Question
Is the All-In-One on?
Do you see an error
message?
Is your All-In-One connected
to your computer through
another device, such as a
USB hub or switch box?
Did you remove the
transparent tape from the
bottom of each print
cartridge?
Are the print cartridges
installed properly?
Is the paper loaded
correctly?
Solution
Press the Power button. If
the Power light does not
come on, see the "The
Power light is not lit"
symptom at the beginning of
this table.
See "Understanding error
codes on the display" on
page 67.
Disconnect the USB cable
from any other devices and
directly connect it between
the All-In-One and your
computer.
Remove the print cartridges,
check for the transparent
tape and then reinsert them.
