(17) If missing strokes appear in the test print change the Stroke go multiplier setting to x4 . This
will increase the shaft encoder resolution by detecting a pulse on both the rising and falling
edge of the two shaft encoder input signal.
(18) If missing strokes continue to appear in the test print, the Encoder stroke resolution
(pulses/stroke) can be accurately set using the Digital gearbox multiplier and Digital gearbox
divider settings. It is recommended to set Encoder stroke resolution (pulses/stroke) value
between 20 to 40 using the lowest possible Digital gearbox multiplier value. The Encoder
stroke resolution (pulses/stroke) value can be set higher if required for printing 2D barcodes.
Note: The Save button will not be available for selection if the Encoder stroke resolution
(pulses/stroke) is set too high. The Encoder stroke resolution (pulses/stroke) range is
1 - 100.
(19) If there is noise on the shaft encoder input causing a false signal, change the Encoder
persistence (ms) value. This value sets the length of time the shaft encoder signal must be
active for before the printer recognises the signal as valid (Default value: 0.001).
Note: Set the persistence value as low as possible. If a high value is set then the accuracy of
the shaft encoder will be affected.
(20) Select the Encoder mode drop down setting and select one of the following options to
define the printers behaviour when the production line direction changes:
Single Mode
This mode should be used when a single ended shaft encoder is connected to the printer. The
printer will be unable to detect the production line direction and printing will occur in both
directions. If a quadrature shaft encoder is connected, the second input signal will be ignored.
Backlash Mode
Printing will only occur when the production line moves in the forward direction. When the
production line moves backward, printing is paused and a count of backward strokes (Current
backlash count) will begin. When forward motion is resumed, the backlash count will count down
until it reaches zero. Printing will resume at this point. This enables printing to resume at the exact
point it was paused.
Note: Printing will not occur in the forward direction if the current backlash count is positive.
If required, select Reset to reset the backlash count to zero.
