Abstract: A ribbon identification system detects a digitally encoded tract comprised of radially printed bands of dark and light areas positioned on a ribbon spool that fits on a media printing device. Each type and length of ribbon to be used is associated with a specific and unique digitally encoded tract. When the ribbon spool is positioned correctly on the printing device, the digitally encoded tract is detected, and the control program of the printing device sets the parameters associated with that ribbon automatically ensuring proper printing. Through the digitally encoded tract, the ribbon spool is uniquely identified so that once it has been determined by the printing device's control program that the ribbon has been depleted, that ribbon spool, if reinstalled on the same printing device at a later time, will be recognized as a depleted ribbon, and the printing device will not function.

Abstract: An ink ribbon cartridge has first and second tubes (130, 132) for holding an ink ribbon. The tubes have slots formed in each end. Spindles (140, 142, 162, 164) are attached at the ends of the tubes. The spindles have a disk portion and an end which is received by tube slots.

Abstract: An ribbon spool and associated mounting spindle for a printer incorporates multiple longitudinal ribs on the spindle that fit into multiple longitudinal slots in the spool to acquire rotational lock between the spindle and spool. A latch at the end of selected ribs interacts with a lock ridge within the spool to acquire longitudinal lock between the spindle and spool. Placing the lock ridge near one end effectively prevents the spool from being inserted from the wrong end. The latch includes a spring-loaded detent action to hold the spool in place until an operator exerts sufficient force to overcome the latch for removal and replacement of the spool. The inner cylindrical surface of the spool is also designed to work properly with conventional spring-loaded frictional force spindles. However, the reverse is not true. Due to the sloping alignment edges on the ribs of the instant spindle, conventional spools may be blocked, thus preventing improper insertion of the old spools onto the new spindles.
