Canon MB2790 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 MB2790. Service mode instructions are shown only when a matching series procedure is known.

Typical Signs

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

Reset the Ink Absorber Counter

Once the counter is cleared, Canon MB2790 should exit the locked state and printing should resume normally.

Important Notes

If absorber pads are truly saturated, ignoring maintenance can lead to ink leakage inside the printer. The counter reset only removes the software lock.
