Canon Service Tool 4905 -
Technical Paper: Canon Service Tool v4905
Legitimate alternatives for common issues
- "Printer error has occurred. Please contact service center." (5B00)
- "Ink absorber is full. Service required." (5B02)
Legal and Ethical Considerations
- Click the EEPROM button. A text window will appear. Scroll down – you should see
Dd=000.0orMain=0. This confirms the counter is zeroed.
- Resetting Waste Ink Pads: After the printer reaches its internal waste ink counter limit (causing a "Service Mode" or "5B00" error), v4905 can reset the counter. Note: This does not physically replace the ink absorber pads.
- Clearing EEPROM Data: Resetting the printer’s permanent memory to factory defaults, which can resolve certain logic board issues.
- Changing Destination (Region): Converting a printer from one regional model to another (e.g., EU to US) to alter language, voltage defaults, or ink cartridge compatibility.
- Deep Cleaning & Nozzle Checks: Running more aggressive cleaning cycles than the standard driver allows.
- Retrieving Logs: Reading advanced error histories and usage logs.
Canon inkjet printers utilize internal firmware counters to track the volume of ink used for cleaning cycles and nozzle maintenance. This ink is absorbed by waste ink pads located at the base of the printer. When these counters reach their predefined limits, the printer enters a "Service Error" state (often indicated by error codes 5B00, 5B01, etc.) and ceases function. The Canon Service Tool v4905 is the industry-standard service utility designed to interface with the printer’s firmware to reset these counters and perform diagnostic operations.
Version 4905 is a critical iteration of the service tool suite, offering support for a wider range of modern Canon printer models compared to its predecessors (v3400, v3600, v4905). canon service tool 4905
