A transaction printer includes the MICR encoding of indicia at a precise location called the amount field. In order to accomplish this, an optical sensor is provided in a transaction printer at a point-of-sale, to detect the edge of the check and stage it at a known location from the thermal, MICR print head. A clutch mechanism is used to engage the print head with a platen, and to engage two MICR read heads with the check, so that indicia can be sequentially imprinted and read within the transaction printer in a single, sequential operation.
