This printer has ink tanks (A) and sub-ink tanks (B). Even if ink runs out, printing can continue with ink in
the sub-ink tanks.
When the remaining ink is low, will appear on the remaining ink level. When ink runs out, will
appear. See the figure below.
If the touch screen indicates to replace the ink tank, replace the ink tank. If a message is displayed
indicating to check the remaining ink levels, or after tasks that consume a lot of ink such as large-format
printing or head cleaning, check the remaining levels and replace ink tank as needed.
