The ink tank is inserted in the wrong position or it is empty. Ensure that the ink tank is in the correct position as directed by the label on the Print Head Holder. If the position is correct and its lamp flashes, it is empty. Replace it with a new one.

- Ink lamp is off
The ink tank is not set properly or the function for detecting the remaining ink level is disabled.
If the ink tank is not set properly, press the mark on the ink tank until the tank clicks into place. If it does not click into place, make sure that the orange protective cap has been removed from the bottom of the ink tank. See [ Replacing Ink Tanks ].
If the function for detecting the remaining ink level is disabled, replace the ink tank with a new one. See [ Replacing Ink Tanks ].
If the lamps are still off after reinserting the ink tanks, there has been an error and the machine cannot print. Check the error message displayed on the LCD. See [ An Error Message Is Displayed on the LCD ].
