To replace a print cartridge:
1 Press the Power button to turn on the printer.
The Power light comes on.
2 Open the top cover.
The print cartridge cradle moves to an accessible position,
and the Resume
light flashes.
3 Grasp the top of the empty print cartridge, pull it toward you
until it pops loose. Lift the print cartridge out of the cradle
and discard it.
Keep new and used print cartridges out of the
reach of children.
4 Remove the replacement print cartridge from its packaging
and carefully remove the protective vinyl tape from the print
cartridge.
Do NOT touch the print cartridge ink nozzles or
copper contacts. Touching these part will result
in clogs, ink failure, and bad electrical connections. Also, do
NOT remove the copper strips; these are required electrical
contacts.
5 Place the replacement cartridge into its cradle. You must
insert both print cartridges for the printer to operate.
