Bizhub C280 vertical lines/marks

[gmastela]

The device leaves vertical lines and marks.
We replaced the transfer belt, the roller in the unit, and the developer unit, cleaned the laser, and inspected everything, but it still leaves these marks always in the same spot.


Has anyone experienced a case like this before?
