    Probably noise caused by image correction pcb. Check them first. Look do you see this noise, when print from film. Also can be faulty RAM module ( if used old model image processing pcb ) , or image processing pcb itself.

      Who repair has to know what should be replaced. When I repair something nobody tell what I have to replace. Have find out myself.
