Canon MX439 Ink Absorber Full Reset
When Canon MX439 reports that the ink absorber is full, turning it off and on will not normally remove the lock. The printer must be prepared correctly and its counter reset.
Why Canon MX439 reports an absorber error
The lock is based on accumulated maintenance activity. Resetting Canon MX439 changes the counter value but does not remove ink already held in the absorber material.
Wic Reset Connect is designed to reset the compatible counter in Canon MX439. The physical waste ink system should still be inspected and maintained when necessary.
