Understanding printer 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 89 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 (H
ELP button) to view the help
and use (U
P button) and (DOWN button) to scroll through the message.
To exit the online Help system, press (H
ELP button).
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 (S
ELECT button) to print, or to press CANCEL
J
OB 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 “Contacting HP” on page 123 or go to http://www.hp.com/
support/lj2300.)
