08-192 HCF Take Away Roll Sensor On Jam RAP
The control logic detected that paper from the HCF was late to the IOT Takeaway Sensor.
Initial Actions
• Check for obstructions in the paper path
• Check to ensure that the Feed Belt is not overtensioned
• Check for contamination on the HCF TAR Sensor lens
• Ensure that connector P/J405 on the IOT CPU PWB is seated correctly
• Refer to BSD 8.11 and 8.12 in the following procedure.
Procedure
Cheat the L/H Cover Interlock Switch. Enter dC330 008-150 Take Away Sensor and press
Start. Block the Takeaway Sensor with a sheet of paper. The display changes from H to L.
YN
The display indicates a constant H.
YN
Go to Fl
ag 1 on BS
D 8.6 and check the harness for a short circuit. If the harness is
good, replace the Takeaway Sensor (PL 2.8).
Connect the meter from P/J420-B5 on the IOT Drive PWB to machine frame. Block the
Take
away Sensor with a sheet of paper. The voltage at P/J420-B5 goes from +5 VDC
when
the sensor is unblocked, to less than +1.0 VDC when the sensor is blocked.
YN
There is +5 VDC between P/J420-B6 and P/J420-B4 on the IOT Drive PWB.
YN
Go to F
lag 2 on BSD 8.6 and check the harness for a short circuit. If the har-
ness
is good, replace the IOT Drive PWB (PL 9.
2).
Go to Flag 1 and Fla
g 2 on BSD 8.6 and check the harness for an open circuit. If the
harness is OK, replace the Takeaway (D1-T/A) Sensor (PL 2.8). If the problem con-
tinues, replace the IOT Drive PWB (PL 9.2).
Replace the IOT Drive PWB (PL 9.
2).
Ent
er dC330, 007-080 HCF Feed Motor and pr
ess Start.
Check that the HCF Feed Motor energizes. The HCF Feed Motor energizes.
YN
Check for +24VDC between pins 1 and 2 of J2 on
th
e HCF Control PWB. +24VDC is
measured between pins 1 and 2 of J2 on the HCF Control PWB.
YN
Check for +24VDC between pins 13 and 17 of P/J45 on the Distribution PWB.
+24VDC is measured between pins 13 and 17 of P/J45 on the Distribution

Go to Fl
ag 2 on BSD
8.13. Check the connectors and wiring.
Go to Flag 1 on
BSD 8.11. Check the connectors and wiring.
If the connectors and wiring are OK, then replace the HCF Feed Motor (PL 15.10).
Ent
er dC330, 007-078 HCF Feed Clutch and press Sta
rt.
Check that the HCF Feed Clutch energizes. The HCF Feed Clutch energizes.
YN
Check for +24VDC at pins 1 and 3 of J-851 on the HCF Feed Clutch. 24VDC is mea-
sured at pins 1 and 3 of J-851 on the HCF Feed Clutch.
YN
Check for +24VDC between pins 11 and 10 of P/
J841 on th
e HCF Control PWB.
+24VDC is measured between pins 11 and 10 of P/J841
on the HCF Control
PWB.
YN
Replace the HCF Control PWB (P
L 15.16
).
Go to Flag 2 on BSD 8.12. Check the connectors and wiring. re
pair or replace as
required (PL 15.11).
Go to Flag 2 on BS
D 8.12. Check the connectors and wiring.
If the connectors and wiring are OK, then replace the HCF Feed Clutch (PL 15.13
).
Check /replace the following components until the problem is resolved. Replace any compo-
nents that are worn, broken, binding, loose or slipping.
