Canon MG7790 Ink Absorber Full Reset

The “Ink Absorber Full” / service required message on Canon MG7790 is common after many cleaning cycles. In most cases, a counter reset restores printing.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MG7790 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MG7790. Service mode instructions are shown only when a matching series procedure is known.

How to Enter Service Mode on Canon MG7790

To access maintenance functions, Canon MG7790 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 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.

Clear the Ink Absorber / Waste Ink Counter

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

Maintenance Reminder

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