MG3640 Ink Absorber Full Reset – Step-by-Step Guide

Canon MG3640 Ink Absorber Full Reset

The “Ink Absorber Full” / service required message on Canon MG3640 is common after many cleaning cycles. In most cases, a counter reset restores printing.

Ink absorber pads store waste ink during normal operation. Canon firmware tracks this using a software counter and may stop printing when it reaches the limit.

This page is prepared for Canon MG3640. 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)

Reset required to continue printing

How to Enter Service Mode on Canon MG3640

Some Canon series require entering service mode before the ink absorber counter can be reset.

Turn the printer OFF.
Press and hold Stop/Reset.
While holding Stop/Reset, press and hold Power.
Release Stop/Reset (keep holding Power).
Press Stop/Reset 6 times.
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.

Important Notes

If absorber pads are truly saturated, ignoring maintenance can lead to ink leakage inside the printer. The counter reset only removes the software lock.

Use the correct Stop/Reset press count for your series.
Close other Canon printer utilities while resetting.
Repeat the service mode steps carefully (timing matters).
