Finding the source of your problem
1. Look at the front-panel display for messages. See Message descriptions for a full explanation of front-panel
messages.
2. Test the printer.
– Switch the printer off on the front of the printer. Make sure that the power cord is firmly inserted in the
printer and plugged in to an outlet that you know works.
– Switch the printer on and make sure the front-panel display shows the HP welcome screen followed by
Main Menu after a short initialization period.
3. Test your computer hardware and interface.
– Make sure that you have the correct interface cable between the computer and the printer and that it is
firmly connected to the correct ports (see the Assembly and Set-up Poster).
