When Canon MB2740 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 MB2740. 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

Clear the Ink Absorber / Waste Ink Counter

Once the counter is cleared, Canon MB2740 should exit the locked state and printing should resume normally.

Warnings

Treat the reset as a maintenance step. If your printer has extremely high usage, consider cleaning/replacing absorber pads to avoid overflow.

Reset tools and instructions

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

Troubleshooting

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