You have encountered a warning message on the LCD screen that instructs you to change an ink cartridge and the Yellow ink cartridge, but the Yellow cartridge does not require replacement, AND:
The printer's firmware version is TT0886.
This warning message only appears if any combination of the Black, Cyan or Magenta ink cartridges have between 3% and 6% of their ink remaining AND you have tried to perform a Head Clean from the printer's control panel.
If you have not encountered the warning message under these specific circumstances then you do not need to apply the firmware update.
