2.2 Main Control PCB
The main control PCB controls the operations of all machine functions.
Jumper JP2 on the main control PCB is used for battery back up of the SDRAM. Removing JP2 will
initialize the SDRAM. If the power is turned off, the battery will provide up to 72 hours (8MB) of back up
when fully charged.
Jumper JP1 on the main control PCB is used for battery back up of the SRAM. All user programmed data
and internal memory switch settings are held in SRAM. Removing JP1 will initialize the SRAM.
If the power is turned off, the battery will provide up to five years of back up when fully charged.
NOTE: JP1, JP2 should remain in the "ON" position at all times.

NOTE: The SDRAM back-up battery is connected to the PCB MAIN. When the PCB MAIN is replaced,
the connection will be lost. Therefore, please reenter the date and time, after you have replaced
the PCB MAIN. (Press MENU, 2, 1, 0, 9, and enter month, then day, year, hour and minute in 24-
hour format.)
NOTE: Turning parameters for Color(R,G,B) and Gray mode are stored in the EEPROM(IC42). When the
PCB MAIN is replaced, the EEPROM on malfunction PCB should be replaced to the new PCB.

Connects the telephone line to the fax.
S relay
Used to connect the telephone line at seizure state.
OH & Tone detector
Detects the On-hook condition of the second telephone unit.
H relay
Disconnects the Tel1 and Tel2 line from PSTN.
24V generator
Supplies 24 volts to the relays for OH detection of optional handset or external telephone line.

2.4 Power Supply Unit (PSU)
The power supply unit receives the input line voltage and currents it to output voltages of +5 VDC, +24
VDC, +12 VDC, and -12 VDC.
The heater circuit controls output voltage to the fuser heater according to instructions received from the
heater control circuit.
If an over-current is sensed in the secondary circuit, power is interrupted.
Power supply unit block diagram
The power supply unit has two output connectors.
The following table shows the connector outputs:

2.6 Document Scanning Sequence
2.6.1 ADF Detection
When a document is placed into the document feeder, Document Sensor 1 (DS1) is activated and you
will hear the short beep.
The document will be transferred when the start key is pressed.
Document separation is the process that allows a multi-page document to go through the scanner one
page at a time. The bottom document is separated from the remaining documents by the friction of the
separator pad.
Following the document separation, the feed roller causes the document to advance. As it advances, the
leading edge of the document activates the Document Sensor 2 (DS2) sensor. Once DS2 is activated,
the feed roller continues to rotate until the document reaches the scan position. The machine uses the
distance from DS2 to the scan position and the diameter of the feed roller to determine the number of
rotations necessary to feed the document to the scan position.
When the document reaches the scan position, the light from the scanner lamp strikes the face of the
document and is reflected into the lens through mirrors A, B, and C. In case the light intensity along the
length of the scanner lamp is not uniform, shading compensation is provided to ensure even illumination.
As the reflected image passes through the lens, it is focused onto the charged coupled device (CCD).
The CCD then converts the dark and light areas of the image into electrical impulses, or image data.
When DS2 detects the trailing edge of the document, the image signal output is turned off. The scanner
continues to remain active for a few more seconds in case there is another document to follow.
The scanned document is discharged through the document exit by the exit roller.
