Media cartridge for inkjet printhead

摘要

A media cartridge for supplying a roll print media to a printhead via a drive roller assembly, wherein at least one of the rollers in the assembly is sized and positioned so that the media wraps around its surface to remove residual curl in the media caused by storage in a roll. Providing the media in a roll allows the cartridge to be small and compact. However, the curl imparted to the media from being stored as a roll can interfere with printing when the media substrate passes the printhead. Using a de-curling roller within the drive rollers can straighten the media enough for flat engagement with the platen opposite the printhead.
