Modular printer for double-sided high-speed printing

摘要

A modular printer includes a frame. A housng in which the frame is housed has an operatively upper and an operatively lower cover and defines a print media inlet at one end between the covers and a print media outlet at an opposite end between the covers. An inlet roller assembly is mounted on the frame proximate the print media inlet for feeding a sheet of print media into the housing. A pair of opposed inkjet printhead assemblies are mounted on the frame downstream of the inlet roller assembly to define a printing zone between the printhead assemblies. The inlet roller assembly is configured to feed the sheet of print media between the printhead assemblies. An exit roller assembly is mounted on the frame proximate the print media outlet to feed the sheet of print media from the outlet. A print media conveying mechanism is positioned downstream of the printhead assemblies to convey a leading edge of the sheet of print media from the inlet roller assembly to the exit roller assembly prior to operation of the printhead assemblies.
