• Check for any obstructions in the paper path.
Procedure
Enter dC330 008-155 Registration Sensor. Press Start. The display is H.
Y N

Y N
Connect the meter from P/J416B-9 on the IOT Drive PWB to machine frame. Actuate,
then deactuate, the Tray 5 Interlock Switch. The voltage at P/J416B-9 goes from less
than +1.0 VDC when the switch is actuated, to +5.0 VDC when the switch is deactu-
ated.
Y N
Go to Flag 4
good, replace the Tray 5 Switch
Replace the IOT Drive PWB
If the fault code is present and can not be cleared, replace the IOT Drive PWB
fault code is not present and is occurring intermittently, go to
