Canon Service Tool 4905 -

Canon Service Tool v4905 is a specialized maintenance utility software used for resetting and servicing Canon inkjet printers. It is the successor to earlier versions (such as v3600 and v4700) and is primarily required for newer Canon printer models. The software allows technicians to perform "Waste Ink Counter" resets, clear error codes, and perform system diagnostics that are not accessible through standard printer drivers.

Canon printers count every drop of ink that is purged during cleaning cycles. This waste ink is absorbed by foam pads inside the printer. The printer has a predetermined counter (usually around 7,000 to 15,000 purge cycles). Once reached, the printer locks up with an error message like:

In reality, the pads may still have capacity, but Canon’s firmware is programmed to force a service call. A repair technician would either replace the pads (labor-intensive) or simply run the Canon Service Tool 4905 to reset the counter. The tool effectively gives you that same power at home.
