Canon MG7770 Ink Absorber Full Reset

The “Ink Absorber Full” / service required message on Canon MG7770 is common after many cleaning cycles. In most cases, a counter reset restores printing.

Inside Canon printers, absorber pads collect excess ink from cleaning and maintenance cycles. The printer uses an internal counter to estimate pad saturation.

This page is prepared for Canon MG7770. 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 MG7770

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

After service mode is enabled (if required), the waste ink counter can be reset using a supported reset procedure/software.

Warnings

Resetting the counter does not physically clean the absorber pads. For heavy usage, pads may eventually need cleaning or replacement.

Reset tools and instructions

Use a reliable USB connection and follow the steps in order.

If It Doesn’t Work

• 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.
• Close other Canon printer utilities while resetting.
• Repeat the service mode steps carefully (timing matters).
