We picked up a used 3511 with 31K copies.
the copy quality is really unstable. It\'s kind of hard to describe
the cq but it\'s washed out on rear side of the machine consistantly.
Now sometimes the rest of the copy looks good, sometimes
the front side washes out as well and othertimes the center
washes out and the front and rear fade out completely.
It does this when you copy or print and the image is faded
on the drum as well, so that eliminates scanner and transfer.
i have another 3511 in the shop so I\'ve been swappimg parts.
here is what has been replaced:
developer unit, process unit, laser, HV power supply, main pcb,
controller pcb, mother board.
any ideas? Tech support sure didn\'t have any.
Any help would be appreciated.
