The HCF Stack Height Sensor failed to change state within the specified time after the HCF
Tray started to lift.
NOTE: Prior to switching off the machine, ensure all pendi
ng jobs are saved.
Initial Actions
• Check for obstructions in the paper path.
• Ensure connector P/J8
41 on the HCF Control PWB is seated properly.
• Refer to BSD 7.11 and 7.12 in the following procedure.
Procedure
Enter dC330, 007-186 HCF Stack Height Sensor and press Start. Pull the HCF Tray out.
The display changed from L to H.
YN
Check for +5VDC between pins 1 and 3 of P
/J
841 on the HCF Control PWB. +5VDC is
measured between pins 1 and 3 of P/J841.
YN
Check for +5VDC between pins 3 and 4 of J2
HCF Cont
rol PWB. +5VDC is mea-
sured between pins 3 and 4 of J2.
YN
Check for +5VDC between pins 20 and 9 of P/J44 Distribution PWB. +5VDC is
measu
red b
etween pins 20 and 9 ofP/J44.
YN
Go to Wirenet +5 VDC-1 Figure 7.
Go to F
lag 3 on BS
D 8.13. Check the connector and wiring for an open circuit.

Ensure that the Elevator Motor energizes. The Elevator Motor energizes and then deener-
gizes within 30 seconds.
YN
Check for +24VDC between pins 2 and 1 of P
/J
845 HCF Control PWB. +24VDC is mea-
sured between pins 1 and 2 of P/J845 on
the HCF Control PWB (This measurement
must be taken within 30 seconds after closing the tray.)
YN
Check for +24VDC between pins 1 and 2 of J2HCF
Control PW
B. +24VDC is mea-
