Sharp MX-M363 black lines on self prints and copies

[TechGeek]

I have Sharp MX-M363 with black lines on self prints and copies Print Sample (2).pdf . THe PCL symbol is the self print and the other is a copy. I have replaced the LSU and the Main Charge unit no difference. There is about 30K on the PM.

Any Sugestions???

Looks like a memory issue, you will notice that the marks change to white when it reaches the Sharp logo.

I am not familiar with these machines, but first thought would be to check memory DIMM(s), then compare settings to a working machine.

If it has a memory test SIM you could try that, also.

Update. I have tried swapping out the memory in DIMM slot 2 and this made no difference. I also performed TC 67-70 which is a SRAM clear but that did nothing as well. I have some more memory coming in tomorrow to test out the memory in slot 3. I will let you know how that works out. i have also performed some self prints for TC 64-02 and the prints from the LSU-ASIC and they printed perfectly, but any self test print from the MFP-ASIC or Controller (memory) prints crappy. I have a feeling that it will be the MFP PWB.

OK i have tried swapping out all the memory and no luck so i guess is now to replacing the main board.

I realize this is an old post, but has anyone solved this issue?

do you check high voltage?
