Using and Caring for Your Print Cartridges
3
To replace a print cartridge:
1 Press the Power Button to turn on the
printer. The print cartridges move.
2 Unplug the power cord from the back
of the printer.
3 Open the top cover and raise the cradle
latch.
4 Lift the print cartridge out of the cradle
and discard it.
Keep print cartridges out of the reach of children.
5 Remove the replacement print cartridge from its packaging and carefully
remove the protective vinyl tape.
Do NOT touch the print cartridge ink nozzles or copper contacts. Touching
these parts will result in clogs, ink failure, and bad electrical connection.
Also, do NOT remove the copper strips; these are required electrical
contacts.
6 Push the print cartridge firmly, straight down into the print cartridge cradle.
7 Close the cradle latch. When the latch is fully closed, you will hear a click.
8 Load plain white paper in the IN tray.
9 Plug in the power cord in the back of the printer.
10 Close the top cover.
11 If the Print Cartridge Status Light continues to blink after you install the
new print cartridge, check the part number on the print cartridge to ensure you
installed the correct one.
