Canon G3915 Ink Absorber Full Reset

The “Ink Absorber Full” / service required message on Canon G3915 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 G3915 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon G3915. Service mode instructions are shown only when a matching series procedure is known.

Typical Signs

• ‘Ink Absorber Full’ / ‘Service Required’ message

• Printing blocked after cleaning cycles
