Please look at the attachments. I cleaned the contacts on the cartridges & cartridge tray. The cyan drum has scuff marks on it & will need to be replaced, but not the others that I could see. The image belt has some smears on it but nothing major. Canon's website docs had no help with this. Could the black lines be a bad cartridge or likely something else like a power supply or mainboardpages.pdf?

Re: MF8380cdw - lines, smears
hi,
The first feeling is the black cartridge,you can try exchanging it with other black cartridge.
You can try printing something in yellow only. If the printing is right there is more possibility that black cartrtidge is the problem.
All the best -
Re: MF8380cdw - lines, smears
That's what I'm thinking but if the black cart was shorted it would give a solid black copy. Not familiar with this unit but if there's an ITB/ETB it might be worthwhile to pull that our and giver a good blow job to clean out the trans rollers as well as the secondary trans roller.Comment

Re: MF8380cdw - lines, smears
Thanks for the replies! I'm leaning toward telling the customer to try a new set of genuine cartridges first (they have a set of HP CC530a-CC533a installed), then go from there. The transfer roller in the back of the machine is also contaminated so I'll have to try to find one of those. I don't have a service manual for this thing and Google searches are proving to be fruitless so it could take a while to figure this out. The image belt is below the cartridges & I haven't been able to figure out how to even take the toner tray out!
