Theory of Operation
Electrically Erasable Programmable Read-Only Memory (EEPROM) Board
The EEPROM Board stores the printer unique information.
Image Processor Board
The Image Processor (I/P) Board (CONT AIO) is connected to the MCU Board,
which controls the printer, including diagnostic, interface, and image processing.
The primary function of the I/P Board is to receive host data through one of the
available ports (USB, or Ethernet, the Scannner, or FAX). The received host data is
buffered, stored, and sent to the print engine in a rasterized format.
When installing a new I/P Board in the printer, you must transfer the following
parts from the old board to the new board:
•
Memory DIMM
•
FAX Board
Humidity /Temperature Sensor
The Humidity/Temperature Sensor reads the humidity and temperature within the
printer.
