1.2 DRUM UNIT
An organic photoconductor drum [A] is used on this model.
A drum unit [B] is used to hold the drum to prevent stress on the drum. The
drum unit consists of an OPC drum, ID sensor [C] and pick-off pawls [D].
When the drum is replaced, and/or the pick-off pawls and/or the ID sensor
are cleaned, the drum unit must be removed from the copier as a unit.
The drum is driven by the main motor [H] through the main motor gear [E], a
relay gear and the drum drive gear [F]. The pick-off pawls [D] are always in
contact with the drum surface. The ID sensor is electrically connected to the
ID sensor connector [G].
