ABSTRACT:
A bender bar intercepts xerographic copier paper traveling from a transfer corona to the fuser rolls in a manner that compensates for sheet skew before the sheet arrives at the nip of the transfer rollers. The bender bar is fixed in position but adjustable so that copy sheets encountering the bar can have different path lengths with respect to opposite ends of the bar as encountered by the sheets. The sheet leading edges arrive at the fuser roll nip in a manner that compensates for any transfer distortion caused by factors such as axial misalignment between the fuser and input rolls, engagement of the paper by other elements associated with the transfer station paper path, or the like.
