that mean laser unit have proplem synchro 1 can't detect do with me 2109 and 2108 via sp mode if it's not work out change it

sc 322 is the laser unit problem. the laser unit needs replacing. it can only be done by a Ricoh technician.

No calibration, but make sure the mirrors are set back correctly and that the polygon mirrors are squeaky clean. Even a fingerprint will make it go wacky.

sc322 is a Laser synchronization error:

Means that the laser synchronization signal cannot be detected by the main scan detector board.
Possible causes:
Poor connection of the interface harness which connects the laser synchronization detector board and the BiCU board.

Laser synchronization detector board out of position or is defective.
BiCU board is defective.

Unfortunately,unit needs service.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe



I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_8b8c2cd6ce148309

what is the solution

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.
