Ricoh Aficio 3006 error sc452

SC326, First of all check that the laser slitglass is still there, I've seen a couple of machines where the slitglass has been missing completely and it's been throwing up laser SCs. Remove the laser unit. Clean all the toner and dust out of it. Clean the synch sensor very carefully. If codes continue replace the LD unit. They tend to fail on these machines due to excess dusting

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.
