Drum support roller
There are three small rollers with gum rings near where the drum is to be removed, to
prevent the drum surface from contacting metal parts in the vicinity.
To remove the rollers on the lower right and left, remove the screws (1 each) securing
each bracket.
The roller on the upper right is attached to the bracket of the drum surface potential
sensor. To replace the rubber ring of this roller, remove the gum ring from the roller.
