Canon PIXMA G3501 Service Mode Failure: Troubleshooting and Solutions

Unplugging as a Quick Fix:

In response to Gauthier's predicament, community member James suggested a common yet effective approach: unplugging the printer for 30 minutes to a day. This solution aims to address a potential freeze in service mode, and indeed, Gauthier reported success as the printer came back to life after the prescribed period.

Additional Steps for Service Mode Entry: 

James also advised retrying the entry into service mode if the printer boots up in normal mode after the unplugging. However, if issues persist, it may indicate a need for reprogramming the printer's EEPROM, a more intricate process.

Another user shared insights, suggesting a cautious approach when using a PC for counter resets and recommending checking software compatibility. Moreover, the discussion delved into the importance of waste pad replacement and the associated ink counter reset procedures.

Service Manuals:

These manuals highlighted the significance of using the correct service tool version for different printer models, with mentions of V4718 for G1000-G2000-G3000 and V4904 for G4000.

Firmware Considerations and WIC Reset Tool: 

The exchange also touched upon firmware versions, emphasizing their role in push-button service mode availability. It was suggested that outdated firmware might hinder this functionality. Additionally, users explored alternative reset methods, such as the WIC Reset tool, which requires a small investment but could be a viable solution for those seeking alternatives.
