Abstract

Bank checks 10 are normally printed with a machine-readable version of the check amount in magnetic ink characters 11. To assist automatic processing of the checks, this number often contains a series of leading 0's 12, and is required to contain field mark 13. The speed at which checks can be processed may be limited by the speed of a serial printer 14 for printing the characters 11. This speed can be increased by adding supplemental type faces 15 and 16, respectively, providing the 0 and field mark characters. Individual hammers 17 and 18 are respectively associated with the type faces 15 and 16. As a bank check 10 is stepped past print hammer 19 of the main printer 14, print wheel 20 is positioned by control circuitry 21 to present individual characters for printing.

Speed Enhancement to Check Inscriber

Bank checks 10 are normally printed with a machine-readable version of the check amount in magnetic ink characters 11. To assist automatic processing of the checks, this number often contains a series of leading 0's 12, and is required to contain field mark 13. The speed at which checks can be processed may be limited by the speed of a serial printer 14 for printing the characters 11. This speed can be increased by adding supplemental type faces 15 and 16, respectively, providing the 0 and field mark characters. Individual hammers 17 and 18 are respectively associated with the type faces 15 and 16. As a bank check 10 is stepped past print hammer 19 of the main printer 14, print wheel 20 is positioned by control circuitry 21 to present individual characters for printing. At the same time as a character is being printed by hammer 19, the check 10 may be properly positioned for the printing of a field mark 13 or a 0 12, also under the control of circuitry 21. By this method, multiple characters can be printed during each print cycle with a resultant reduction in the time required to print the entire amount field. Magnetic ink ribbon 22 is of the total release type, making it essential that fresh ribbon is available for imprinting each character. Ribbon 22 is normally stepped by control 21 in increments somewhat greater than the size of individual characters to ensure that fresh ribbon is always available. Loop 23 provides an addi...
