Canon MX338 Ink Absorber Full Reset
When Canon MX338 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.
What stops Canon MX338 from printing
The lock is based on accumulated maintenance activity. Resetting Canon MX338 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 MX338. The physical waste ink system should still be inspected and maintained when necessary.
