When Canon MB2040 triggers an ink absorber full condition, the printer may block printing as a protective measure. The solution is typically a waste ink counter reset.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MB2040 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MB2040. Service mode instructions are shown only when a matching series procedure is known.

What You May Notice

• ‘Ink Absorber Full’ / ‘Service Required’ message
• Support/service code (varies by series)
• Printing blocked after cleaning cycles
• Reset required to continue printing

Perform the Waste Ink Counter Reset

Once the counter is cleared, Canon MB2040 should exit the locked state and printing should resume normally.

Warnings

Resetting the counter does not physically clean the absorber pads. For heavy usage, pads may eventually need cleaning or replacement.
