Status Indicator RAPs
Initial Issue
078-102 HCF to Registration Sensor Fault RAP
BSD-ON:
BSD 8.4 - Tandem Tray Module Takeaway Drive
BSD-ON:
BSD 8.5 - Registration
The paper transported from HCF did not turn on the Registration Sensor within the specified
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
[077-104], Reg. Sensor. Block and unblock the Reg. Sensor. The
display changes.
Y
N
The connection between the Registration Sensor
P/J121
and the MCU PWB P/J 415 for
open circuit, short circuit, and poor contact. If OK, replace the Registration Sensor (
PL

)
Press the Stop button. Turn ON
Component Control
[077-033] (TM Takeaway Motor).
Does the TM Takeaway Motor rotate?
Y
N
Is the voltage between the TM Takeaway Motor
P/J224
-2/5 (+) and the GND (-)
+24VDC?
Y
N
Go to +24VDC Power RAP.
Turn the power OFF, disconnect the TM Takeaway Motor connector
P/J224
.
Measure the TM Takeaway Motor wire wound resistance.

Is the resistance approx. 0.85Ohm for each? (When the temperature is 25
°
C)
Y
N
Replace the TM Takeaway Motor (
PL 11.5
)
Measure the resistance between the disconnected TM Takeaway Motor connectors
P/
J224
-1/3/4/6 and the Frame. Is the resistance infinite for all?
Y
N
Check the wires of the pins with non-infinite resistance for peeled-off coatings and
short circuits due to pinching.
Check the connection between the Tray Module PWB
P/J554
and the TM Takeaway
Motor
P/J224
for open circuit, short circuit, and poor contact. If no problems are found,
replace the following parts in sequence:
•
Tray Module PWB (
PL 11.13
)
•
MCU PWB (
PL 18.2
)
Check the following:
•
Takeaway Rolls 1 and 2 and 3 for dirt/paper particles/wear/a poor rotation
•
HCF and IOT for a poor docking
•
HCF Transport Belt for poor tension
•
HCF Transport Roll for dirt/paper particles/wear/a poor rotation
•
HCF Takeaway Rolls 1-3 for dirt/ paper particles/wear/a poor rotation
•
HCF Exit Roll for dirt/ paper particles/wear/a poor rotation
•
Drive gears for wear/breakage
•
If the results of the above checks are OK, replace Tray Module PWB (
PL 11.13
).
