The voltages on the engine board, CN18 to pin
5 should measure approximately +5 V dc.
• If incorrect, replace the engine board.
• If correct, verify the voltage on CN18-6
measures approximately +5 V dc with fuser
cover 1 closed.
• If incorrect, replace the engine board.
• If correct, open and close fuser cover 1.
The voltage on CN18-6 should change
from approximately +5 V dc to 0 V dc.
• If the voltage does not change, replace
the paper exit sensor.
