Abstract

A cartridge for insertion into a digital printing device, preferably, a drop-on-demand inkjet printing device, has a casing that houses a supply of cut sheet media and a media transport mechanism. It also has a drive engagement formation connected to the media transport mechanism; wherein, the supply of print media and the media transport mechanism are enclosed by the casing; and the drive engagement formation is partially external to the casing and positioned such that it engages a powered drive in the printing device upon insertion of the cartridge. By incorporating the media transport mechanism into the cartridge, the casing can be fully enclosed apart from the media exit slot. This minimizes any contamination of the sheets because the exit slot is the only opening.

Claims2

Dependent claims

A cartridge for a printing device, said cartridge comprising:

a casing housing a supply of cut sheet print media and a media transport mechanism for picking up individual sheets of the print media and feeding the individual sheets through an exit slot in the casing;
a drive engagement formation connected to the media transport mechanism;
wherein,
the supply of print media and the media transport mechanism are enclosed by the casing;
and the drive engagement formation is partially external to the casing and positioned such that the drive engagement formation engages a powered drive in the printing device upon insertion of the cartridge, and
wherein the drive engagement formation has a drive shaft extending into the casing through an aperture that forms a bearing point for rotatably mounting the drive shaft, and the media transport mechanism has at least one roller mounted on the drive shaft, and
