<p>PROBLEM TO BE SOLVED: To solve the problem of a system for regulating the delay time relative jitter of a print clock using a measuring instrument, e.g. a synchroscope, that adjustment is required for each printer. SOLUTION: The control method for laser printer performing automatic print clock relative jitter regulation of a two beam laser beam printer controller is arranged to perform appropriate relative jitter regulation of a print clock by comparing the difference among respective print clock signals passed through the delay line in a printer engine control circuit, and making a decision that the relative shift of delay time from a horizontal sync signal to output of a print clock is minimal.</p> |
