The ink lamp is off.
The ink tank is not installed properly or the function for detecting the remaining ink level is
disabled. If the ink tank is not firmly in place, make sure that the orange protective cap has been
removed from the bottom of the ink tank, then press on the top of the ink tank until the ink tank
clicks into place.
If the ink lamp is still off after reinstalling the ink tank, there has been an error and the printer
cannot print. Check the Alarm lamp on the printer.
