Canon MG4120 Ink Absorber Full Reset

If your Canon MG4120 suddenly refuses to print and shows a maintenance or service warning, the ink absorber counter may have reached its limit.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MG4120 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MG4120. 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

How to Enter Service Mode on Canon MG4120

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.

Perform the Waste Ink Counter Reset

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.
