Copier Energy Security Control

An internal clock automatically turns off and on all high-power consuming elements of a xerographic copier in accordance with a preset time schedule.

A microprocessor controlled copier includes an on/off program segment, whereby the copier turns itself on and off automatically. This is done to conserve energy and for security reasons, such as preventing unauthorized use of the copier.

The copier includes ten push buttons, numbered 0 through 9, whereby an operator normally selects the number of copies to be made. The key operator is one of only a few people who is given information as to how to place the copier in a special mode of operation, whereby the same keys are enabled to modify the on/off program segment. The key operator can then change the on/off times, as desired. Such scheduling of on/off times would include short periods of turn off, such as overnight, as well as longer periods, such as weekends, holidays and vacations.

For emergency use, certain critical users would be given an access code to be entered by way of these push buttons. This access code operates to override the on/off program and turns the copier on for a short time during one of its normally scheduled off periods.
