ABSTRACT:
The invention relates to a print engine for a compact recess-mountable pagewidth printer. The printer includes a paper tray inside a housing. The print engine includes a chassis mountable within the housing next to the paper tray to define a media path co-planar with sheets of media within said paper tray. The print engine also includes a transfer roller protruding from the chassis and configured to contact the sheets of media as they are moved along the media path. A media moving mechanism moves a sheet of media through the media path. A printhead assembly having a micro-electromechanical inkjet printhead is mounted within the chassis and is configured to transfer print onto the transfer roller. The printhead assembly has a wiper and sponge arrangement for cleaning print from the transfer roller during rotation thereof.
