Ricoh aficio 1515 Keeps displaying a paper jam in the document feeder eventhough paper path is clear

Every time there is paper jam, the printer knows the job is not completed and hence tries to re-print after the paper is removed and cover is shut.

Clear the print job from computer.
Power off the printer and Clear the paper jam (if any)
I would try to use different tray. The paper pickup roller in one path may be worn out.
eg Sheet feeder or multipurpose tray.
Load paper in new tray
Set the application to use new tray

Ensure you sue the right thickness (gsm) of the paper. Quality of paper is crucial. Too thin; too thick can affect functioning.

if it is in warranty , send back , and they will solve that problem.

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.

when you press the printer btn on the copier what does it say in the window ?

cleane sensors in paper path

Make sure the paper that is in the drawer matches the orientation and size indicated on thje Op Panel Display, If NOT, MAKE IT MATCH.

There is not a reset for jams in service mode. Did you open and close all the doors and make sure they are closed all the way. Most likely you still have a small piece of paper left some where in the paper path or you may have a broken sensor flag.

Take a little soap and a little water and clean the gray feed tire that is located in the document feeder. Check for any paper obstructions. If the machine has had a lot of prints I would replace the feed tire.

Does it also do this while printing?

Does it do if while using the auto document feeder and the glass or just one of the two?

Does the light come on inside when it scans?
