Note
A replacement sensor assembly must be precisely reinstalled on the
drum shaft in the position of the original sensor assembly. This
ensures that the stripper fingers contact the drum in the same location
as before; otherwise, serious print artifacts will result.

Turn off the printer and remove the power cord.
2. Remove the top and left -side covers as explained in the earlier topic,
"Cabinet panels and covers" on page 8-4.
3. Unloop the drum temperature sensor's wiring harness from its
retainer on the side of the drum position sensor assembly.
4.
Disconnect the home-position sensor wiring harness from I/O board 1
leading to the drum position assembly. Disconnect the drum position
encoder sensor at the drum position assembly.
