METHOD AND APPARATUS FOR CONTROLLING PRINTHEAD MOTION WITH A FRICTION TRACK BALL

摘要

An apparatus enables alignment of the position of a printhead independent of other printheads in a printhead assembly. The apparatus includes a printhead configured to eject ink onto an image receiving member, a plate to which the printhead can be rigidly mounted and selectively removed, and a translation carriage to which the plate is rigidly mounted. The apparatus also includes a track ball operatively coupled to two actuators for movement of the plate in an X and a roll direction relative to the translation carriage.

主权项

1. An apparatus for independently aligning printhead position in an ink printing system comprising:
a first member configured for selective mounting of the printhead; a second member to which the first member is operatively connected; a first rotational member operatively connected to the second member and positioned to extend from the second member to the first member to frictionally engage the first member; a first driver operatively connected to the first rotational member to rotate the first rotational member either to translate the first member laterally or to rotate the first member about an axis of the first rotational member.
