12-901 Power On H Transport Entrance Sensor
The H Transport Entrance Sensor detected a paper at power on, when all the interlock were
closed, or at initialization.
Procedure
Enter dC330 [012-103] and press Start. Actuate the H Transport Entrance Sensor (Figure 1).
The display changes.
YN
Disconnect P/J845 from Finisher Control PWB. Measure voltage at P/J845-A4. +5 VDC
is measured.
YN
Replace Finisher PWB (PL 17.13) (Figure 3).
Check the wire from P/J845-A4 to P/J854-2 on the H Transport Entrance Sensor for an
open circuit (Figure 2). If the wire is good, replace the H Transport Entrance Sensor (PL
17.4).
Check that the voltage at the customer outlet is in specification and does not drop during
machine start.
