Abstract

Disclosed is the use of firmware for counting the number of times a print cartridge contained in a Thermal Ink Jet (TIJ) printer fires its jets during a cleaning cycle at the maintenance station. A counting routine signals the printer when it is time for the cleaning cycle. The printer pauses until the operator removes the print cartridge and replaces it with a cleaning apparatus. Then the printer goes through the cleaning cycle after which; the firmware resets the counter. After the cleaning cycle, the printer resumes normal operation once the printing cartridge is replaced.
