5.12.12 Double printing
Check the sensor/ signal source to make sure that it is not triggering twice per
product. If the input is a relay, and you find that it is bouncing, then increase the
Debounce Time or Debounce distance to filter out the bounce.
5.12.13 Prints occur on every other product (or less)
The likely causes for this are timing issue (refer to Timing Issues, Section 3, for
further details).
The print cycle may be too long:
• The overall print cycle is longer than the product to product time. The
SmartDate 5 must complete its cycle before it can process the next print
signal.
Either reduce the throughput of the host machine or increase the cycle time on the
SmartDate 5. On an Intermittent printer this can be done by increasing the print
speed, or possibly the return speed, depending on the particular application. On a
Continuous printer this can be done by increasing the return speed only. Also
check the Debounce and Delay Time.
• Registration setting is too long (Continuous only)
• This can increase the Cycle time to be greater than the product to product
time, thus only printing every other product.
5.12.14 Overlapping prints
When using DRS mode to print larger images at high substrate speeds, it is
possible for the gap between prints on the ribbon to overlap. If this occurs the
Ribbon Advance setting should be increased to allow bigger gaps between the
prints on the ribbon.
5.12.15 Cropped Prints
With Combined machines if the printer is changed from an Intermittent to a
Continuous printer it is necessary to re-power the printer. If this is not done and an
image length longer than 75 mm is selected, the image will be cropped to 75 mm.
