While the waste ink counter reset is the most frequent reason users seek this software, v4905 includes a robust suite of diagnostic and configuration tools:

After prolonged use (usually 2–4 years), the printer's waste ink absorber—which collects excess ink—fills up. Once this happens, Canon printers display an error code such as and become non-functional until a service technician performs a reset.

If the Canon Service Tool v4905 does not work with your printer or you prefer an official solution, consider these alternatives:

If you want to troubleshoot a specific error you are currently facing with your Canon printer, please tell me: What is the number?

To prevent ink from leaking out of the chassis and damaging your furniture, Canon programs an internal counter chip on the logic board. When this counter reaches 100%, the printer locks itself down for safety. The v4905 software communicates directly with the printer's firmware via a USB connection to reset this counter back to 0%, immediately restoring full functionality to the machine.

Here is the reality check: This tool is not distributed by Canon publicly. It is considered "leaked" service software. Because of this, you will find it on third-party forums, file-sharing sites, and torrents.

However, the waste ink absorber has a finite capacity. When the printer’s internal counter exceeds a certain threshold—typically after , depending on the model—the printer locks itself down and displays an error. Common error messages include:

If you own a Canon inkjet printer, you have likely encountered the dreaded "Waste Ink Tank Full" error, usually signaled by error codes 5B00, 5B01, 1700, or 1702. This means your printer's internal waste ink absorber—a felt pad that collects excess ink during cleaning cycles—is full.

The physical felt waste ink pads inside the bottom of your Canon printer are genuinely saturated when this error triggers. If you reset the counter without addressing the physical ink, excess fluid will eventually overflow out of the printer housing, ruining your furniture, flooring, or internal electrical circuitry. What to do after resetting:

| Cause | Solution | | :--- | :--- | | Printer not in Service Mode | Repeat the Service Mode entry sequence. | | Wireless connection | Connect the printer via USB cable. Service Mode is not accessible over Wi‑Fi. | | Driver not installed properly | Download and install the full driver package from Canon’s official website. | | USB cable faulty | Try a different USB cable or a different USB port on your computer. |

The primary purpose of v4905 is to communicate directly with the printer's mainboard via a USB connection to reset these internal counters back to zero, allowing the machine to resume printing. Key Features of Version v4905
