The OPC drum [A] is 80 millimeters in diameter and 970 millimeters long. It
turns constantly when the main motor [B] is on.
When the main motor turns on, drive is transmitted to the drum as follows:
main motor drive gear [C]
drum drive belt [F]
When the drum knob [I] is tightened, the right flange [J] presses firmly against
the drum so that the drum is held tightly between the flanges. The drum and
flanges turn together when the main motor is on.
