Abstract

In various xerographic printers which have a Magnetic Ink Character Recognition (MICR) capability, there is a requirement to use a specific toner. Introducing an incorrect toner into the machine will result in the loss of MICR capability and a general loss of print quality. This disclosure defines a technique whereby the probability that the correct toner will be added to the machine is significantly increased.

In various xerographic printers which have a Magnetic Ink Character Recognition (MICR) capability, there is a requirement to use a specific toner. Introducing an incorrect toner into the machine will result in the loss of MICR capability and a general loss of print quality. This disclosure defines a technique whereby the probability that the correct toner will be added to the machine is significantly increased.

The concept consists of changes to two existing components within an existing MICR capable printer: the toner hopper fill cap on the machine, and the cap on the toner bottle. The color of the toner hopper fill cap will match the color of the bottle and the cap of the toner bottle to provide a visual indication of the correct toner (magnetic ink) for replenishment. The proposed toner hopper fill cap (which now has a detail which allows the cap to be removed manually) will be flush on its exposed surface, except for several small diameter holes therein. The pattern of holes in the cap is a key pattern. The top of the toner bottle will have a matching pattern, or key of protruding points which will fit into, and snap fit to, the toner hopper cap to allow removal of the machine toner hopper cap.

To add toner to the machine, the operator removes the cap from the toner bottle then the machine to...
