Adjustable printhead

摘要

A printhead assembly includes a printbar beam member, a printhead, and a first eccentric pin. The printbar beam member includes a beam surface and a first cavity disposed through the beam surface. The printhead includes a printhead surface and a second cavity disposed through the printhead surface. The first eccentric pin may be inserted into the first cavity and the second cavity to couple the printhead to the printbar beam member. The first eccentric pin may rotate to adjust a position of the printhead relative to the printbar beam member along a first axis along the beam surface.

主权项

1. A printhead assembly comprising first, second, third, and fourth cavities, the printhead assembly comprising:
a printbar beam member having a beam surface and the first and third cavities disposed through the beam surface; a printhead having a printhead surface and the second and fourth cavities disposed through the printhead surface; a first eccentric pin configured to insert into the first cavity and the second cavity to couple the printhead to the printbar beam member, the first eccentric pin configured to rotate to adjust a position of the printhead relative to the printbar beam member along a first axis of the beam surface; and a second eccentric pin configured to insert into the third cavity and the fourth cavity to couple the printhead to the printbar beam member, the second eccentric pin configured to rotate to adjust the position of the printhead relative to the printbar beam member along a second axis of the beam surface different than the first axis, wherein at least one of the third and fourth cavities includes a generally oval shape including an elongated section along the first axis of the beam surface, and wherein the first and second cavities include a generally circular shape configured to direct movement of the printhead relative to the printbar beam member along the first axis of the beam surface under guidance of the elongated section of the generally oval shape.
