The control system of an electrophotographic copier includes jam recovery arrangements. The copier employs an automatic document feed system for feeding original documents in turn from a stack to an exposure station. When a copy sheet jam occurs, the original document at the exposure station is registered in a register stack (232) of a data store (230). The number of copies lost by jams are recorded in a copy count register stack (234) in the data store. At the end of the copying run from the original document stack, these can be reloaded and a further run processed using the data from the store to produce those copies lost during the first run. In order to assist re-collation of the replacement copies into the set, blank sheets may be fed to the copy collection device in place of the copies lost by jamming. |
