Abstract
A copy production machine is capable of having copies from plural independent copy runs in a copy sheet transport path at a given instant. Such independent runs are combined to produce duplex (double-sided) copies. Recovery from jams in such duplex operations is described. The described system also distinguishes between copy sheets having images and non-imaged copy sheets. Apparatus and procedures are described for utilizing the counts for precisely recovering from loss of copy sheets due to a jam or other stoppage condition. Control of a billing meter is also disclosed.
