Title: Electronic control arrangement for a laser printer

IPC: H04N1/46
Filed: 2000-06-14
Abstract: PURPOSE: An electronic control apparatus is provided to substantially equally maintain a plurality of write lines in a color laser printer for the entire operation of the printer. CONSTITUTION: While a printer is driving, a length of each of measurement lines is periodically determined by counting the number of PEL slice clock timing pulses generated from a PEL slice clock operating by a fixed frequency determined during a factory calibration. A length of a write line is determined by a product of the length of the measurement line and a ratio of a factory calibrated length of the write line to the length of the measurement line. After the periodic determination, the PEL slice clock timing pulse is selectively inserted to the PEL slice clock timing pulses for the write lines closest to a desired length, or selectively deleted from the PEL slice clock timing pulses, thereby increasing/decreasing the length so that all write lines are made nearly equal to the write line closest to the desired length.
