Error SC 792 on a Ricoh Aficio DSM622 copier indicates that the copier is unable to detect paper in the paper tray. This error can be caused by a variety of issues, including:

1. An issue with the paper tray or feed mechanism: Make sure that the paper tray is properly aligned and that there are no obstructions in the paper path. Check for any damaged or broken parts in the tray or feed mechanism, and replace any damaged parts as needed.
2. A problem with the paper sensor: Make sure that the paper sensor is clean and free of debris. If the sensor is dirty or obstructed, it may not be able to detect paper in the tray.
3. A software issue: Try resetting the copier and see if the error persists. If the error persists after resetting the copier, there may be a problem with the software or firmware. In this case, you may need to contact Ricoh for further assistance.

738 = Finisher shift tray lift motor error.The stack height sensor does not activate within a certain time after the shift tray lift motor turned ON.Posible cause: shift tray motor defectiove or too much load.Turn the operation switch or main power switch OFF and ON.

opne then close paper trayy

There is a sensor above the tray where the paper comes out, and that sensor has a long black actuator. Sometimes that actuator gets turned to the side, and this will cause that message to appear.

Reach above the rollers where the paper exits the copier, find the black actuator, and turn it so that it is hanging down over the tray. Once the sensor is reset that message should disappear.

Make your machine compatible with A5 paper. Go to Menu and then paper Alignment and click A5.

Sounds like it is misfeeding from the Default tray (just not getting the paper into the machine). try removing the paper from the default tray, and use another one. If it works, then the paper feed rollers are the likely cause.

sc 502 is the problem related to tray lift motor .open the backside of the machine ,almost downside u ll find one spring broken .replace tat the tray will start working.

you can change the tray setting in user mode to tray 2 and same time do not fill the tray one. same apply on print job from a computer, select tray two as default with print driver.
