Abstract: A printer includes: a media support defining a media feed path; and a pagewide printing unit for printing onto media fed along the media feed path. The printing unit includes: a maintenance chassis fixedly positioned over the media feed path, the maintenance chassis having a maintenance module fixedly mounted thereto; a print bar chassis movably mounted on the maintenance chassis, the print bar chassis including a print module having a printhead; and a lift mechanism for raising and lowering the print bar chassis relative to the maintenance chassis between a maintenance position a printing position. The printhead extends and retracts through a space defined by the maintenance module in the printing and maintenance positions, respectively.

Abstract: A printer includes: a printhead assembly (9) having a print zone (5) and a belt assembly for feeding print media (22) past the print zone in a media feed direction. The belt assembly includes: an endless belt (1) tensioned between a first roller (3) upstream of the print zone and a second roller (7) downstream of the print zone; a drive mechanism (24) for moving the endless belt in the media feed direction; and a fixed platen (20) positioned in the print zone. The endless belt is guided around and below the fixed platen.
