ABSTRACT:
Method and apparatus for operating a copier-duplicator which initially produces a master and thereafter produces copies from the master. The copier-duplicator is enabled upon receipt of a valid access code to begin producing the master and copies thereof. Counts of the number of masters and copies are accumulated. The copy count is compared against a minimum amount and each time a new master is made and if the number of copies produced is less than said minimum, a violation count is stored together with its associated access code. If the copier-duplicator is in a lock-out mode, access is denied to the access code having a violation. If in a flag mode, access to the machine is permitted even if a violation code is present. However, there is a capability of displaying all of those access codes having a violation associated therewith. It is further possible to prevent access to the copier-duplicator in the event that the number of copies or masters exceeds a maximum permissible amount.
