Restoring Chipless Firmware on Epson WF2750
Introduction
I have an Epson WF2750 that I successfully installed the chipless firmware operation causing the ink cartridges to report permanently full. Then I decided to check out the option ‘To restore chipless firmware paste saved Code to Recovery Code window and Click Recover button’ as advised in the WF2750 Chipless Manual.Firmware Downgrade Attempt
I tried to downgrade firmware to JP24G5 24/05/2016 via the WIC utility but the procedure did not complete successfully. The printer got locked in Recovery Mode. I managed to fix this by downloading and installing the Recovery Firmware ‘Recovery_wf2750.zip’.Restoration Attempt
I attempted to restore the chipless function using the recovery code but was unsuccessful even after multiple attempts. I wanted to ensure the chipless restoration procedure works reliably.Recovery Code and Eprom Dump
Before using recovery code, chipless firmware has to be reloaded. The eprom dump can also be used to restore chipless function.Firmware Version and Release Date
Interestingly, the firmware version and release date did not change even after various attempts to restore chipless function. The printer remained at version JP0212.Questions and Conclusion
I seek advice on different methods of restoring chipless function and whether the eprom dump can be used on another WF2750 printer. Thank you for reading.Contact Admin
