Maintenance Box can not be reset or deactivated by firmware.

Chipless firmware is for making ink cartridges always full. Not Maintenance cartridge.

You can reset it by hardware Chip Resetter

To restore chipless firmware back after updating from epson - you need to have Recovery Code.
You have to save Recovery Code when using License utility

Incase you forgot to save your recovery codes, pls use wic reset program to save your  eeprom.

Then 

you can reset it when printer has original epson firmware

so update it to epson firmware
reset chip
then uploads chipless firmware back again and restore your chipless eeprom

I have an urgent question regarding Epson reset keys.

They are valid, but cannot reset a printer.

Once you reset, it says key has been used to reset the target printer.

But in reality printer has not been reset.

My question is, could the keys be blacklisted?
