexer if a sensor is defective.

13.14

For LaserJet 5si. This error is caused by a defective paper control PCA Replace paper control PCA.

13.2 PAPER JAM OPEN INPUT TRAYS

Paper-stopped jam at paper-feed area. 1. Check the input area for obstructions such as paper in the path. Also check to see if the registration assembly is damaged or if the transfer roller is out of place.

2. Replace any defective sensors or flags.

3. Ensure the media does not exceed the maximum length.

4. If multiple sheets are feeding, it might be necessary to fan the media and reduce the stack height. Also, replace separation pad.

5. Verify that the fuser is properly installed.

13.20 PAPER JAM CHECK REAR DOOR

Media stopped in the paper path during power on or when the top door was closed. 1. Remove all media in the paper path, and then open and close the top cover.

2. If the message persists after all media is removed: Check if media is jammed in the preferred area. Replace any defective sensors or flags

13.21 DOOR OPEN JAM

The top cover was open while printing. 1. Clear the jam and close the top door.

2. If the message persists, check the top door switch for proper operation.

13.5 PAPER JAM CHECK REAR DOOR

Paper-delay jam at fuser. 1. Check the transfer roller and small media belt to ensure they are operating and can feed print media.

2. Check the paper path for obstructions at the transfer roller, toner cartridge, paper feed assembly, and fuser.

3. Replace any defective sensors or flags.

4. Turn the media stack over and/ or rotate it by 180° in the input tray.

13.6 PAPER JAM CHECK REAR DOOR

Paper-stopped jam at fuser. 1. Check the paper path for obstructions at the fuser and output/delivery area.

2. Replace any defective sensors or flags.

13.99 PAPER JAM [LOCATION]

A non-specific paper jam occurred. 1. Remove jammed media from the specified location.

2. Verify the paper tray is fully closed.

3. Inspect and/or replace the feed and separation rollers.

2. Reseat the EIO card in slot [X].

41.3 UNEXPECTED PAPER SIZE

The printer detected a media size different from what it was expecting. This is typically caused if two or more sheets stick together in the printer or if the tray is not properly adjusted. 1. Reload the tray with the correct print media size.

2. Ensure that media in the tray is loaded under the front and back tabs.

3. If you are printing from tray 1, verify that the correct paper size is selected in the control panel.

4. If you are printing from tray 2, 3, or 4, verify that the three paper-size adjustments (length guide, width guide, size-selector switch) on the paper tray have been made correctly. Make sure the media is under the corner tabs.

5. After performing the actions above, press GO. The page containing the error will automatically be reprinted if jam recovery is enabled. (Or, you might want to press CANCEL JOB to clear the job from the printer’s memory.)

41.5 PRINTER ERROR
