Troubleshooting with control-panel messages
Printer messages appear on the printer control panel display to relay the normal status of the
printer (such as Processing job) or an error condition (such as CLOSE FRONT DOOR) that needs
attention. “Interpreting control-panel messages” on page 186 lists the most common messages
that require attention or that might raise questions. Messages are listed in alphabetical order
first, with numeric messages at the end of the list.
Using the printer online Help system
This printer features an online Help system on the control panel that provides instructions for
resolving most printer errors. Certain control panel messages alternate with instructions about
gaining access to the online Help system.
Whenever a message alternates with FOR HELP PRESS ?, press (
HELP) to view the help and
use (
UP arrow) and (DOWN arrow) to scroll through the message.
To exit the online Help system, press (
HELP). For more information on control panel features,
see “Control panel” on page 52.
Resolving persistent messages
Some messages (for example, requests to load a tray or a message that a previous print job is
still in the printer memory) allow you to press (
SELECT) to print, or to press CANCEL JOB to clear
the job and eliminate the message.
If a message persists after performing all of the recommended actions, contact an HP-authorized
service or support provider. (See “Ordering parts and supplies and getting support” on page 242
or go to http://www.hp.com/support/lj2300.)
