Did you ever find out what was causing the problem? I ran into this the other day too.

Let us know which parts have been replaced. It sounds like a cleaning blade issue, but we need more information.

Sample attached.

Since the ghost image only appears when printing in color, it would suggest the black drum cleaning blade is ok. At least that is what I'm thinking.

I didn't have time to do much easter egg hunting when I was at the customers office. There was another machine that needed a toner clutch replaced, so it was after 5pm when I started looking into this. So I had to go.

I'll be back there today and see if I can figure it out.

Thanks

looks like cleaning blade. hard to tell what one from the sample.

I've had a couple of aries do this (both 3610s i think) In both cases i replaced the drum drive frame cfrm-1482ds53. going in the job looks a lot worse than it is.

I'm assuming that is not on the original? Seems like blade possibly hot roller if not. I find if you take the blade out and clean it off with a rag it can take care of weird issues. If its burnt to hell though probably just needs to be replaced. I guess I would check the transfer screw / blade as well.

You ran Sim 50-22 and 50-28 46-74 ?

I went back to the machine yesterday and localized the symptoms. The ghost image shows only when printing cyan.
Single color prints in black, yellow, and magenta are all clean. Single color cyan has the ghost image in black.

Full color print of test sheet shows the ghost image of the cyan area of the test page.

I swapped the cyan drum unit with magenta and there was no change. I swapped the black drum unit with yellow and there was no change.

According to the tech manual, the transfer belt solenoids have 3 conditions. All on, all off, and black on only.
So in single color mode all transfer solenoids are engaged.

I visually inspected the drum connections for the bias terminals, drive couplings, and erase LEDs. As far as I could tell the all appeared to be normal. I also removed the transfer belt cleaning blade and wiped it off. Visual inspection of the transfer belt, all looked normal.

At this point I'm going to flash the firmware, cross my fingers, and then if needed try replacing the transfer unit.

Not yet, I will try them when I return to update the firmware.

We are experiencing the exact same problem, all devs, drums and main charges have been replaced and setup (24-4, 5, 25-02, 50-22, 46-6 etc
The primary and secondary transfers have been swapped, so to has the fuser unit

We are now thinking LSU

I have not been back to the machine yet. I called Sharp tech support, they just said it must be a cleaning blade and acted annoyed. I ordered a transfer belt and it came today.

I'm going back with the transfer belt and do more troubleshooting. Since it didn't help in your case, I'm not expecting it to work either. But I just want to rule it out before going further. Also the transfer belt being the problem does not line up with the symptoms anyway.

My biggest concern is why there is a partial black image on a single (cyan) color print. The black partial image would have to be on the black drum and transfer to the transfer belt.

The LSU crossed my mind. I was hoping there would be a connection with the cyan/black in the LSU. But the tech manual says it uses 2 LEDs per color. And each color has it's own set of LEDs. So the LSU is not using the same LEDs for Cyan/Black.

Good luck and God speed. I'll let you know if I find out anything.

You are right . Magnetic Roller worn out also can cause this trouble.
