    It would pay to check your pressure pad assembly. If the small metal strip on the leading edge has worked loose or displaced, this will cause either multiple feeding or can cause sheet jamming. Also if the pressure pad is badly worn (hollow where the feed wheel rubs) this will interrupt the feeding as well. If in doubt it is worth replacing it, as they are easily removed and replaced. One other thing to check.... is the lever on the feeder, set to card and not paper? This can be easily forgotten when you switch from one grade of stock to another.

Risographs being high speed printers have the separation rollers which if dirty will pull more papers in. Clean the rollers well . Isopropyl helps.

Epson dfx9000 it gives me paper jam


Hi there,
My epson printer showed a paper jam light although no paper was visible.
I discovered my son had had a paper jammed and ripped the paper out and a tiny piece was jammed inside but was not visible easily.
***NO RESPONSIBILITY ACCEPTED FOR LOSS OR DAMAGE IF YOU USE THIS SOLUTION I USED TO FIX MY PRINTER*********
i cut an A4 sized square of cardboard from a cereal packet.
I inserted this instead of paper and attempted to use the feed paper button to eject the paper jam.
This did not initially work so as i kept pressing the paper feed button i forced the cardboard into the printer in the same direction that the paper feeds whilst printing.
The cardboard pushed the tiny piece of paper out.
Turn off the printer and then turn back on - you should find the printer now works.
I also found it helpful to clean the feed path and to try and keep dust from settling in the printer.
If it is in a dusty environment it helps to keep the printer covered when not in use - you can buy plastic covers for this or any large plastic will do but does not look as aesthetically pleasing.
Hope this has helped.

Maybe you meant model RP3700 ...

These questions may help to find a solution or at least a better understanding of your problem:
Have you set the paper size right?
Is the print drum capable of the desired imaging size?

I keep getting a paper jam message but there is no paper jam. any idea????


There may be a piece of paper still stuck in the unit. If a paper jams in a printer, you should assemble the torn sheet and make sure all the pieces came out.
Forcing a jammed sheet out of a printer can damage the paper detect arm. This arm is usually near the platen (The roller the head prints against) to detect the paper as it passes.

Paper keeps jamming


try resetting by unplugging and then plugging back in, then make sure no paper is jammed in the rollers...make sure rollers are clean and they are not worn down, make sure your using the right type of paper.

Paper light will not go off


You may have a small jam or a piece of paper that is still inside the printer.  You may have to look for a smaller piece of paper.  I have had this happen to my laser printers before and it was because there was a plastic arm that is inside the printer that came loose during a paper jam and it wouldn't accept paper until I reattached the arm and then the printer would accept the paper.
