Error SC326 on aficio 1045

It's a laser error code, service call required

326 error in laser unit . check ld conection and reset yourmachin

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.

this number belong to synchro2 is not detect replace laser unit

you proplem with laser unit sychro2 not detected try to clean mirrors inside laser and be carful if it's not work out change it and go to programmes and put 2-109 and 2-108

SC326 is a laser synch detect error. The jamming is probably just because of the code popping up and the machine shutting down. 9 times out of 10 the cause of an SC326 is toner dust buildup on the laser optics. It is either that or possibly a laser unit (LD Unit) failure. The power to the LD unit flows thru the front door switches and I have seen those go bad and cut or reduce power to the LD unit which will cause the same code. I would get a Ricoh tech out to clean the laser optics. This is especially true if you open the fron door and there is toner dusting around the toner cartridge/DV unit area.
Good Luck and Thank You for using Fixya.

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

Laser Synchronization Error(1 & 2)(sc322 & sc326)

· Laser synchronization detector board out of position
· Laser synchronization detector board defective
Also check if any cables are loose and also if the laser unit is dirty.-Clean 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.

Probably cleaning to the mirrors and glasses inside the laser the problem can be solved, but this is a complicated work if you are not technician I recommend to him that she asks for technical service. Also a bad connection of the flat cable can cause this problem. The detector of synchronism defective also since code SC326 is a fault of detection of synchronism.
