after using refilled cartridge in canon printer E510 showing error E16. how can I solve this problem
Resetting the waste ink absorber on a Canon printer can resolve some error codes that appear when turning it on.
Make sure the printer is turned off.
Press and hold the Resume button (triangle inside a circle).
Whilst it is held down, hold down the Power button. The green led light should come on.
Keep the Power button held down. Release the Resume button and then press it twice. The light should go amber, then green again.
Release the Power button.
Press the Resume button four times and then press the Power button straight after to confirm the selected action (Reset Counter Absorber).
Turn off the printer and then turn it on again
