Copier Adjustment

The replacement and/or adjustment of various copier components is enhanced by an optical aligning tool which insures that the copier's photoconductor drum is accurately positioned at a reference position prior to such replacement or adjustment.

The copier's photoconductor drum 10 carries a cam 11 which rotates with the drum and is operable to drive the copier's scanning illumination apparatus (not shown). This cam carries a reference mark 12 which, when aligned with stationary optical tool 13, insures that the drum is at a reference position.

Referring to Fig. 2, the tool 13, mounted at a fixed position within the copier, comprises a transparent plastic block carrying two aligned marks 14 and 15. These two marks eliminate parallax error when positioning the drum at its reference position. Tool 13 is preferably closely spaced to the cam, e. g., .06 inch.
