Canon MP540 Ink Absorber Full Reset
The waste ink system in Canon MP540 collects ink used during cleaning cycles. Once the estimated limit is reached, service mode and a compatible counter reset may be required.
Why Canon MP540 reports an absorber error
Canon MP540 uses a stored counter as a maintenance safeguard. Reaching the threshold can produce an Ink Absorber Full, Service Required or related support-code message.
Wic Reset Connect is designed to reset the compatible counter in Canon MP540. The physical waste ink system should still be inspected and maintained when necessary.
