taskalfa 5002 ghost image.

[Gab]

First copies or are ok. But after some copies we have ghost image like in tha attached file. I swaped fusing unit from an other machine with no result.
I think is the drum or it is something else?
If i swap from an other machine what programms do i have to execute?

same as assembling from new one

Change plain paper to plain 3 in system settings.

Agree with tmaged. Not sure on the science here, because I've also seen this on larger color units (7052ci), and THAT was resolved by turning Silent Mode on. That had no effect on this model.

I have swaped the whole fusing unit with no result.
Then i swapted the whole drum unit withn no result .
I checked developer unit and it looked like that in the attached file.
is it normal? I use Katun toner.
The same problem happened and to an other 5002 i service.
If the problem is in dev unit can i execute any program to fix it?

[KYO_OEM]

NO! New DV with Kyo toner needed

[Gab]

Also i forgot (sorry) , those copies or prints that have ghost image , the image is not baked in fuser so when i rub it with my fingers toner goes away. Anmy idea?

Not to be rude, but you really should hire a technician. You've demonstrated repeatedly that you lack basic troubleshooting skills required to be successful.
Everyone here has spent way too much time trying to help you.

Looks like an ink error

Try increasing the print value in u161

Choosing thicker paper is also a way to test
