Help with faulty Lanier 138c

[Guest]

Hi all, I have a Lanier 138c which I believe is a Ricoh CL7000. I had the transfer belt replaced recently and it got a error code SC471. I have a donor printer, an old one I got off eBay so I stole the cam motor and little pcb board and put these in the printer hoping it would fix it. I also tried a new main board, the board that the Ethernet cable goes into from the network. It gave the error sc230-3 do I replaced the old main board and the original parts for lifting the transfer belt cam but it still shows the SC230-3 error only when printing in colour and the print comes out only in light magenta.


Help please! Is the main board damaged?

Hi, firstly unlikely to be main PCB, so put back original. Concentrate on transfer unit and sensor in rear of machine that detects belt lift. Also check condition of transfer unit, is it stiff to opperate, how clean is belt and the metal rollers it runs on. If you have spare unit try that first.

First, remove the Transfer Unit and do an Output check on the Contact Motor (SP5804-54/55/56) with the front door cheated. If that is OK, then insert the Transfer Unit and do it again and see if you observe the belt assy cam up and down. If that is observed as OK, then do an input check on the sensor (SP5803-13 bit 1). If you don't see a change of state then either the sensor is bad or the flag is not being seen by it.
As stated by coolbeer, I think the issue is something mechanical since the problem arose after the belt was replaced. Something is bent/warped/broken, either the sensor is knocked out or the rotating flag is out of sorts.
