8546-1 LOGIC FOR COIN OPERATED OFFICE COPY MACHINE VENDER Abstract of the Disclosure In a wet cycle copier of the small tabletop mounted variety, conversion is made for vending in the absence of frequent key operator attention. Incidence of power interruption provides for a soak cycle to occur wherein the liquid toner is cycled through the machine without drum rotation. Rotation of a glass selenium coated drum against a dried and abrading liquid applicator is avoided. After the soak cycle and assuming uninterrupted power, a cleaning cycle is initiated once every 24 hours. Assuming a lack of machine use, this cleaning cycle lubricates both toner application roller and drum to assure a wet toner applicator. Dispersant replenishment is supplied from a large volume reservoir under logic control with provision made for automated machine shutdown where dispersant on demand is not supplied. Provided modes of operation include coin vending, countermechanism vending and direct owner access vending with a tamper proof interface between the provided modes. Multiple copies are provided in the countermechanism and direct owner access modes with positive memory cancel upon where these modes are charged. Coin operation includes a system of logic controlled directives and selected flashed warning with a resultant information interface to enable virtually any unskilled operator to run the machine. This same coin vending also includes priority of events logic to prevent both the retention of a coin without the machine ready to copy and to require vending once a coin is retained. In the absence of coin, vending is prevented to destroy the relatively low profit margin of the machine. Vending of two discrete sizes of paper is provided with supervision and control logic interlocks to detect both jamming of the paper and exhaustion of paper supply with automatic indication and machine switching function to the remaining available paper supply.
