More Information
Summary:Maintenance routines that can be used to maintain the operability of one or more DOD print heads in a card processing system. The maintenance routines can include, but are not limited to: a cover routine where a cover or cap is selectively and automatically located over the print head(s) to protect the print head(s); a shake pulse routine that energizes the nozzles of the print head(s) without causing an ejection of ink; a spit routine where the nozzles of the print head(s) are energized to eject one or more drops of ink; and a purge routine where the nozzles are not electrically energized but the pressure holding the ink in the nozzles of the print head(s) is reversed to push ink out of the nozzles.
