How to fix a printer paper jam. - Computer Hope

When you removed the jammed paper, did the paper come out inone piece, if not did all the pieces that were removed make up the entire sheetof paper?
Otherwise there may be still a small piece/s of paper still in the printer,which is causing this error message.

Thank you contacting FixYa for your printer inquiry.
This error is associated with either a sheet of paper blocking the paper path or a partial piece of paper that blocks path or trips a sensor. The printer will usually throw up a error code 13.XX on the display and the XX is a number that will indicate where in the paper path this error most probably occurred. Just follow the steps for your error on the below chart.

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.

paper jam on hp laserjet

If paper is jammed, a Paper jam message will appear on the control panel display.

Follow these steps to clear the jam:

1. Gently pull any jammed paper out of the output tray or sheet feeder.
   
   
2. If the paper is stuck inside, turn off the Epson Stylus CX.
   
   
3. Open the scanner, remove the jammed paper and torn pieces, close the scanner, and turn the Epson Stylus CX back on.
   
   Note: Be sure to check the far left of the carriage area when checking for jammed paper. Paper that is jammed there may be hidden from view.

If paper jams inside the Automatic Document Feeder, clear the jam as follows:

1. Open the Automatic Document Feeder cover and remove any jammed paper.
   
   
   
   
2. If necessary, lift the document cover and remove any paper that has jammed inside.
   
   
   
   
3. Press OK to clear any messages on the display screen.

If you are getting a 'carriage jam' error as soon as you turn on your printer with no tasks in progress, then check for any piece of paper stuck in the carriage. Remove the paper carefully. If the paper tears, part of it might remain inside the paper path and damage the product.

Hi

Thanks for using FixYa. Perform the steps below in order to solve this incidence:

1. Disconnect the power cord or power supply adaptor from the rear of the HP All-in-One product.
2. Remove the paper pack remaining in the input tray.

WARNING - Do not try to remove the jammed paper sheet yet. Trying to clear a paper jam from the front of the device can damage the print mechanism. Always clear paper jams through the rear access door.

1. Open the rear access door or the two-sided printing accessory.
2. Gently pull the jammed paper sheet out of the rollers.
3. If the paper tore when it was being removed from the rollers, check the rollers and wheels for torn pieces of paper that might remain inside the device. If not all the pieces of paper are removed from the device, paper jams are likely to occur again later.
4. Replace the rear access door or the two-sided printing accessory.
5. Restart the printer to continue the current job.

Please double check if all doors, including the paper tray cover, are firmly (repeat FIRMLY !) closed. Seemingly all such are designed as precautionary measures for safe operation.

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.

For a larger image, click here. 6 Finally, reinstall all of the paper trays and press the button to try printing again.
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.

I too kept getting the front cover paper jam despite followings Oki's paper jam removal instructions and blowing out the printer with compressed air.
In my case, the paper drawer was the problem.  When you pull out the drawer there is a spring loaded piece of white plastic at the very front of the drawer.  In the center of that is a gray rubber strip.  That strip had come loose in the center and bowed out, preventing paper from exiting the paper drawer.  I manually removed the strip, clipped off a little piece from one end so that it fit back in the recessed cavity on the white plastic piece and glued it back down.
This should be applicable to all Oki c5xxx color LED printers.
