The “Ink Absorber Full” / service required message on Canon TS6391 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 TS6391 monitors this via a counter and can lock printing at a threshold.
