PRINTHEAD ASSEMBLY WITH REMOVABLE JETTING MODULE

摘要

An inkjet printhead assembly includes a rail assembly and a removable jetting module. The rail assembly includes a beam and a rod attached to the beam. A printhead module includes the jetting module and a mounting assembly. The jetting module includes an array of nozzles, a first alignment tab having a first alignment datum and a second alignment datum, a second alignment tab having a third alignment datum and a fourth alignment datum, a rotational alignment feature including a fifth alignment datum, and a cross-track alignment feature including a sixth alignment datum. The mounting assembly includes a similar set of alignment features. Portions of the alignment tabs of the jetting module and the mounting assembly are adapted to fit within corresponding notches in the beam and engage with the rod. A jetting module clamping mechanism applies a force to the jetting module causing it to engage with the rail assembly.
