ABSTRACT:
Circuitry for controlling the margin of a laser printer is provided which times a preset margin on a first scanline of a page at high frequency for high accuracy. Thereafter, subsequent scanlines on the page are positioned responsive to the count generated responsive to the preset margin. Hence, the laser may be directly modulated at speeds higher than the standard frequency without a reduction in the relative accuracy of the margin.
