Canon MP540 can lock printing when the waste ink (ink absorber) counter hits a predefined threshold. This guide explains how to reset it.

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 MP540. Service mode instructions are shown only when a matching series procedure is known.

Common Symptoms

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

Finalize the Reset and Restore Printing

Once the counter is cleared, Canon MP540 should exit the locked state and printing should resume normally.

Maintenance Reminder

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