Hi, i have a machine ricoh aficio 1035 giving a code sc-322, i serviced the the laser unit error gone but now machine giving error sc 326, i need a solution without changing laser unit thnx?

this is a laser unit problem.check laser connections clean the laser unit.

hii dear 322 means synchro1 not detected signal that go to sp mode yellow cancel and put 107 and hold on red cancel 3 seconds yo will see copy sp in asquar then put 2109and# and 2108and# and close machine and open if it's not work out try to clean mirrors in laser unit ok

clean laser unit or replace it

sc326 is a laser synchronization error. The problem is usually caused by the laser sync detection board or the LD unit.

On most Ricoh models, SC-322 is a problem with the laser unit. If you have a service contract, have your technician take a look at the printer. Otherwise, you can either have a local Ricoh tech give you a repair estimate or buy a new printer.

On rare occasions you can turn the printer off and turn it back on and the code will be cleared, but most of the time this is a serious error that requires a service technician.

Error Code SC322:
1st laser synchronization error

The 1st laser synchronization signal cannot be detected by the main scan synchronization detector board even if the laser diodes are activated.

Possible Causes:
+ Poor I/F harness connection between the laser synchronization detector board and the LD unit.
+ Laser synchronization detector board out of position and angle of reflection not correct
+ Laser synchronization detector board defective LD unit defective

Not sure what your expertise is on this, but unless you know how to service the machine yourself, this one is going to require a service call...

There have been instances where toner drops onto the LD Unit and creates problems like this. About a month ago I replaced the Laser Synch. Detector Board in a 1045 for this exact problem and error code.

I'd start by cleaning up any toner on the LD unit, and re-seating all the electrical connectors on the laser unit. If that doesn't clear things up, it's probably one of two things, the LD Unit or the Synch. Board. I'd lean more towards the Synch. Board myself, but you never know...

LD unit, or BICU board....Do LD pitch adjustment -both 400 and 600dpi

sometimes the plastic of the laser is turned by the heat proves to relax and to fit the screw that holds the laser unit that is of the side of the drum while it raises a millimeter with a screwdriver, this sometimes works.
Verifies that the glasses and mirrors well be positioned correctly.

Never heard of this happening to five machines before.  Check the connections in the laser unit.

SC 322 is a laser diode problem. It will require service.
