Claim Text:
1. An electrophotographic printer, comprising: an intermediate transfer belt (ITB) module having an endless belt wrapped around a first and second roll, each roll having a shaft therethrough having first and second shaft ends; a plurality of imaging drums, each imaging drum having a first and a second shaft end; a frame having a front panel, a rear panel, a first side panel, a second side panel and a bottom panel with the first and second side panels and bottom panel attached between the front and rear panels forming a rectangular box structure, one of the rear panel and the front panel establishing a reference surface for the front, bottom, and first side and second side panels and the rear, bottom, and first side and second side panels, respectively, the front panel having an access opening therethrough and a post mounted adjacent to one of the two lower corners of the access opening, the access opening sized to allow the ITB module and the plurality of imaging drums to be received between the front and rear panels; the rear panel having a first set of openings and second set of openings aligned parallel to one another, the first set of aligned openings receiving the second shaft ends of the first and second rolls, the second set of aligned openings receiving respective second shaft ends of the plurality of the imaging drums; an access panel removably attached to the front panel, the access panel having a third and fourth set of openings corresponding to the first and second sets of openings in the rear panel, respectively, the third and fourth sets of openings being parallel to one another, the third set of aligned openings receiving the first shaft ends of the first and second rolls and establishing an ITB reference plane, the fourth set of aligned openings receiving respective first shaft ends of the plurality of the imaging drums and establishing an imaging drum reference plane parallel to the ITB reference plane, the access panel having a post opening in a lower portion thereof for rotatably receiving the post, the access panel supported by the post and a camming device; and the camming device mounted on one of the access panel and the front panel and positioned adjacent the other one of the lower corners of the access opening; wherein, in the event that the front panel and one of the first and second side panels is in a twisted position with respect to the rear panel that twists the ITB reference plane and the imaging drum reference plane causing a skew error, rotation of the camming device provides a skewing adjustment by pivoting the access panel about the post to adjust the angle of the access panel with respect to the front panel and the one of the first and second side panels to substantially correct the skew error of the ITB reference plane and the imaging drum reference plane while maintaining the mutual planarity therebetween.
