Minolta 1250W white line defect

Archived from groups: comp.periphs.printers (More info?)

Your diagnosis is probably correct. There is an edge that keeps the
toner distribution even, and sometimes either a hard clump of toner, or
more often a piece of paper or some accumulated dust and paper fuzz gets
caught between that fixed edge and the roller.

Sometimes you can fix this by taking a business card, and gently
introducing it between the roller and that internal edge and run the
card along the length of the cartridge, and it may dislodge the cause,
although sometimes it just gets moved over to another location.
