: Resets the internal counter for the waste ink pad, allowing the printer to resume operation after it thinks the pads are full. Print Head Calibration
Works with many G-series (G1000, G2000, G3000) and PIXMA MG/IP/MX models.
: Initiates deep cleaning cycles for the print head beyond what is available in the standard user driver menu.
: Allows for resetting the printer to factory default settings.
