Theory of Operation
MFP Image Processor Board
Like the SFP Image Processor Board, the MFP Image Processor Board is connected
to the MCU Board, and controls the printer, including diagnostic, interface, and
image processing. The primary function of the IP Board is the same, but there are
two additional host data sources: the Scanner, and FAX. The received host data is
buffered, stored, and sent to the print engine in a rasterized format.
When installing a new IP Board in the printer, you must transfer the following parts
from the old board to the new board:
• Memory DIMM
• NVRAM
• FAX Board
Humidity /Temperature Sensor
The Humidity/Temperature Sensor, located on the printer’s left side in the frame
below the drive motors, reads the humidity and temperature within the printer.
Interlock Switch
The Interlock Switch interrupts the supply of +24 VDC power to the HVPS or Motor
upon the opening of the Front Cover.
Toner Door Switch
This switch signals the controller when the Toner Door is open.
