Sorry guys, am now learning. I started training about 4 months ago and my trainer isn't forth coming in training. And Yeah am from Ghana. Thanks for your patience and am working on it.

sorry for jumping so quick Sir.

Run a PG # 10 test print and see which color is giving you the problem. Or run single color copies and see that way also. 1 color will throw everything off when running color copies/prints.

I'd run multiple copies of PG5 on each color, since it fades after a first good print. Oh, and I'd do the PG5 on A3...

Sorry guys,i 've come across this thread just now;i hope the issue is being solved by now.

If not,i would suggest to replace the 2 RAMS on MNcont 2 pcb at the same time.

One of the RAMS is probably defective such that the image processing is only being done halfway.

Good luck.

Oh okay. It's still behaving that way. I have worked on the hops for a dozen time but it keeps coming back. Do you mean the rams on the board covering the hopper gears?

The main cont pcb2 is found in the controler box which is situated at the rear of the machine.
In fact there is only one dimm assy(2go or 1.5go).The part no is FM4-0837.
Check your service manual to see how to take out this board from the machine.It goes through a slot on the left hand side of the machine.
