Bad power supply, service needed

Bad power supply call your service provider

That is a "second laser synchronization error". Try this: Hit the yellow button, press numbers 1, then 0, then 7, then hit the orange key. When it goes into SP mode, turn off the copier and unplug it. Wait 15 seconds then plug back in and turn on. If that does not fix it then you need to call a tech to service the machine.

Without the model i think it is difficult to help you any way.

sc 542 is the fuser error code. please check with a ricoh tech to fix it.

The SC 326 is -- 2nd laser synchronization error. Meaning, the 2nd laser synchronization signal cannot be detected by the main scan synchronization detector board even if the laser diodes are activated.

Basically your polygonal mirror motor unit is bad and needs to be replaced. You can replace the whole laser unit but that is expensive. When you replace the PMM unit, do so in a still air area -- as to not get anything in the unit. When you get the PMM unit -- contact me and I can walk you through the steps to replace.


The SC 452 is --- Transfer Belt Mark Detection Error. Once you fix the SC 326 error this one should be fixed also.
