When Canon MP648 triggers an ink absorber full condition, the printer may block printing as a protective measure. The solution is typically a waste ink counter reset.

Ink absorber pads store waste ink during normal operation. Canon firmware tracks this using a software counter and may stop printing when it reaches the limit.

This page is prepared for Canon MP648. 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 MP648 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.

Reset tools and instructions

Use a reliable USB connection and follow the steps in order.

Common Fixes

• Close other Canon printer utilities while resetting.
• Repeat the service mode steps carefully (timing matters).
• Try a different USB cable/port if using PC software.
• Use the correct Stop/Reset press count for your series.
• Power-cycle the printer and try again.
