Print engine for a modular commercial printer

摘要

A print engine for a printer includes a support structure. A pair of drive rollers is rotatably mounted on the support structure and is configured to define a gripping zone into which a sheet of print medium can be fed to be gripped between the rollers. The drive rollers define a feed zone between the gripping zone and a tangential plane common to both drive rollers through which the sheet of print medium passes. The print engine has at least one print head assembly that includes at least one print head chip carrier that is mounted on the support structure and which is configured to extend into the feed zone. At least one print head chip is mounted on each print head carrier to be in an operative position with respect to the sheet of print medium in the feed zone.
