Canon MG6821 Ink Absorber Full Reset

If your Canon MG6821 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

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 MG6821. 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

How to Enter Service Mode on Canon MG6821

Some Canon series require entering service mode before the ink absorber counter can be reset.

1. Turn the printer OFF.
2. Press and hold Stop/Reset.
3. While holding Stop/Reset, press and hold Power.
4. Release Stop/Reset (keep holding Power).
5. Press Stop/Reset 6 times.
6. Release Power — the printer should enter service mode.

If it doesn’t work, repeat the sequence carefully. The press count depends on the series.

Reset the Ink Absorber Counter

Completing the reset clears the internal ink absorber counter stored in printer memory and restores normal operation.

Before You Continue

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

If your model does not show a service mode section, it means no matching procedure was found for its series.

If It Doesn’t Work

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