If you own a Canon MAXIFY MB2140, you rely on it for high-volume printing, crisp documents, and efficient all-in-one functionality. But what happens when, in the middle of a critical print job, your screen flashes a cryptic message like: “Service error 5B00” or “Ink absorber full” ?
For many users, this appears to be a death sentence for the printer. In 2021, Canon continued its policy of locking printers after a certain number of cleaning cycles, forcing users to either pay expensive repair fees or buy a new printer. However, there is a powerful solution: the Canon MB2140 Service Tool 2021.
This article provides a deep dive into what this tool is, how it works, the risks involved, and a step-by-step guide to using it to restore your MB2140 to full working order.
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.
The Canon Service Tool (also known as a resetter or adjustment program) is an unofficial software application designed to interface with your printer’s service mode. This tool communicates directly with the printer’s EEPROM (memory chip) to reset specific counters.

Important Distinction: This is not a driver or a firmware update. It is a maintenance utility. The "2021" designation typically indicates a version of the tool (e.g., v4720, v3400) that was confirmed to work with the MB2140’s firmware up to the year 2021.
Canon technicians use proprietary software known as OSST (Official Service Support Tool). This software is secured by a hardware dongle (USB key) and requires official Canon credentials to operate. It is the only guaranteed method to reset the MB2140 absorber counter safely.
Yes, if: You are technically comfortable, have already cleaned the physical waste pads, and want to extend the life of a reliable printer.
No, if: Your printer has already leaked ink inside, or you cannot accept the risk of bricking the device.
For the vast majority of Canon MB2140 owners who encountered the dreaded 5B00 error in 2021, this service tool was a lifesaver. It bypassed planned obsolescence and returned full functionality. As of today, the 2021 version remains the most stable release for this specific model. Always keep a copy of the tool and a guide to entering service mode handy – because if you print heavily, you will need it again.
