C280 Cyan problem

[allan]

i have a C280 that only develops only half an image in main scan direction. Here is a list of components i replaced in order to no avail.
IU, Dev tank, HV board, Transfer belt, Laser, Drive section, OACB, MFPB, Wiring brkts and wiring. Please if anyone knows what can cause this please let know.
This machine has got me dumb struck. i did check the mylars between the transfer belt an IU's.

laser units are fragile on these - I've had to pull brand new ones apart to reseat the mirrors correctly after being bashed around in transit.

Also make sure the glass cleaning device isnt detached
