Canon PIXMA MP780 Waste Ink Full

1) With the printer power turned off, while pressing the Resume/Cancel button,
press and hold the Power button. (DO NOT release the buttons. The Power LED
lights in green to indicate that a function is selectable.)
2) While holding the Power button, release the Resume/Cancel button.
(DO NOT release the Power button.)
3) While holding the Power button, press the Resume/Cancel button 2 times,
and then release both the Power and Resume/Cancel buttons. (Each time the
Resume/Cancel button is pressed, the Alarm and Power LEDs light
alternately, Alarm in orange and Power in green, starting with Alarm LED.)
4) When the Power LED lights in green, press the Resume/Cancel button the specified
number of time(s) according to the function listed in the table below. (Each time
the Resume/Cancel button is pressed, the Alarm and
Power LEDs light alternately, Alarm in orange and Power in green, starting with
Alarm LED.) [hth: I believe the power button has to be pressed once more after
cycling the alarm button to complete the action. The power/resume-cancel button
LEDs toggle to help you count.]
