Troubleshooting checklist

Make sure that the product is set up correctly.
Press the power button to turn on the product or to deactivate the Auto-Off mode.
Check the power-cable connections.
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.
Make sure that the print cartridge is installed correctly.
If none of these measures restores power, contact HP Customer Care.
Check the cabling or wireless connection (wireless models only).
Check the cable connection between the product and the computer. Make sure that the connection is secure.
Make sure that the cable itself is not faulty by using a different cable, if possible.
For a wireless connection, look at the control panel wireless light.

If the light is on, the product has a connection with a network.

If the light is blinking, the product is searching for a network connection. Make sure that the wireless router or access point and the product are set to use the same mode or protocol.

If the light is off, the product is not connected to the network and the wireless unit in the product might be off. Press the wireless button to try connecting to the network, or run the Wireless Configuration utility to configure the product. See Use the Wireless Configuration utility. To verify that the product finds the network, print a configuration page. The product should have an IP address assigned to it.

If the product remains unable to connect to the network, uninstall and then reinstall the product. If the error persists, contact a network administrator or refer to the user manual of the wireless router or access point.

Check to see if any control-panel lights are lit. See Interpret control-panel light patterns.
Make sure that the paper that you are using meets specifications.
Make sure that the paper is loaded correctly in the input tray.
Make sure that the product software is installed correctly.
Verify that you have installed the printer driver for this product. Check the program to make sure that you are using the printer driver for this product.
Print a configuration page. See Print the information pages.
If the page does not print, verify that the input tray contains paper.
If the page jams in the product, see Clear jams.
Print a small document from a different program that has worked in the past. If this solution works, then the problem is with the program you are using. If this solution does not work (the document does not print), complete these steps:
Try printing the job from another computer that has the product software installed.
Check the USB cable connection. Direct the product to the correct port, or reinstall the software, selecting the connection type that you are using.
If the print quality is unacceptable, complete the following steps:

Verify that the print settings are correct for the media that you are using. See Change the print driver to match the media type and size.

Use the procedures in Solve image-quality problems to solve print-quality problems.
