When Canon MP240 triggers an ink absorber full condition, the printer may block printing as a protective measure. The solution is typically a waste ink counter reset.

During head cleaning, surplus ink is routed to internal absorber pads. Canon MP240 monitors this via a counter and can lock printing at a threshold.

This page is prepared for Canon MP240. Service mode instructions are shown only when a matching series procedure is known.

How the Error Appears

• 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

Finalize the Reset and Restore Printing

Once the counter is cleared, Canon MP240 should exit the locked state and printing should resume normally.

Warnings

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