Shaft Encoder (Optional)
The shaft encoder is used to match the printing speed to the speed of the
target material as it passes the printhead. The encoder is connected to the
controller’s encoder input.
Measurement of the speed by means of shaft encoder
For optimal printing, precise speed measurement is needed. Since the
speed of the product may fluctuate slightly (for example, because of
unevenness in the conveyor belt or starting and stopping of production),
the use of an external shaft encoder is recommended.
The shaft encoder must ideally be mounted to run on the conveyor, close
to the printer, in order to accurately measure the product speed. Any
discrepancy between measured and actual speed can result in poor print
quality.
The use of a quadrature mode encoder is strongly recommended.
Installation of the External Shaft Encoder
For smooth or hard belt surfaces
(suitable for standard shaft encoders)
