  Single Channel Encoders
Single channel encoders can be used with SmartDate 5 continuous printers, but will not 
be as efficient as quadrature encoders.
The substrate movement is recorded in one direction only, any drift backwards is not 
accounted for.
The setting for this type of encoder is External - Pulse train. This covers single channel 
encoders and bagging machines that output a single channel movement signal.
  Fixed Speed settings
This setting can be used if the substrate runs at a constant known speed. The set-
ting for this method of running is Internal, and the substrate speed must be manually 
entered.
  With images that are longer than 50mm the encoder must be re calibrated
