2.5 Print Signal Issues
2.5.1 Debounce Time
This is an Intermittent printer setting.
This is the time that the PRINT GO signal must be present before it is actioned.
This avoids double triggering of the print signal if the signal is particularly noisy
(e.g ringing on a relay contact)
If the signal used is arriving as a double pulse, set the Debounce time just high
enough to stop the printer double printing.
The print signal is sampled every 5 milliseconds, so if the Debounce Time is set to
10 milliseconds, the Print Signal must be at least 15 milliseconds.
2.5.2 Debounce Distance
This is a Continuous printer setting.
This is the distance that the substrate must travel after receiving a PRINT GO
signal. This is similar to the debounce time for Intermittent printers in that it
ensures that the print signal is valid and not double triggering.
Note: The Debounce Time and Debounce distance increase the overall cycle
time of the printer and should be kept as low as possible. On Continuous
printers, it is advisable, where possible, to set the debounce distance to
zero. Otherwise a time delay is introduced into the cycle which may
produce print drift.
2.5.3 Print Delay
This is an Intermittent printer setting.
With SmartDate 5 Intermittent printers, this sets a delay between a valid PRINT
GO signal and when the Printhead is moved out into position.
If the PRINT GO signal is received before the substrate is stationary, this allows
time for the substrate to settle before printing commences.
Set the print delay setting as low as possible as it increases the overall cycle time
of the printer.
