If your Canon G3400 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 G3400 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon G3400. 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

How to Enter Service Mode on Canon G3400

If your Canon G3400 supports service mode reset, follow the steps below before performing the counter 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 5 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.

Clear the Ink Absorber / Waste Ink Counter

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.
