Engine Logic Board
The Engine Logic Board manages the printing operation according to information
obtained through communications with the I/P Board and from sensors and switches
located throughout the printer.
The Engine Logic Board performs seven main functions:
■ Communicates with the Image Processor.
■ Controls the print sequence.
■ Distributes low DC voltages to various printer components.
■ Monitors printer status.
■ Maintains a running print count.
■ Writes the NVRAM settings.
■ Controls printer options.
