Y N
Check the circuit between PF/JF58
HCF PWB for an open or a short circuit, or a loose or damaged connector. The
are OK.
Y N
Repair as required.
Check that the resistance through Tray 6 Lift/Feed Motor is approx. 0.8 ohms at the mea-
surement points below.
• PF/JF58-3 to pins 1/2
• PF/JF58-4 to pins 5/6
The resistances are OK+
Y N
Replace the Tray 6 Lift/Feed Motor
There is +24VDC from PF/JF pins 3 and 4, to GND.
Y N
Go to IOT wirenets and troubleshoot the +24VDC circuit.
Replace the Tray 6 Lift/Feed Motor
PWB (PL 10.8).
Check the installation of the Tray 6 Stack Height Sensor
actuator. The Stack Height Sensor is installed correctly and the actuator works.
