Using and Caring for Your Print Cartridges 3
4 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.
5 Push the print cartridge firmly, straight down into the print cartridge cradle.
6 Close the cradle latch. When the latch is fully closed, you will hear a click.
7 Load plain white paper in the IN tray.
8 Plug in the power cord in the back of the printer.
9 Close the top cover.
10 If the Resume light continues to flash and if the cradles do not move to the
right side of the printer, remove and reinstall the print cartridges. Make sure the
print cartridges are pressed down into the cradles before you snap them
forward into positions. If the Resume
light continues to flash after you
reinstall the new print cartridge, check the part number on the print cartridge
to ensure you installed the correct one.
Do NOT touch the
ink nozzles.
Do NOT touch or
remove the copper
contacts.
