When Canon MB2720 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 MB2720. Service mode instructions are shown only when a matching series procedure is known.

How the Error Appears

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

Clear the Ink Absorber / Waste Ink Counter

Once the counter is cleared, Canon MB2720 should exit the locked state and printing should resume normally.

Warnings

Treat the reset as a maintenance step. If your printer has extremely high usage, consider cleaning/replacing absorber pads to avoid overflow.
