Error code sc322 gestetner


It's an error code for a laser synchronization error. Possible causes according to the service manual:

•Laser synchronization board connectors loose, disconnected, or
damaged
•Laser synchronization board defective
•LD drive board defective

I've also seen where toner leaks and covers the laser sync board and causes this error. Try cleaning any toner off the Sync board and see if that fixes it.

Codigo sc-322-000 copier ricoh aficio 450


sc322 is an error generally caused by a component in the laser unit. However, sometimes a faulty door switch can cause this error as well. The switches in question are the three micro-switches that change state when the right door is opened or closed. They are located on the front right side of the copier, above the fusing unit and behind a plastic cover. If you can remove these switches and test them individually, you can probably find the faulty switch. If not, you can replace all three as a set and hopefully the sc322 error will go away (once you reset the machine).

If replacing the switches do not fix the error, then the problem lies somewhere in the laser unit, possibly with the polygon mirror motor, but your best bet is to replace the whole laser assembly if you can.

Hope that helps!

Lanier LD118d showing a error sc322, how to fix


sc322 is an error with the copier's laser unit. You can pull the laser unit out and clean it up if there is toner on or in it, but more than likely either the polygon mirror motor or the laser unit as a whole assembly should be replaced.

Functional Problem SC322


Polygon mirror motor is bad. Sometimes you can put a drop of oil on the shaft, but at best is a temporary fix. You'll end up having to replace it. Good luck

SC322 on Savin 4035


Laser synchronization error. It could be just toner on the LD unit. Try cleaning and doing the Pitch adjustment. If that doesn't work , then either the unit itself is bad, or the Sync. Detector board.
***This will obviously require a tech.

Ricoh AP2600 printer gives an error message of SC322


1st Laser synchronization error signal error. The 1st Laser that turns on inside of the printer can't synchronize properly to print out documents which is why this message comes up and nothing is printing. Probably is going to need to be replaced but a qualified service tech is going to need to look at it further.
