Paper Jam light on, but no paper jam

Paper light flashing could mean several things on this machine.

There could be a paper jam in the machine. Open the front cover remove the drum and toner and look in the machine. You can also check in between the drum and toner by removing the toner from the drum. Open the back cover and look for a Jam as well.

Try putting a piece of paper in the manual feed tray which is right above the paper tray, sometimes on certain documents the margins are too big and asks to go into the manual feed slot.

The way you describe your error, it seems that there is still some residual paper stuck inside the printer that may cause subsequent paper to be mis-aligned.

Paper jams can be tricky to solve. The paper is usually stuck inside the printer mechanism so even if there is no visible paper jam, you will still get the paper jam error. Try this:

1. Turn off your printer
2. Open all trays and remove any paper stuck there
3. Locate the button to open the printer, open it and remove any paper stuck there also.
4. Repeate the above step for all buttons that you can find to access the inside of the printer
5. Close all doors and put back all trays
6. Turn on your printer

Lexmark printer have paper roller problem take printer for once service

there are sensors that tell the machine the paper is jammed us a q-tip to clean them, remove the toner cartridge and check under that area when cleaning the sensors.

There may be some tiny shard of paper stuck in some inaccessible part of your printer. Examination with a bright light source may help you find it.

try this

1. Turn off the printer.
2. Remove any paper trays. Inspect them for wrinkled or damaged paper.
3. Also open the back cover of the printer if this model has one.
4. Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
5. If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
6. If you find a piece of jammed paper, remove it by holding it with both hands and pulling firmly. The goal is to keep the paper from tearing. If several pieces are jammed together, try pulling out the middle piece first to loosen the jam.
7. If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do this step especially if the jam message comes up repeatedly without any obvious paper jam, there may be a small tear of paper inside.
8. Ones the printer is free of paper Replace the toner or ink cartridge and paper trays, close any doors you opened and turn the printer back on.
9. If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
10. see alternative if the problem is still not solved.
    

alternative :
Load a piece of thick paper, for example photo paper and press the resume button (may be diffrent button on diffrent models) a few times to the printer picks up the paper and puts it through the machine.

Try the link above. I researched your problem. It seems to me that you may either :

a) Have some small paper stuck in the rollers, or
b) need to clean your rollers,or
c) just need to reset the paper jam message.

Either way, the link above should take you right to where you need to go. If it doesn't , just go to HP.com and then their support section , type in your printer's model, and it will take you there.

Good luck !

There are several things that can cause a paper jam error, even though there is no paper stuck. The most common is that the paper pickup rollers are worn or dirty, and can't grab paper. Even though there is no paper jammed in the machine, it will show the error message. The solution is to clean the roller with alcohol and a lint-free cloth (don't use paper towels). If the roller is very worn, you will need to replace it.
