Transfer trouble on Canon iR ADV C DX 5840

[Ingranaggio_rotto]

Good evening everyone !
I have an image transfer problem on a Canon iR ADV DX C 5840!
On the ITB group the printing is perfect, but the problem emerges in the transfer.
Problem that is present on all 4 colors!
I replaced the HV board (UN 7).
The entire transfer assembly present on the door.
Checked the mass.
ITB group replaced...
Nothing !
What do you recommend?Test di Stampa.jpg

Run that PG10 patten again but a duplex print, does the 2nd side look OK?

Did you check the values of the service label inside the front cover. Do a P Print and check the values against another machine to see if anything jumps out at you.

Good Luck!

Re: Transfer trouble on Canon iR ADV C DX 5840

weird paper issue? cold/moisture issue might do something like that.

I had faded prints on magenta and then it came back on cyan a week after.

you've probably done this already but run an autogradation before anything else.
Firmware update

and you might want to run itb img-x /mmi clear if you run out of options.

It could also be the Drum drive or Main controller
