ABSTRACT:
Random access memory (RAM) clock switching circuitry for a laser printer having a RAM for storage of microprocessor information plus storage of font information with separate clock generators is provided for use in accessing the two types of information. The switching circuitry has a switch portion for alternately connecting the clock generators to a lockout circuit portion. A lockout request signal from the laser printer microprocessor determines when clock pulses presented to the lockout circuit can be applied to the RAM.
