If you have exceeded the maximum number of inserted cards between two cleaning cycles, the print head warranty is voided. You can determine this by printing a Technical Test card.
Determining if you have met the required cleaning cycles:
Print a Technical Test Card
If the second number in the Cleaning Cycles H is greater than 500 for a Tattoo2, 1200 for a Pebble4 and Dualys 3, – or 1600 for a Kiosk and Quantum 2, or 1200 for a Zenius and Primacy, you have not met the required cleaning cycles and your print head warranty is voided.
Cleaning Cycles H:
Number of cleaning cycles / Maximum number of inserted cards between 2 cleaning cycles
With the last installed print head
Cleaning Cycles G:
Number of cleaning cycles / Maximum number of inserted cards between 2 cleaning cycles Since day 1
