The “Ink Absorber Full” / service required message on Canon MG6870 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 MG6870 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MG6870. Service mode instructions are shown only when a matching series procedure is known.

How to Enter Service Mode on Canon MG6870

To access maintenance functions, Canon MG6870 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.

Reset the Ink Absorber Counter

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

Maintenance Reminder

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