Canon MX390 Ink Absorber Full Reset
The waste ink system in Canon MX390 collects ink used during cleaning cycles. Once the estimated limit is reached, service mode and a compatible counter reset may be required.
What the Canon MX390 service message means
The absorber pads collect ink generated during print-head cleaning. Canon MX390 tracks those maintenance cycles in memory rather than measuring the pads directly.
Wic Reset Connect is designed to reset the compatible counter in Canon MX390. The physical waste ink system should still be inspected and maintained when necessary.
