• If you are using a power strip, make sure the power strip is on. Or, try plugging the
HP Photosmart directly into a power outlet.
• Test the power outlet to make sure it is working. Plug in an appliance that you know works,
and see if the appliance has power. If not, then there might be a problem with the power
outlet.
• If you plugged the HP Photosmart into a switched outlet, make sure the switch is on. If it is
switched to on but still does not work, then there might be a problem with the power outlet.
Cause: You pressed the On button too quickly.
Solution: The HP Photosmart might not respond if you press the On button too quickly. Press
the On button once. It might take a few minutes for the HP Photosmart to turn on. If you press
the On button again during this time, you might turn the device off.
CAUTION:
Unplug the HP Photosmart from the power outlet and contact HP. Go to:
support. If prompted, choose your country/region, and then click Contact HP for information
on calling for technical support.
I connected the USB cable, but I am having problems using the HP Photosmart with
my computer
Cause: The USB cable was connected before the software was installed. Connecting the USB
cable before prompted can cause errors.
Solution: You must first install the software that came with the HP Photosmart before
connecting the USB cable. During installation, do not plug in the USB cable until prompted by
the onscreen instructions.
Once you have installed the software, connecting your computer to the HP Photosmart with a
USB cable is straightforward. Simply plug one end of the USB cable into the back of your
computer and the other into the back of the HP Photosmart. You can connect to any USB port
on the back of your computer.
