Print engine incorporating a quartet of printhead modules arranged in pairs

摘要

A print engine is provided for a printer. The print engine includes a pair of opposed print head assemblies between which a print media path is defined and which is configured to perform duplex printing on print media fed along the print media path. Each print head assembly includes a pinch roller which can feed the print media along the print media path. Each print head assembly also includes a pair of printhead modules, in turn, each including a printhead configured to eject ink onto the pinched and fed print media. The ink is ejected onto a printing zone of the print media which is located proximal to the pinching zone of the pinch rollers.
