Abstract
Timing pulses (TP) are generated in response to incremental rotation of a photoconductive drum (40). The pulses (TP) are counted by a presettable counter (10) and decoded to produce control signals (STEP.sub.n) for scanning of an original document, sheet feed and other operations. When the count in the counter (10) reaches a certain value, the counter (10) is preset to a value depending on the paper size. A single control program is provided having a sequence of fixed program steps which are executed in response to respective counts in the counter (10). The smaller paper lengths are accommodated by programably presetting the counter (10) in such a manner as to skip unnecessary count sequences.
