Duplex inkjet printing system

摘要

A digital printing system for printing on both surfaces of a sheet of print media includes a first print engine and a second print engine in an opposed, aligned relationship with the first print engine. Each print engine includes an inkjet printhead and a transfer roller on to which ink ejected from the printhead is deposited to be applied, in turn, on an associated surface of the print media, the transfer roller of one print engine further serving as an urging device for the transfer roller of the other print engine for urging the transfer rollers into contact with their associated surfaces of the print media.
