Canon G4000 can lock printing when the waste ink (ink absorber) counter hits a predefined threshold. This guide explains how to reset it.

During head cleaning, surplus ink is routed to internal absorber pads. Canon G4000 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon G4000. 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 G4000

To access maintenance functions, Canon G4000 may need to be placed in service mode first.

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.

Perform the Waste Ink Counter Reset

Once the counter is cleared, Canon G4000 should exit the locked state and printing should resume normally.

Important Notes

Treat the reset as a maintenance step. If your printer has extremely high usage, consider cleaning/replacing absorber pads to avoid overflow.
