Abstract

Methods and apparatus wherein a removeable supplemental controller is used to adapt a paper processing system to changes in functionality, particularly when the processing system comprises a printer, and the supplemental controller is a MICR flash device, and the changes in functionality relate to accepting input from an electromechanical keylock added to the printer, and to sensing the presence of a MICR cartridge within the printer.

Claims

1. A printing system, comprising:

a printer having a flash memory device connector;

a MICR sensor for sensing when MICR toner is in the printer;

a manual keylock selector for selecting printing options; and

a controller flash memory device adapted to be connected to the printer by the flash memory device connector, the controller flash memory device containing an interface for the MICR sensor, an interface for the manual keylock selector, a controller, and a memory, the manual keylock selector having multiple separate positions, and the controller flash memory device adapted to perform any combination of two or more of the following functions;

prevent any MICR job from printing while the keylock is in a first of multiple positions,

allow any MICR jobs to print while in a second of multiple positions,

allow no job to print while in a third of multiple positions, and

allow any job to print while in a fourth of multiple positions;

the controller flash memory device adapted to select the function to perform at a given position in time based at least in part on the current position of the keylock.
