Electrophotographic apparatus with multiple speed mode

A photocpying machine includes a user-operating speed selector (114) to change copy mode between "standard" (low copy speed and high copy quality) and "draft" (high copy speed and low copy quality) modes of operation. The speed selector (114) selectively provides to a CPU (110) i...

Zusammenfassung:A photocpying machine includes a user-operating speed selector (114) to change copy mode between "standard" (low copy speed and high copy quality) and "draft" (high copy speed and low copy quality) modes of operation. The speed selector (114) selectively provides to a CPU (110) instructions regarding the speed at which the photocopying machine is operated. Depending upon the speed specified by the speed selector (114), appropriate control signals (130-140) will be send from the CPU (110) to the drivers (118-128) for the major components (12, 22, 32, 26, 56, 34) of the photocopying machine (10). The drivers for these types of components are generating the appropriate signals (142-152) to directly drive their associated components. In this way, the member of photocopies may be produced per unit time and easily and greatly increased without substantially changing the copying conditions and reducing copy quality.
