The Canon Service Tool 4905 (ST4905) is a specialized diagnostic software used primarily to manage and reset Canon inkjet printers. It is most commonly sought after to resolve critical maintenance errors, such as the "Ink Absorber Full" message (Support Code 5B00 or P07), which typically halts all printing operations. Key Functions of Service Tool 4905

This utility provides several professional-level maintenance options that are not available in standard printer drivers:

Waste Ink Counter Reset: Clears the internal "absorber full" counter so the printer can resume operation.

Print Head Cleaning: Initiates deep cleaning cycles to unclog nozzles and improve print quality.

EEPROM Operations: Allows users to read and save the printer's internal memory settings or print a detailed status report (EEPROM Information).

Firmware and Regional Settings: Can sometimes be used to check or modify regional configuration and firmware versions. Compatibility List

Service Tool 4905 is designed for Canon models released up to approximately July 2016. Supported series include: G Series: G1000, G2000, G3000, G1100, G2100, G3100.
