A method and apparatus for selectable duplex and simplex printing of sheet or web media has a selection mechanism for switching between the printing modes. The selection mechanism includes guides which determine whether a medium follows a long transport path or a short transport path between an input zone and an output zone. In the first transport path, the medium is transported past a first inkjet printhead for printing onto a surface of the medium. In the second transport path, the medium is transported past a second inkjet printhead for printing onto one surface of the medium, then turned and transported past the first inkjet printhead for printing onto the other surface of the medium.

Inkjet printer with selectable simplex and duplex printing

Inkjet printing apparatus has a printhead mounted on a printer carriage and a maintenance assembly mounted on a maintenance carriage. Media are transported to the printhead for printing. To prepare for maintenance operations, a printer drive unit drives the printhead carriage between a printing position and a printer parked position where it is spaced from the printhead. A maintenance drive unit drives the maintenance assembly between a maintenance assembly and a position next to the printhead where it occupies the space vacated by the printhead.
