Canon MB5090 Ink Absorber Full Reset
If Canon MB5090 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.
What the Canon MB5090 service message means
The absorber pads collect ink generated during print-head cleaning. Canon MB5090 tracks those maintenance cycles in memory rather than measuring the pads directly.
Wic Reset Connect is designed to reset the compatible counter in Canon MB5090. The physical waste ink system should still be inspected and maintained when necessary.
