Because the printer will charge the ink delivery system after the ink cartridge is replaced again, this process will not work in the off state, so that the printer cannot detect the reinstalled ink cartridge.

When the counter reaches a certain value, the printer determines that the ink has run out. During the ink cartridge replacement process, the printer resets its internal electronic counter to confirm that a new ink cartridge is installed.
