Ink Tank Lamps

Slow flashing (about three seconds): Ink is low. Prepare a new ink tank. For details,
see
“Getting the Ink Level Information” on page 142 .
Fast flashing (about one second): Ink tank is empty, or the machine is not ready due to
an error.
Off: Make sure all the ink tanks are installed properly. If an Ink Tank Lamp remains unlit
even after reinstalling ink tanks, an error has occurred and the machine is not ready to
print.
