Principles of Operation
Figure 1 LEDs on the HVF control PWB
Figure 2 shows the LEDs on the BM PWB. These are:
• LED 1 - red, steady. The LED indicates a fault or other abnormal status.
• LED 2 - yellow, flashing at about 1Hz. The LED indicates that the software is operating in
normal mode. In other modes, e.g., software downloading, the flashing rate is higher.
• LED 3 - orange, steady. The LED indicates either:
– that the tri-folder front door and top cover interlocks are closed, and +24V is avail-
able to the BM module or, if the tri-folder in not installed;
– that the interlock cheater is present in PJ553 on the BM control PWB the logic
cheater is present in PL563 on the BM control PWB.
• LED 4 - orange, steady. The LED indicates that the +24V supply is within voltage and cur-
rent limits, and that the power limiting circuit has not been active for over a set time limit.
• LED 5 - blue, steady. The LED indicates that the +5V supply is present in the BM module.

Paper Paths
This covers the motors, sensors, solenoids, etc., along the paper paths.
• Entry Sensor, Q12-077 - This is a reflective sensor at the HVF input transport, receiving
paper from the IME. Refer to
Figure 3 .
• Transport motor 1, MOT12-223 - This is a stepper motor, located at the rear of the HVF,
and driving a toothed belt. This provides the drive to the input path from the IME. It also
drives the vertical paper path from the inserter and takes the paper through to the hole
punch. Refer to
Figure 3 .
