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.
1 Remove all protective materials from the product.
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.
4 Wait for the ink to fill the tank. Do not squeeze the bottle.
Ink flows into the tank and stops automatically when the
ink is filled to the upper line.
Caution: Do not touch the flat white cable or the ink tubes and
their translucent cover.
Note: If ink does not flow from the bottle, lift and reinsert the
bottle.
