HP Laserjet Error Codes 0 - 19 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 paperfeed 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 On NX engines this is most likely the fuser flag or the ACPM. The ACPM has a photosensor hard-wired to the back of it. 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. On a 5si, 8000, or 8100 series laserjet a Duplex Jam can be caused by a tray 2 and 3 feed assembly failure. 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. On NX engines this is an input jam. 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 prefeed 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. If still persists - replace fuser, then DC controller. 13.6 PAPER JAM CHECK REAR DOOR Paper-stopped jam at fuser. 1.

Not all of the paper jam was actually cause by paper. There are also instances that the media is the one that is jammed, causing to display a "paper jam" message.

If you can't find any jammed paper from the unit, you can try inspect the following cause..
1. Trays are loaded improperly or overfilled.
2. Tray 2 or tray 3 is removed during print job.
3. The top cover is opened during print job.
4. The media that is being used does not meet HP specifications.
5. The media that is being used is outside of the supported size range.

Also, try to tun HP toolbox.. on the Paper Jam options, click the Typical Jam Locations... to see the internal paper path and potential jammed locations.

I hope this solve your problem...thanks..

The paper tray should lift to present the paper to the feed assembly. If the paper tray does not lift then that will require attention and a fairly extensive strip down to replace either the complete tray or just the lift assembly.

Hope this helps....
Explanation of the paper jam message

A 241.09 Paper Jam message indicates that the printer thinks a sheet of paper has jammed at the front of the printer. The jammed sheet of paper is most likely to be found in one of the paper trays or under the toner cartridge.
NOTE: If you select Show areas on the operator panel, you can view one or more images to help you locate and clear the jam.

Clearing the jam
To resolve the paper jam message, you must first clear the entire paper path. To access the jam area, you will need to open one or more of the paper trays. Follow the steps in the table below to help you locate and clear the jam.
Step Action Image 1 Open the printer paper tray (tray 1), and remove any jammed media you find there. 2 Open the front cover and remove the toner cartridge. Examine the area inside the printer and remove any jammed media you find there. 3 If you have a duplex option installed, also remove the duplex access tray and remove any jammed media you find there. 4 If you were printing from an optional paper tray, such as tray 2 or tray 3, open any optional trays, starting at the top, and remove any jammed media. Pull the print media either up or down. If it does not pull easily one way, try the other way 5 If you are printing from an optional 2000-sheet feeder, open the front door. Press the elevator button (A) to lower the tray. Remove any partially fed media from the feeder.
NOTE: Make sure the stack of print media is straight and pushed all of the way into the feeder. Incorrectly loaded paper is the most common cause of paper jams from a 2000-sheet feeder option.

NOTE: You may receive a different paper jam message informing you that another sheet of paper is jammed elsewhere in the printer. If this occurs, the error code will indicate the location. Click here for a diagram showing the error code locations. The paper path will vary, depending on the paper source and number of paper feed options installed.
Remove any jammed sheets of paper you find and try printing again.

clean take up roller, chack that the printer is trying to take the paper and lifts paper up.
