6-2-1. Confirmation and disposal of waste ink
Check the amount of waste ink in the waste ink tank, and if the tank is filled with the waste ink up to its one-half or higher
level, discard the ink.
(1) Check on the waste ink tank, and discard the waste ink.
In an area under the other end of the waste ink tube (when removed) from the waste ink tank, place a receiving tray or the like so
that the waste ink spilled from the tube will not be discharged onto the floor, etc.
<NOTE>

Dispose of the waste ink properly as water-based waste fluid in accordance with applicable laws and ordinances.

(2) Return the waste ink tank to its original state, and insert the waste ink tube into the tank.
<IMPORTANT>

The waste ink tube should be cut diagonally. If the tip of the waste ink tube is immersed in the liquid, it will prevent the
smooth flow of the waste ink, to disable the ink suction operation of the head cleaning function. Otherwise, waste fluid may
flow reversely, causing the waste ink to spill contaminating the floor.

Avoid placing the waste ink tube horizontally as much as possible, and be sure not to let it bend.
Otherwise the waste ink may have difficulty flowing through the tube.
