Abstract

Proposed is a software modification for electrophotographic printing machines that activates the copy quality (CQ) adjustment during the machine warm-up period. The modification places the machine in a state of print making readiness when the fuser is available for operation. This reduces the first copy out time and provides a "user friendly" feature.

Proposed is a software modification for electrophotographic printing machines that activates the copy quality (CQ) adjustment during the machine warm-up period. The modification places the machine in a state of print making readiness when the fuser is available for operation. This reduces the first copy out time and provides a "user friendly" feature.

Referring to Figure 1, there is shown a flowchart for a fixed delayed convergence implementation. After power is applied to the machine at step 10, the warm up sequence at 12 is parallel processed with the convergence procedure at step 16. The delay, at step 16, is programmed so that the convergence procedure and the warm-up procedure terminate simultaneously. Thereafter, the machine announces its status, at step 18, by communicating a message via a visual display or by a synthesized voice output. As sh...
