Where are you getting motor from are they used are they from China if new strange you not getting a error with a laser fault.
There are adjustments you should do after replacing laser unit and or polygon motor

Oh but I was told there's no init/adjustment.
Thanks for confirming that.

Hi all

I have strange problem with my Ricoh MP 7500, poligon motor problems repeats every 100 000 copies. Change poligon motor working 100 000 copies with out problem after that problem with copy. No error code but blurry print an jaming. In the begining i cant figure out what is the problem becouse no sc code. One tehnician with lot of experiance told me to change poligon motor. After i change problem disapear, today after 2 months and 100k same problem. Put in 4th poligon motor in working ok. Already 3 motors in trash i must find what is causing polygon motor defects

Thanks
