 
Understanding printer messages
The table in this section explains messages that might appear on the 
printer control panel. Printer messages and their meanings are listed 
in alphabetical order, with numbered messages following.
If a message persists:

If a message persists requesting that you load a tray, or if a 
message indicates that a previous print job is still in the printer’s 
memory, press

to clear the job
from the printer’s memory.
●
If a message persists after performing all of the recommended 
actions, contact an HP-authorized service or support provider 
(see “HP Customer Care Service and Support” on page 157).
Note
Not all messages are described in this user guide (many are self-
explanatory).
Some printer messages are affected by the Auto Continue and 
Clearable Warning settings from the Configuration Menu in the printer 
control panel (see the description of “
CLEARABLE WARNINGS=JOB

page 220).
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 on accessing the online 
help system.
Whenever a
?
appears in an error message or the message
alternates with

, press the right side of
the
I

ACCESS DENIED
MENUS LOCKED
The printer control panel function you are trying to access has been 
locked to prevent unauthorized access.
See your network administrator.
BAD DUPLEXER
CONNECTION
The duplexer is not properly connected to the printer.
Ensure that the right-angle power cord that shipped with the printer 
is being used.
Try removing and reinstalling the duplexer. Then turn the printer off 
and back on.
BAD ENV FEEDER
CONNECTION
The envelope feeder is not connected properly to the printer.
Try removing and reinstalling the envelope feeder. Then turn the 
printer off and back on.
BAD OPT TRAY
CONNECTION
There is a problem with an optional 500-sheet paper tray connection 
with the printer:
• the tray is not connected properly
• more than two optional 500-sheet paper trays have been installed
(the printer cannot support more than four trays total)
• the electronics in the paper tray are faulty
Try removing and reinstalling the paper tray. Then turn the printer off 
and back on.

MEMORY FULL
STORED DATA LOST
There is no available memory in the printer. The current job might not 
print correctly and some resources (such as downloaded fonts or 
macros) might have been deleted.
Consider adding more memory to the printer (see “Printer memory 
and expansion” on page 229).
MEMORY SETTINGS
CHANGED
The printer changed its memory settings because it did not have 
enough memory to use the previous settings for I/O Buffering and 
Resource Saving. This usually occurs after removing memory from 
the printer, adding a duplexer, or adding a printer language. 
Consider adding more memory to the printer (see “Printer memory 
and expansion” on page 229).

Turn the printer off to keep the paper from wrapping more firmly 
around the fuser. Open the top cover and remove the toner cartridge. 
Remove all visible paper. If you cannot locate the paper, leave printer 
turned off and remove the fuser to remove paper (see “Clearing jams 
from the fuser area” on page 107).
PERFORM PRINTER
MAINTENANCE
To ensure optimum print quality, the printer prompts you to perform 
routine maintenance every 200,000 pages. (To order a printer 
maintenance kit, see “Ordering information” on page 22. For 
information on maintenance, see “Performing preventative 
maintenance” page 93.)
PRINTER LANGUAGE
NOT AVAILABLE

cartridge at 5% coverage). Depending on how the printer has been 
configured, it will either continue to print or stop. 
If the printer has stopped, you can resume printing by pressing

You might want to ensure that you have a replacement toner cartridge 
on hand.
See “Toner low and toner out conditions” on page 87 for information 
on how to configure the printer’s response to toner messages. 
TONER OUT
The toner cartridge has run out of toner. Depending on how the printer

If the message persists with different software applications and print 
jobs, disconnect all cables to the printer that connect it to the network 
or printer. Turn the printer off. Remove all memory DIMMs or third-
party DIMMs from the printer (see “Installing memory” on page 230). 
Remove all EIO devices from the printer (see “Installing EIO cards/
mass storage” on page 233). Turn the printer on. If the error no longer 
exists, install each DIMM and EIO device one at a time, making sure 
to turn the printer off and back on as you install each device. Replace 
a DIMM or EIO device if you determine that it causes the error. 
Remember to reconnect all cables that connect the printer to the 
network or computer.
