Epson 900 User Manual page 59

To avoid damaging the printer, never move the print head by
hand. Don't open the clamp or remove a cartridge except to
replace it with a new one. Once you remove a cartridge, you
can't reuse it, even if it contains ink.
5. Pull up the ink cartridge clamp. The cartridge
rises up from its holder.
6. Lift the cartridge out of the printer and
dispose of it carefully.
If ink gets on your hands, wash them thoroughly with soap
and water. If ink gets into your eyes, flush them immediately
with water.
7. Lower the new ink cartridge into its holder with
the label facing up and toward the back of the
printer.
8. Press down the ink cartridge clamp until it
locks in place.
9. If you need to replace the other ink cartridge,
repeat steps 4 through 8 before continuing with
step 10.
10. Press the R cleaning button and close the printer cover. The printer moves the
print head and begins charging the ink delivery system.
The P power light flashes, and the printer makes various sounds. Charging takes
about one minute. When it's finished, the Ppower light stops flashing and stays
on.
Never turn off the printer while the P power light is flashing,
unless the printer hasn't moved or made noise for more than
5 minutes.
