hello,
This is tech sandvitch. So sorry for you. The paper jam problem come from many part of the machine but some thing to check: Does the paper get well inside the machine before stop under the drum? If it is so there is a sensor called paper feed sensor. If that sensor is not functioning well (most of the time it is dirty by the dust)it can cause paper jam.I have the RN series manual as a book.
But if the paper is not getting well into the machine check therefore the scraper pad and pick up rollers
i'm trying to add the localisation of mentioned part that i scanned but it doesn't work give me an appoint ment on yahoo messenger so that online ican direct you to solve that problem.
Thanks everybody for the help you always giv those in need.

We're having the same issue with an RZ990. We actually replaced the sensors and cover and are still receiving the error code. Is it time to move on to the Mech Control PCB?

Hello,
You should not touch tHe any pcb yet but u have to test all the sensors that control the paper.
612 for paper ejection FG sensor
600 paper detection sensor............
if they r responding well and you still hav the problem u hav to check the paper feeding mechanism n check the timing. you shall also check the separation mechanism that release paper from the drum
