Paper Jam I can see a little piece of paper stuck in the back of the printer but can not get to it. Usually there are paper rollers to clear a paper jam.

Turn off and back on. If the error is still there, look in different areas of the printer, somewhere there is a piece of paper stuck. Sometimes when clearing a jam, little pieces will get stuck in the rollers and you just need to search for them and remove them to clear the sensors.

Did you check the fusing section from back door? When you open the rear door you can access the fusing unit (hotest place!!!). Sometimes the paper stacks below the stripping pawls of hot roller and you can't see it easy. Look harder! Pull out the whole paper tray and check below (printer bottom) for paper sheet. Lift upper cover and remove cartridge. You will see little green lever. Lift it up! Look for piece of paper around the little black pawl (paper sensor after registration roller). Restart printer!
Good luck

Hi, If you have ever operated a printer, you have experienced a paper jam. At some point, some piece of paper has loaded off-kilter or wadded up inside the rollers. In most cases, removing the jammed paper and getting the printer working again is relatively easy.

Step By Step

1. Verify that you have a paper jam. Sometimes the printer will send you a message that there's a paper jam. Sometimes you get the message from the crinkling, squealing sound the printer makes as it jams.

2. For most consumer models there will be only one sheet of paper threading through the machine at a time and a straightforward path from the paper feed to the output tray. In that case, you will want to search visually. Look to see if there are pieces of paper sticking out where you can see them. For larger commercial printers, where the paper path is more convoluted, you will need to consult the paper jam status message for hints of where to look.

3. Remove any paper from the paper trays that you suspect might have caused the paper jam. If a sheath of paper might prevent you from getting at the jammed paper, then remove that too.

4. Most consumer printers have an access door in the front that you can open to get at the jammed paper. With laser printers there's usually a toner and drum unit that slides out for improved access. If you still can't see the jammed paper, check if there's an access hatch in the back of the printer.

5. Gently remove any crumpled paper you might find. Gently tug on any pieces of paper that may be stuck or crumpled between rollers. It's possible that yanking the paper too hard in the direction opposite the normal direction of travel could wreck the printer rotors or some other delicate part. Whenever possible, pull the jammed paper in the direction of normal motion through the printer and avoid using excessive force.

6. Avoid ripping the paper as you remove the jam. Pull the paper slowly with both hands. Any shredded piece of paper stuck in the rollers will cause yet another paper jam. While you're at it, check for foreign objects that may have caused the paper jam in the first place, such as a paperclip or a pen cap.

7. Laser printers sometimes get the paper jammed so deep in the fuser unit that you can't reach it with your fingers. In those cases you want to avoid poking at the paper with sharp metal objects. Scratching the rollers could permanently damage your print quality. Removing an accordioned paper jam may involve disassembly of the fuser unit by a trained professional.

Usually there is a little piece jambed somewhere..also look for over pushed sensors.

Paper stuck inside the HP All-in-One can cause jams or also sometimes there are some instruction that get stuck in the printer internal mechanism .
Power off the printer , unplug the power cable. Wait for 30 sec. , Replug the power cable. Power on the printer.
Check for a stuck paper or torn bits of paper.
Clear jam from the back of all-in-one
Press in the tab on the left side of the rear door to release the door. Remove the door by pulling it away from the HP All-in-One.Trying to clear a paper jam from the front of the HP All-in-One can damage the print mechanism. Always access and clear paper jams through the rear door.
Gently pull the paper out of the rollers.If the paper tears when you are removing it from the rollers, check the rollers and wheels for torn pieces of paper that might be remaining inside the device. If you do not remove all the pieces of paper from the HP All-in-One, more paper jams are likely to occur.
Replace the rear door. Gently push the door forward until it snaps into place.
Press OK to continue the current job.
Clear the jam from the automatic document feeder (ADF)
Paper can also jam in the automatic document feeder. Follow the steps below to clear a paper jam in the automatic document feeder(ADF)
Lift the cover of the automatic document feeder.
Gently pull the paper out of the rollers.
Reload and test the all-in-one
Once you have removed the jammed paper, verify that the all-in-one is still functioning properly.
Reload the all-in-one with either plain or photo paper.
Print a page from a memory card or the computer.
If you have completed all the steps listed above and are still experiencing a problem contact HP to service the product.

check to make sure there aren't little pieces of paper jammed at the ends of the roller. if you can pop out the roller easily you may find tiny pieces of paper still lodged in there

Look for little pieces of paper that get stuck in the rollers, also verify that the gears and roller didn't get misaligned when you cleared the jam.
Good Luck,

2) open the cartridge area find the paper pull slowlly forword paper direction as possible as you can and try to take out any pieces paper behide the cartridge (between paper input roller and ink cartridge

hi y'all -

you share a frustrating problem... error message but no apparent error (jam)! it's one that's common to many models of printers and the result of many different causes.

I've seen it when I've printed on cheaper paper, or different (lower) grades with odd surface finishes. the sensors get dirty, or the printer/computer 'thinks' there's paper stuck where none exists. I've opened/closed paper trays 2-3 times and rolled feed rollers around multiple times, then closed printer paper drawers only to have the 3rd time of doing the exact same steps be the time it cleared the error message.

there are often very tiny pieces of paper stuck in weird places in the paper path in printers, too. if you did have a jam before the message started, is every little scrap of the page accounted for? there are also hard to get to places to find paper scraps in larger printers, but I'm going to assume you're all talking about home printers.

here are a few general HP support links you may find helpful for future paper jam messages for this model of printer.

hope this helps a little bit for future refs. remember that using good paper helps print quality and lessens printing problems. also, when you take a stuck page out of a printer, doing so gently will help ensure little scraps of paper do not tear off paper edges and get stuck in weird spots. it some times helps to gently, manually, roll the feed rollers a full turn around in the printer, too. patience pays! -JW50
