Canon Mb2140 Service Tool 2021

The Canon MAXIFY MB2140 is a business-oriented inkjet printer. Like most modern inkjet printers, it contains an internal "absorber counter" that estimates the saturation of the waste ink pad. When this counter reaches a predefined limit, the printer halts operation and displays an error (typically "Support Code 5B00" or a warning regarding the waste ink absorber).

But that hurdle is why this tool gets 1-star reviews from frustrated beginners and 5-stars from veterans. The Canon MAXIFY MB2140 is a business-oriented inkjet

This is a gray area. Canon does not officially distribute the service tool to end users. It is intended for authorized service centers. However, the tool has been leaked online by technicians and enthusiasts.

Safety considerations for 2021 users:

Legal note: Resetting the counter does not physically replace the waste ink pads. If the pads are truly saturated, ink may leak inside the printer, causing damage or electrical shorts. Use this tool at your own risk.

Using the Canon MB2140 Service Tool 2021 performs a logical reset – it changes a number in the printer’s memory. However, the physical waste ink pads inside the printer remain full. Legal note: Resetting the counter does not physically
