1 Unpack
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.
2Lift up the scanner unit. Remove all protective materials from inside the product.
Caution: Do not touch the flat white cable or the ink tubes and their translucent cover.
2 Fill ink tanks
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.
1Open the ink tank cover, then open the cap for the ink tank you are going to fill.
2Unpack one of the ink bottles. Hold the ink bottle upright and slowly turn the bottle cap to remove it.
Caution: Do not shake or squeeze the ink bottles. Do not touch the top of the ink bottle after its cap is removed.
3Position 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.
4Wait 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.
Note: If ink does not flow from the bottle, lift and reinsert the bottle.
5When the ink tank is full, remove the ink bottle and securely close the ink tank cap. Place the remaining ink aside; you will need it later.
Note: Replace the bottle cap and tighten it.
