Abstract:
A fuser roller surface is cleaned immediately before and or after the fusing operation. The separate cleaning sequence assures that the fuser roller surface is substantially free from residual toner that has accumulated from previous fusing operation. A number of image-transfer sheets is counted, and the cleaning sequence is also optionally activated after a number of detected image-transfer sheets has reached a predetermined number.
