When I connected
a USB cable
between the printer
and my computer,
the New Hardware
Wizard appeared
once, but the printer
did not install
completely. Now
the New Hardware
Wizard will not
appear again.
Installation was not
completed, it was
cancelled, or there
was an error.
Try the following:
1 Disconnect the USB cable from your
computer.
2 Unplug the power cord from the
printer, then plug it in again.
3 Uninstall the printer software. Insert the
printer software CD into your computer,
click Remove HP Photosmart software,
then follow the instructions on your
computer screen.
4 When the uninstall is completed, restart
your computer.
5 Reconnect the USB cable to your
computer. Make sure the cable is
securely attached to the USB port on
the back of the printer.
6 Reinstall the printer software. For
instructions, see the Software Setup &
Product Support booklet.
