Abstract

This disclosure is directed to a MICR (Magnetic Ink Characteri Recognition) security system which employs a Magnetic Field Strength Sensor (MFSS), and is usable on a copier or printer. Preferably, the printer or copier is of the type which uses magnetic toner and developed toner patches in the non-image regions of a photoconductive belt for process control. As shown in FIG. 1, a printer (not shown) includes a photoconductive belt 12 that is arranged in a module and is movable in the direction of arrow 17. Process control patches 27 are formed in non-image regions on the surface of the belt 12 using magnetic toner particles which generate magnetic flux lines 23.

MICR SECURITY SYSTEM IN XEROGRAPHIC PRINTERS USING AMAT OR ORGANIC BELT PHOTORECEPTORS (Cont'd)

This disclosure is directed to a MICR (Magnetic Ink Characteri Recognition) security system which employs a Magnetic Field Strength Sensor (MFSS), and is usable on a copier or printer. Preferably, the printer or copier is of the type which uses magnetic toner and developed toner patches in the non-image regions of a photoconductive belt for process control. As shown in FIG. 1, a printer (not shown) includes a photoconductive belt 12 that is arranged in a module and is movable in the direction of arrow 17. Process control patches 27 are formed in non-image regions on the surface of the belt 12 using magnetic toner particles which generate magnetic flux lines 23.

The MFSS 14 is located inside the photoconductive belt module (not shown), in contact with the undersurface 25 of the belt or photoreceptor 12, and such as to be in line with passing process control patches 27 on the belt 12....
