Konica 7075 Copies Lighter Toward the front of the machine

[arcdigi]

My copies are lighter near the bottom 1 1/2 inches of the sheets..What could be causing this. I have swapped out the developer unit, the charging unit, the drum, and cleaned the transfer/sep unit..

I forgot to mention this is the same through printing or copying

Verify that the Dust Proof Glass is clean. Probably the laser beam isn't "getting" on the drum in that area.

Its usually soilage of the polygon mirror in the write unit. Take out the write unit, remove the units top cover and gently clean the faces on the rotating mirror. This should sort it

All the most probable causes were already mentioned, but if all else fails, check if the machine is level.
