Re: proplem in aficio 450

322 C 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.
• Poor cable 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
• LD unit defective

Above is a detailed description of your problem if the copier has had a knock there maybe a mirror out of position. remove the laser unit and open. check that the mirrors are in there correct places.

Once you have done this enter service mode by pressing the yellow clear all button type using the numeric keys 1 0 7 the hold the pink stop button down unit the screen changes. press the Copy SP mode button on the screen then turn the machine off using the switch on the left hand side wait about 5 - 10 seconds and switch on then try the copier. If the problem comes up again you will most likely have to replace the LSU (Laser Scanner Unit)


Hope this is some help please rate me

Sc 322 for RICOH AFICIO 2045

That is a LASER error code.
It can be just toner dust because that error is a bad communication between the laser synchronization detector board and the LD unit.
Sometimes the dust of toner goes to the laser and causes this error.
Try to clean the laser unit. Maybe that work

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!

Ricoh Aficio AP 2600 laser printer there is a code SC-322

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.
