A modular inkjet printhead assembly including a plurality of printhead modules mounted on alternating sides of a central rail assembly. The rail assembly includes a beam and a rod attached to a side of the beam. The printhead modules include a jetting module having 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. Portions of the alignment tabs of the jetting module are adapted to fit within corresponding notches in the beam. Each alignment datum on the printhead modules engage with corresponding alignment features on the rail assembly to position the printhead modules such that the jetting modules are tilted away from the beam.

A method of wiping a plurality of printheads positioned in a staggered overlapping arrangement across a width of a media feed path, each printhead having a respective wiper associated therewith. The wipers for neighboring printheads are moved in opposite directions with respect to each other.

A print-head module for a single-pass inkjet printer contains a housing component with a transverse bracket which extends in the X-direction and on which a number of print heads are arranged which are adjusted positionally with respect to at least one reference position. A load-bearing frame with a supporting device is provided for supporting the load-bearing frame. The housing component is mounted on the load-bearing frame such that it swings about a pendulum axis. Furthermore, a single-pass inkjet printer has at least one print-head module of this type. The inkjet printer contains a frame construction with a support, on which the at least one print-head module is placed by use of the supporting device.

A method of wiping an inkjet printhead. The method includes the steps of: lifting a print module carrier relative to a media feed path, the print module carrier having a mounting arm bridging over a wiper carriage parked at one longitudinal end of a printhead carried by the print module carrier; and moving the wiper carriage, from its parked position below the mounting arm, longitudinally along the printhead to wipe a surface of the printhead.

A mounting apparatus for mounting a printing apparatus to a structure includes an attachment part, which is attachable to the structure, and a support member upon which a printing apparatus is supportable. The support member enables the printing apparatus to be located in a desired position along a first axis, which extends in a first direction relative to the structure, and wherein at least a part of a footprint of the support member defined in a first plane, which is substantially transverse to the first axis, overlaps at least a part of a footprint of the printing apparatus defined in a second plane, which is substantially transverse to the first axis.

A head cap covers an inkjet type recording head. The head cap includes a cap housing and a cap cover. The cap housing has a liquid storage space opened upward. The cap cover is provided along an open end of the cap housing. The cap cover has an opening through which the recording head enters and leaves.
