AF-700 SC-120

[Polo-022]

It makes a single copy and it pops out this code...I have already replaced scan motor, MCU PWB, Home position sensor, without any success. Optics alignment has been checked, cable tension also, setscrews are new, rails are clean and lubricated with light oil, scan drive belt in good condition, what am i missing guys??? ( I think i have to mention that 7K copies before i replaced both setscrews for an SC-124 code)
Thanks for any input!!

If you replaced the screw due to a scanner crash, check the mirrors on the edges to see if they are chipped.
