ABSTRACT:
In a hard-copy scanner in which a set of photosensitive silicon chips are abutted to form a single page-width array of photosensors, the photosites at the critical ends of each chip are irregularly spaced, relative to the other photosites on the chip. This irregular spacing enables compensation for imprecisions in the dimensions of individual chips. The spacing principle can be applied as well to LED's or portions of ink-jet ejectors.
