Abstract:
A reproduction machine (10) for making copies from original documents includes a paper path through which sheets of paper are passed by transport devices during reproduction operations to various stations (A - E) in the machine for operation thereon. A diagnostic system is included for examining the operation of the transport devices moving the paper sheets through the paper path, comprising: paper path sensors (S1 - S5) located along the paper path for sensing the passage of paper sheets as they are moved therethrough; a device clock (CK) for generating information regarding the times of sheet passage past the sensors; an addressable memory (114) for storing data representative of machine operating time and corresponding to paper sheet passage past the sensors for a number of paper sheet passages; a non-volatile memory (120) for storing data corresponding to the passage of paper sheets past the paper path sensors on receipt thereof from the addressable memory, and a control (24) and display (26) for accessing and reviewing the memories containing time information representative of paper sheet passages.
