Ricoh is a Japanese company that makes multifunction copiers in various sizes and abilities. Ricoh copiers are made for professional use and are more complicated than a personal or home copier. Ricoh makes copiers on a platform that is very much like a computer, so while Ricoh copiers are complicated, there are some basic troubleshooting steps you can go through on your own.
Turn off the Ricoh machine by first holding down the power button for a few seconds. If that doesn't work, you will have to find the power switch, which on Ricoh copiers is usually a narrow red switch on the side or back. If you have tried this already and it has not helped, you may want to unplug it for a few minutes once it is powered off.
Restart the copier and wait a few minutes for it to power back up completely. You should hear a beeping noise when it is ready. If you hear several beeps, that usually indicates a jam or an error. If you start back up with no problems, try your operation again.
Look for paper jams. Some small and most midsize Ricoh copiers and above will have a screen showing where the jam is located. Open the front door, paper exit area, top feeder and all paper trays to see if there is paper stuck anywhere. Sometimes there are very small pieces of paper that you can't see very well. Use an air duster to blow out all areas where paper may be jammed if the machine says it has a jam but you don't see one.
Make sure the Ricoh copier is clean. Many problems can be caused by dirty glass. Use an all-cotton cloth and non-alcoholic cleaner (often water alone is good enough) to wipe down the entire glass, including the small strip that may exist in front of the big piece of glass. This is what the feeder uses to copy or scan.
Look for error codes on the screen. If you have tried everything else and still can't fix the problem, you will need to call Ricoh. If you have an error code, this will help Ricoh diagnose the problem faster.
Don't play around inside the Ricoh copier if you don't know what you are doing -- some pieces heat up to 400 degrees or more.
