Abstract
A card processing system includes a drop-on-demand card printing system that has at least one drop-on-demand print head with a nozzle plate. An automated cleaning mechanism is provided in the drop-on-demand card printing system that is configured to clean the nozzle plate without the cleaning mechanism physically contacting the nozzle plate. Since the nozzle plate is not physically contacted by the cleaning mechanism, damage to the nozzle plate during cleaning is avoided thereby avoiding degrading the resulting print quality of the print head.
