Error Message - Paper Jam

I had a paper jam. I removed the offending sheet of paper which unfortunately tore into 4 pieces as it came out. Upon piecing the sheet of paper back together - there is a small piece missing. I've checked the printer thoroughly - nothing can be found!

I now have an error message stating Clear paper jam then press OK. & a diagram showing the rear of the printer. I've checked the printer thoroughly several times but the message will not clear.

I then tried to turn the machine off. The on-off button then starts blinking and will not shut off and the screen says it is shutting down but it doesn't. I turned it off by shutting down my PC, then rebooting - I now have a message which states: "To avoid damage use the on button to shut down the printer. It then makes loud clicking
noises and reverts to back to the paper jam message.

Anyone experienced this problem & if so - how did you solve it

I borrowed this from a different site, and I have no idea who originally posted it, but I followed these steps and found paper in the drive gears on the right side (left from the back). 
------ SOLVING THAT "PAPER JAM" ERROR ------
REFER TO THE USER SUBMITTED PHOTO FOR GRAPHICAL NOTES AT THE other HP Officejet Pro L7780 Color All-in-One Printer/Fax/Scanner/Copier (C8192A#ABA)Amazon 7780 Product Page here: 


Required Tools:
(2) Medium sized paper clips

Preferable Tools:
(1) Pair of pliers with rubber grips
(1) Edged tool such as wall paper knife, metal pick or toothpick to clean out gear teeth. (I used a toothbrush...)


This fix applies to paper jams the device believes are in the rear duplexer and often occurs after a real jam that has shredded the paper inside the mechanism.

Despite the fact you've carefully cleaned out all the visible paper from inside with the cover open, paper can jam the gears used to drive the rear rollers and even the tiniest amount of shred prevents operation resulting in the impossible Paper Jam error.

HP Tech Support online and on the phone don't troubleshoot it past "clear the paper from the device than try again please" b.s.

After removing the duplexer, grip any of the four rubber rollers and attempt to rotate in either direction, if they don't move freely with little effort, then continue with these instructions.

Begin:

1. Take the first paper clip and contact the lower two brass rectangles, this fools the device into believing the duplexer is installed, keep the contacts bridged (don't remove your hand or the paper clip until Step 4.) THERE IS NO ELECTROCUTION RISK.
2. Press the "OK" button on the control panel to pretend the paper jam is cleared. 
3. CAREFULLY OBSERVE THE pair of white gears on the left, if they seem to clutch, stall, skip or freeze then you have paper shards which are causing the jam. 
4. Using a firmer grip or pliers, grip the furthest left rubber roller and rotate in either direction , the gears should rotate with your efforts and look for shards of paper in the gear teeth.
5. Use the paper clip, toothpick or any appropriate edged tool to clear the shards.

Bridge the lower contacts again and observe if the gears rotate freely, if so then you've cleared the insidious jam should be able to print until the next error..."

Canon printer paper jam


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.

The paper had jammed when i was printing, i removed the jammed paper and tried printing again. however, the display on the printer shows paper jammed. what now?


You may have left behind a tiny piece of paper that tore off your sheet as you removed it. Make sure that you have all of the jammed paper and look carefully for any remnants inside. Look to see if the printer did not pick up a second sheet that is still in the system somewhere.

HP j5780 printer sends "paper jam" message AFTER it prints one page. there is no apparent jam in all the places I have looked. I am in need of a repair manual (not an owners manual).


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.

Follow the steps for fix HP Printer Carriage Jam

Turn off the printer and open it to see where the paper is stuck.
Manually move the carriage toward the opposite side.
Check the paper path and remove any piece of paper or any other object that is stuck in the path.
Reconnect the power cord and turn on the printer.

Paper jamed


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.

Paper is torn at fuser area of Dell 1125 and cannot remove


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.

Paper jam!!


Please perform the below steps.

1. Switch off the printer and disconnect the power supply. Allow any residual charge inside the all-in-one printer to dissipate before putting your hands or any metal tools inside the chassis.

2.
Pin down the exact location of the jam. The 3 hot spots for a jam are before a sheet completely leaves the paper tray, anywhere between the feed tray and print carriage or between the print carriage and output tray.

3.
Take off the front paper tray if the sheet jammed while still in the front area of the printer. If here, you should be able to see most of the paper.

4.
Pull the sheet with both hands and steady pressure. Do not tug as you might rip the paper, leaving a piece deeper inside the machine.

5.
Open the back panel to reach paper jammed between the feed-tray area and print carriage. Carefully remove the jammed paper.
put the cables back and switch on

OKI C5100 printer repeated jams. Usually flashing the code of "380: paper jam" as the message.


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.
