Before print jobs and maintenance that consume a lot of ink
If little ink is left, there may not be enough for large-format printing, head cleaning, and maintenance, which require a lot of
ink. In this case, replace or prepare to replace the Ink Tank before maintenance.
If a message for ink replacement is shown on the Display Screen
When ink runs out, the Message Lamp flashes, a message regarding Ink Tank replacement is shown on the Display Screen,
and printing is disabled. Replace the Ink Tank at this point.
