If the product is not responding correctly, complete the steps in the following checklist, in order. If the
product does not pass a step, follow the corresponding troubleshooting suggestions. If a step
resolves the problem, you can stop without performing the other steps on the checklist.
Troubleshooting checklist
1.
Make sure the product Ready light is on. If no lights are on, complete these steps:
a.
Check the power-cable connections.
b.
Check that the power is turned on.
c.
Make sure that the line voltage is correct for the product power configuration. (See the label
that is on the back of the product for voltage requirements.) If you are using a power strip
and its voltage is not within specifications, plug the product directly into the wall. If it is
already plugged into the wall, try a different outlet.
d.
If none of these measures restores power, contact HP Customer Care.
2.
Check the cabling.

Check the cable connection between the product and the computer or network port. Make
sure that the connection is secure.

Make sure that the cable itself is not faulty by using a different cable, if possible.

Check the network connection.

Check to see if any messages appear on the control-panel display. If any error messages
appear, see

6.
If the configuration page prints, check the following items:
a.
If the page does not print correctly, the problem is with the product hardware. Contact

computer you are using, with the printer driver, or with the program.
