Replace the Paper Feed Motor Assembly (12.2.4).
3. Reconnect P/J1 and reconnect AC power. Measure the voltage
between pins 1 and 5 on P/J7 on the Controller PWB. Initiate a test
print. The voltage pulses from 5.0 VDC to approximately 0.0 VDC when
the printer initiates a paper feed signal.
Y:
Go to step 4.
N:
The problem appears to be in the printer.
4. Initiate a test print and measure the voltages listed in Table 2 during a paper feed cycle. The
voltages are correct.
Y:
Go to step 5.
