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
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.
