Abstract
A process unit which can be removably mounted in a main assesmbly of a reproducing machine such as a xerographic copier. The unit comprises a housing enclosing an imaging member and, optionally, other processing means such as a development device, a cleaner, and a charge corotron. The unit also comprises an integral transfer corotron which has one end hingedly mounted on the housing enabling the corotron to be pivoted open for jam clearance. Preferably, the end of the corotron remote from the pivoted end is retained in the unit by a latch which is opened automatically to release the corotron when the unit is inserted into the main assembly. A flexure within the main assembly normally urges the corotron to its operative position when the unit is inserted in the main assembly, but the flexure may be withdrawn so that the corotron pivots open about its hinged end to permit jam clearance. When the unit is withdrawn from the main assembly the corotron is automatically latched back into the unit housing.
