Question about Ricoh Aficio 450 Copier
I got the SC900 code problem fixed...and corrected the power supply issue that caused fuse #5 to blow and set the SC900 code. NOw I cannot get the paper to pull from the tray and through the photoc. or fuser. Misfeed on A and B happen each time it operates. Is there a way to set timing on the machine? or is there somthing else that I sould do?
Sounds like you may have missed a connection on the powersup unit that controls the paper feed board. No paper from trays= late jam detection @ A and or B!!!!
