The “Ink Absorber Full” / service required message on Canon TS9055 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 TS9055. Service mode instructions are shown only when a matching series procedure is known.

What You May Notice

• Service / maintenance warning on the screen or driver
• Printer refuses to print even with ink available
• Blinking lights and queued jobs fail
• Error reappears after restart
