Dark lines on end of fuser on all the color drum cartridges. That was why I changed them out in the first place,
but now they are doing it again?????
On first thought, I was thinking that it might be something with the transfer belt.
The black lines, are they just black toner lines or actual groves ?
On of the users has a Workcentre 6515 DN network printer that was printing dark line on left side of page. I changed out all the color drum cartridge, because they all had a line on the fuser roller, but now it is doing the same thing. I checked the new cartridges and the line is on the new ones now, what could be causing this. I have checked the rollers but cannot find any damage.
