Canon IB4040 Ink Absorber Full Reset

When Canon IB4040 triggers an ink absorber full condition, the printer may block printing as a protective measure. The solution is typically a waste ink counter reset.

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 IB4040. Service mode instructions are shown only when a matching series procedure is known.

Typical Signs

• 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

After service mode is enabled (if required), the waste ink counter can be reset using a supported reset procedure/software.

Before You Continue

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

Reset tools and instructions

For best results, avoid rushing button presses—consistent timing matters.

Common Fixes

• Try a different USB cable/port if using PC software.
• Power-cycle the printer and try again.
• Repeat the service mode steps carefully (timing matters).
• Use the correct Stop/Reset press count for your series.
• Close other Canon printer utilities while resetting.
