Determining Cue Distance and Cue Delay

Cue amplifier
The cue sensor and tach encoder, each mounted on the document
transport, are required for proper printing.
The information provided by these devices determines when printing
occurs.
Tach and cue installation are application specific. See the Installation
Guide for general installation guidelines.

Tach Encoder

The tach encoder generates pulses that indicate the travel distance and
speed of the transport (Figure 1.8). The tach rate must match (or be a
multiple of) the print resolution being used. (See your system software
operator's manual for details on selecting print resolution and tach rate.)

Cue Sensor

The cue sensor detects the substrate as it passes under the print array.
Two cue values, cue distance and cue delay, must be entered in the
system software for printing to occur at the desired position within the
image area. (Figure 1.9 shows an example of one type of cue sensor
used with the printers.)
