The Control Logic has detected the Platen Angle Sensor is not in the correct state for the Job
Programed.
Initial Actions
• Refer to BSD 6.2 and BSD 6.7 in the following procedure.
• Check the Document Handler for dirt or debris.
• Check that the Document Handler Cover opens and closes without binding.

+5VDC is measured between
P/J515 -6 and P/J515 -2 on the Pre IPS PWB.
Y N
Go to Flag 2 on BSD 6.2 and check the wires for an open or short circuit. If
the wires are OK, replace the Pre IPS PWB. ( PL 3.5 ).
Go to Flag 2 on BSD 6.2 and check the wires for an open or short circuit. If the
wires are OK, replace the Platen Angle Sensor ( PL 3.2 ).
+5VDC is measured between P/J515 -4 to GND on the Pre IPS PWB.
Y N
Go to Flag 3 on BSD 6.2 and check the wire for an open or short. If the wire is
OK, replace the Pre IPS PWB ( PL 3.5 ).
Clean and check the Platen Angle Sensor for damage. If the problem continues,
replace the Platen Angle Sensor (
PL 3.2 ).
Block and unblock the Platen Angle Sensor. The Display changes.
