Hi~
You can reset the maintenance count by going to the Configuration Menu.

Step 1: Turn off your X64x printer
Step 2: Hold the 2 and 6 buttons while the printer is off
Step 3: Turn on the printer but don't release the buttons yet. Keep holding those buttons for about 10 secs
Step 4: On your Operator Panel, you should see "Configuration Menu"
Step 5: Scroll down and look for "Reset Maint Count" and select it.
Step 6: Exit Config Menu and powercycle your printer (turn it off then back on)

Hope this is helpful... =)

NOTE: Resetting the maintenance kit counter should ONLY be done after replacing the maintenance kit.
To reset, you need to go to the printer's Configuration Menu by turning off the printer. Press and hold the Select (check) and the right arrow buttons simultaneously while powering on the printer. Release the buttons when Performing Self Test displays. Scroll down and select Reset Maintenance Count Value. Then just exit the Configuration Menu or simply power cycle the printer. Thanks.
