Abstract:
1. A print engine for a compact recess-mountable pagewidth printer having a paper tray inside a housing, said print engine comprising: a chassis mounted within the housing next to the paper tray to define a media path co-planar with sheets of media within said paper tray, the chassis being mounted on the same side of the media path as the paper tray; a transfer roller mounted in the chassis and protruding from the chassis into the media path to contact sheets of media in the media path; a media moving mechanism for moving a sheet of media along the media path, the media moving mechanism including a pick-up roller provided on a side of the media path opposite the chassis and the paper tray; and a printhead assembly having a micro-electromechanical inkjet printhead mounted within the chassis and configured to print an image onto the transfer roller, the printhead assembly having a wiper and sponge arrangement for cleaning print from the transfer roller during rotation thereof, wherein the transfer roller transfers the image as printed thereon by the printhead onto the sheet of media along the media path, and the printhead is adapted to park against the transfer roller, thereby sealing the printhead with the transfer roller to prevent drying of the printhead.
