If Canon MX491 displays an ink absorber full or service-required warning, the stored waste ink counter may have reached its limit. This guide covers service mode, USB preparation and the reset itself.
The waste ink counter inside Canon MX491
An absorber message concerns both software and maintenance. The counter can be reset, while heavily saturated pads may still need cleaning or replacement.
Wic Reset Connect is designed to reset the compatible counter in Canon MX491. The physical waste ink system should still be inspected and maintained when necessary.
