Canon MB2140 can lock printing when the waste ink (ink absorber) counter hits a predefined threshold. This guide explains how to reset it.

Inside Canon printers, absorber pads collect excess ink from cleaning and maintenance cycles. The printer uses an internal counter to estimate pad saturation.

This page is prepared for Canon MB2140. 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

Perform the Waste Ink Counter Reset

Once the counter is cleared, Canon MB2140 should exit the locked state and printing should resume normally.

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.
