ABSTRACT:
A check encoder (11) for printing of full field MICR (Magnetic Ink Character Recognition) codes on checks, includes a check guide (19) and means for sensing the position of the check (25,27) in the check guide (19). A pair of fixed roller assemblies (29,31), coact with a pair of movable roller assemblies (33,35) to grip the check and move the check under the action of a stepper motor (44) to an initial known position. A hammer (87), mounted in a hammer mount (83) and activated by an electrical solenoid (91) impacts the check against successive selected characters on a font wheel (61) to print the desired MICR code. A computer program, controls the operation of the check positioning, check encoding and check moving operations. When the desired MICR code has been printed on the check, the check is moved out of the encoder (11) by means of the fixed and movable roller assemblies (29,31,33 and 35).
