CS3500i copy quality only in black

[copymech]

I have swapped the drum, developer,transfer door. Half tones and normal text dont not show defect only solid blacks. I have attached samples. Only 6k copy count.

If you print a solid page of black and crash the machine before the paper hits the drum are you getting a solid image on the drum?

Looks like laser to me. What firmware you running?

Firmware ver 3.07, I was able to fix this problem by replacing the HV pcb. We initialy thought the laser was bad, but by removing the HV out puts to the developer I was able to get a solid sky shot with out defect. This eliminated the laser in my mind. So I borrowed a HV PCB from another copier and problem solved. Thanks for the responses. Over and out.

Excuse me for pointing out the obvious, but the CS-3500i can only print in black. It's a monochrome copier. Black and white.

If the machine you have can print in color it might be a CS-3050ci or a CS-3550ci. And that will make a big difference in the diagnosis. So is it a CS-3500i, CS-3050ci, CS-3550ci, or something else?
