FIG. 2

Figure 1 shows a side view of a linear short conjugate gradient index lens array 10 which projects a unity image of a document 12 placed on a platen 14 onto a photoconductive surface 16. Document 12 is corner registered against a movable registration stop 18.

Figure 2 shows a side view of the same optical system when an oversize document 20 is to be copied. Magnification lens array 10 has been replaced by gradient index reduction lens array 22. To maintain the desired corner registration, stop 18 is moved to a new postion perpendicular to scan direction.
