Tool Version 1.050 | Canon Service Mode

: Use version 1.050 only if you have an older model, a dedicated offline PC, and the technical confidence to handle potential EEPROM corruption. For everyone else, weigh the cost of a new printer against the frustration of troubleshooting service mode communication errors.

: If you attempt to enter Service Mode incorrectly too many times, or use an incompatible version of the tool, you can "lock" the printer's firmware, making it impossible to enter Service Mode again without replacing the logic board. Physical Maintenance Canon service mode tool version 1.050
