1 Resist roller (Drive) The Resist Roller (Drive) synchronizes the paper timing to the image on the Transfer Belt. A
buckle is created to eliminate any skew in the paper. The paper is then driven to the Transfer
section where the image is correctly timed for transfer onto the paper.
2 Resist roller (Idle) The Resist Roller (Idle) puts pressure on the back side of the paper allowing the Drive roller
to move the paper to the transfer section after proper buckle timing has occurred.
