INKJET MODULE HAVING MAXIMALLY SPACED DATUMS FOR CONTROLLING PRINTHEAD HEIGHT

摘要

An integrated inkjet module includes: a support chassis configured for fixedly mounting on a media feed chassis; a maintenance chassis mounted on the support chassis; and a print bar chassis liftably mounted on the maintenance chassis, the print bar chassis having one or more printheads mounted thereon. The print bar chassis includes datum pins maximally spaced apart at each corner thereof, with each datum pin engaging with a complementary datum surface of the support chassis to control a separation between the printheads and a media feed path during printing.
