Unpack
Note: This product requires careful handling of ink. If ink spills, wipe it
off immediately with a damp towel to avoid permanent stains. If ink gets
on your clothes or belongings, it may not come off.
Warning: Keep the ink bottles out of the reach of children and do not
drink the ink.
1 Open the ink tank cover, then open the cap for the ink tank
you are going to fill.
2 Unpack one of the ink bottles. Hold the ink bottle upright
and slowly turn the bottle cap to remove it.
Note: Do not open the ink bottles until you are ready to fill the ink
tanks. The ink bottles are vacuum packed to maintain reliability.

2 Lift up the scanner unit. Remove all protective materials
from inside the product.
Caution: Do not shake or squeeze the ink bottles. Do not touch

3 Position the top of the ink bottle along the slot in front of
the filling port, then slowly stand the bottle up to insert it.
Note: Refer to the color-coded sticker to identify the color of
each tank. Do not force the bottles into position; they are keyed
for each color.

Ink flows into the tank and stops automatically when the
