摘要:
A pair of opposing rollers comprises a first roller and a second roller contacting the first roller to form a nip between the rollers through which print media passes. Because of surface irregularities in the rollers, the nip can have one or more unintended gaps at locations where the surface of the first roller separates from the surface second roller. Further, a frame holds the first roller and the second roller. A manual or automatic axis adjuster is operatively connected to the controller and the first roller. The axis adjuster changes the angle of the axis (a first axis) of the first roller relative to the axis (a second axis) of the second roller based on the gap to position the first axis in a position other than parallel to the second axis. Changing the angle of the first axis relative to the second axis reduces or eliminates the gap.
