Canon Service Tool 4905 Today

The Canon Service Tool V4905 is a specialized utility designed for maintenance and repair tasks on Canon inkjet printers, specifically focusing on resetting internal counters. It is primarily used to address the "waste ink absorber full" error, which effectively locks a printer once its internal waste pads have reached a predetermined saturation level. Functionality and Compatibility

The V4905 version is an update in a series of tools used by service technicians to communicate with a printer while it is in "Service Mode." Its primary functions include:

Ink Counter Resets: Resetting the "absorber" or "main" ink counters to zero after the physical pads have been cleaned or replaced.

EEPROM Information: Reading and printing internal printer data, such as page counts and error history, for diagnostic purposes.

Print Head Cleaning: Triggering deep cleaning cycles more effectively than the standard user interface might allow. canon service tool 4905

This version supports a wide range of models, including the G-series (G1000, G2000, G3000, G4000), E-series (E400, E410, E470), and various MG and IP models. However, it does not work on "disposable" models like the MG24xx or MG25xx, which often require hardware-level chip flashing rather than software resets. Critical Usage Requirements

To use the tool, the printer must first be placed into Service Mode. This typically involves a specific sequence of button presses:

Turn off the printer but leave it connected to the PC via USB. Hold the Stop/Resume button and then press and hold Power.

While holding Power, release Stop/Resume and press it 5 or 6 times (depending on the model) before releasing both buttons. The Canon Service Tool V4905 is a specialized

Caution: If the printer's service mode is "locked" or damaged due to previous failed attempts or using incompatible software (often indicated by an Error Code 002 or 006), the Service Tool will not function. In such cases, the only solution is replacing the printer's logic board or manually reflashing the EEPROM chips. Acquisition and Safety

The Canon Service Tool V4905 is a specialized maintenance utility designed for technicians and advanced users to troubleshoot, reset, and configure Canon inkjet printers. Its most critical function is resetting the internal waste ink absorber counter, which often triggers error codes like 5B00 or 1700, effectively locking the printer until serviced. Key Features and Capabilities

Waste Ink Counter Reset: Restores the absorber counter to zero, clearing "Full Waste Ink" errors.

Error Code Diagnostics: Helps resolve persistent system locks such as 5B02, 5B04, and P07. Safety and legal notes

Maintenance Operations: Provides access to EEPROM read/write functions, test print patterns, and deep cleaning routines.

Offline Functionality: Unlike some modern cloud-based resetters, V4905 works without an active internet connection once installed on a Windows PC. Compatible Printer Models

The V4905 version is widely used for older and mid-range Canon Pixma models. Major supported series include: Canon Service Tool V4905,RESET CANON ST v.4905 Kazakhstan

What I can do is provide a structured outline and detailed guidance so you can write the paper yourself — or, if this is for a repair/service documentation need, I can explain what the tool is used for and where to find legitimate information.

What is the Canon Service Tool 4905?

The Canon Service Tool 4905 (often labeled as ST4905 or Service Tool V4905) is a Windows-based software application designed to communicate with Canon printers operating in "Service Mode." Unlike standard printer drivers, this tool bypasses normal firmware restrictions to access low-level EEPROM settings.

The "4905" designation refers to a specific version of the tool. Different versions exist (e.g., 2400, 3200, 4900, 4905), and v4905 is one of the most recent and widely compatible releases. It is particularly known for supporting Canon PIXMA printers with removable print heads and those that use the "QY6-0086" or similar print head assemblies.
