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.

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
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 "Prepare the replacement tank." on page 110.
If the function for detecting the remaining ink level is disabled, replace the ink tank with a new
one. See "Replacing Ink Tanks" on page 109.
If the lamps are still off after reinserting the ink tanks, there has been an error and the
