Abstract
A duplexing unit for reversing an orientation of a sheet in an imaging apparatus, the duplexing unit includes: an outer member including an inner surface; an inner member that is housed within the outer member, the inner member including an outer surface, wherein a duplexing path is provided between the inner surface of the outer member and the outer surface of the inner member, and wherein the inner surface of the outer member has a kinetic coefficient of friction that is between 0.05 and 0.30.
Claims22
A duplexing unit for reversing an orientation of a sheet in an imaging apparatus, the duplexing unit comprising:
- an outer member including an inner surface;
- an inner member that is housed within the outer member,
- the inner member including an outer surface, wherein a duplexing path is provided between the inner surface of the outer member and the outer surface of the inner member, and wherein the inner surface of the outer member has a kinetic coefficient of friction that is between 0.05 and 0.30.
A printer configured to print in a duplex mode, the printer comprising:
- a media input holder;
- a pick roller for advancing a sheet of recording medium from the media input holder;
- a feed roller for advancing the sheet of recording medium toward a print region when rotating in a forward direction;
- and
- a duplexing unit for reversing an orientation of the sheet of recording medium, the duplexing unit comprising:
- an outer member including an inner surface;
- an inner member that is housed within the outer member, the inner member including an outer surface, wherein a duplexing path is provided between the inner surface of the outer member and the outer surface of the inner member, and wherein the inner surface of the outer member has a kinetic coefficient of friction that is between 0.05 and 0.30.
The printer of claim 22 further comprising a motor for providing rotational power to the pick roller, the feed roller and the duplexing roller.
