Chapter 5 : Wiring Diagrams
Use the following table to identify P/J connectors by their coordinate points. The points correlate
to the grid in the two P/J Locator illustrations on the following pages.
P/J Coordinate
location
Location of P/J and its purpose
2
I3 LVPS. Signal from the Thermistor. Labeled as P12 on the LVPS
board.
11 G6 MCU PWB. Low voltages from the LVPS.
12
E6 MCU PWB. Signals to/from the LD Drive and the Scanner Motor
(ROS Assembly).
13
E6 MCU PWB. Signals to/from the Paper Feeder PWB.
14
E5 MCU PWB. Signals to/from the Main Motor.
15
F5 MCU PWB. Signals from the CRU. Switching signals to the HVPS.
16
F5 MCU PWB. Signals from the Exit Sensor, Registration Sensor, and
MBF Sensor.
17
F5 MCU PWB. 24VDC signal to the Pickup Solenoid.
18
E5 MCU PWB. 24VDC to the Fan. (Pin 1 not connected)
19
G6 MCU PWB. 5VDC signal to the SOS (ROS Assembly).
20
G6 MCU PWB. NOT USED (For Diagnostic Tool Connection).
21
F6 MCU PWB. Signal from the Toner Sensor.
30
G7 MCU PWB. NOT USED (Used to connect to another controller).
31
G6 INTERCONNECT PWB. Connects to MCU PWB which allows signals
to/from the ESS PWB.
32
E6 MCU PWB. Used for test printing. Shorting pins 1 & 2 cause engine
self test (For Type D1 interface only).
50
F6 INTERCONNECT PWB. 5V signals to/from the console assembly
(control panel)
51
I4 INTERCONNECT PWB. Low voltages from the LVPS which in turn go
to the ESS PWB.
53
F-G 6 ESS PWB. All signals to/from print engine come from the Interconnect
PWB
101
I3 FUSER ASSEMBLY. 110 or 220 VAC from the LVPS to the Fuser
Heat Rod.
111
F5 HVPS. Signals to the HVPS. Connects to P/J 15 on the MCU.
112
F14 ROS ASSEMBLY. Signals to the Scanner Motor.
