The “Ink Absorber Full” / service required message on Canon G3910 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 G3910. Service mode instructions are shown only when a matching series procedure is known.

If your Canon G3910 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.
