ABSTRACT:
A printing machine (10) is disclosed in which printing is effected by toner being transferred from a photoconductor (18) to a receiver sheet (S) at a transfer station (46). A fuser (49) is also provided to fuse the transferred toner to the receiver sheet (S). A preferred fuser includes a heated fuser roller (70) that receives a film of a release oil (73). As a given number of supply of a receiver medium (e.g., paper) of a common size are printed and fused, the cross-track position (XTSP) at which the paper is positioned at the fuser roller (70) varies. This eliminates the release oil (73) from building up on the fuser roller (70) and transferring to subsequent larger receiver sheets (S), and reduces non-uniform wear on rollers at the fuser (49), thus reducing likelihood of image artifacts and machine contamination.
