C. Retraction sequence
1. Drive from the Transport motor (M1) is transmitted to the drive gear.
2. Rotation of the drive gear is transmitted to the pressure cam.
3. When the Cleaning blade pressure/retraction solenoid (SD5) is energized, the half-
moon-shaped pressure cam rotates a half turn to push the lever forward.
4. When the lever is pushed forward, the cleaning blade is retracted.
5. When the cleaning blade is retracted, it results in the cleaning blade being retracted
from the transfer belt.
