078-104 HCF Feed Out Sensor Fault RAP

BSD-ON: 8.7 HCF (Tray 6) Paper Transportation
The paper transported from HCF did not turn on the Tray 6 Feed Out Sensor within the speci-
fied time.
Initial Actions
• Clear any jam and switch the power off then on.
• Check for out-of-spec paper.
• Paper Path for a foreign object/burr/piece of paper
Procedure
Execute Component Control [078-101], Tray 6 Feed out Sensor. Block and unblock the Feed
Out Sensor. The display changes.
Y N
Go to BSD and check the following for an open wire, short or poor contact:
• Feed Out Sensor PF/JF67-1 to HCF PWB PF/JF01-3
• Feed Out Sensor PF/JF67-3 to HCF PWB PF/JF01-1
• Feed Out Sensor PF/JF67-2 to HCF PWB PF/JF01-2
If OK, replace the Feed Out Sensor (PL
Execute Component Control [078-093], Tray 6 Takeaway Motor. There is operation noise
from the Takeaway Motor.
Y N
Check the circuit between PF/JF57
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 Takeaway Motor is approx. 0.8 ohms (at 25
degrees C / 77 degrees F) at the measurement points below.
• PF/JF57-3 to pins 1/2
• PF/JF57-4 to pins 5/6
The resistances are OK
Y N
Replace the Tray 6 Takeaway Motor
There is +24VDC from PF/JF06 pins 9 and 10, to GND.
Y N
Go to IOT wirenets and troubleshoot the +24VDC circuit.
