The voltage is 5.0 +/- 0.25 VDC.
Y:
Go to step 3.
N:
The printer is not supplying 5.0 VDC to the High Capacity
Feeder. Troubleshoot the printer.
3. With the paper tray in the feed position, measure the voltage from P/J7
pin 3 to pin 5. The voltage is correct for the setting of the Paper Length
Guide (Table 1).
Y:
Go to step 4.
N:
Perform procedure (12.6.4) Paper Size Switches.
4. Measure the voltage from P/J7 pin 2 to pin 5. The voltage is 5.0 +/- 0.3 VDC with
the feeder in a no paper condition and 0.0 VDC with paper in the feed position.
Y:
Go to step 5.
N:
Perform procedure (12.6.6) Tray Empty Sensor.
5. Measure the voltage from P/J7 pin 1 to pin 5. Initiate a test print. The voltage
pulses from 5.0 +/- 0.3 VDC to 0.0 VDC during a paper feed cycle.
Y:
Go to step 6.
N:
The problem appears to be in the printer. Troubleshoot the printer.
6. All signals between the printer and the feeder are correct. Return to Initial Actions and continue.
