Does an “E-mail gateway not
responding” message appear
on the control panel?
 Are you able to change the
“From” e-mail address?The device might be configured
so that the “From” e-mail
address cannot be changed.
The device might require you to
sign in before you can change
the “From” e-mail address.Use the embedded Web server
to change these settings. See
Embedded Web server.
 Are you able to change the file
type or the color setting for e-

accessory is installed
correctly and that none of
the pins are bent. See
Install the fax accessory .
2. Print a configuration page
and check the modem
status. It should indicate
“Operational/Enabled”. If
the modem status is
anything else, the problem
is with the fax accessory.

							SymptomCheckPossible causesPossible solutions
 Is the Fax feature configured
correctly but you cannot send
faxes?You must use the phone cord
that came with the device.
The phone cord might not be
connected securely or the
telephone line might not be
working.
You might have connected the
device to a digital phone line
instead of an analog phone line.
The fax accessory requires an
analog phone line.See Solve fax problems .
1. Always use the phone
cord that came with the
device.
2. Test the telephone line by
connecting a telephone to
it and making a call.
3. Make sure you are
connecting the device to
an analog phone line.
 Is  the Fax feature configured
correctly but you cannot receive
faxes? A line splitter or surge-
protection device might be
interfering with incoming faxes.
An answering machine or voice-
mail system might be
intercepting the incoming fax
transmission.See Solve fax problems
.
1. Do not use line splitters or
surge-protection devices.
2. Disconnect the answering
machine or voice-mail
system.
3. Set the number of rings-to-
answer for the fax
accessory to a lower
number. See 
Initial Setupmenu .
4. Make sure the device is
connected to an a
dedicated analog phone
line. Do not use a roll-over

							Solve general device problems
Device selects media from the wrong tray.
Cause
Solution
The tray selection in the software program might be incorrect.For many software programs, the paper tray selection is
found on the Page Setup menu within the program.
Remove any media in other trays to make the device select
from the correct tray.
For Macintosh computers, use the HPPrinter Utility to
change the priority of the tray.
The configured size does not match the size of the media
that is loaded in the tray. Adjust the width guides to match the size of the media that is
loaded in the tray.
Device does not pull paper from tray.
Cause
Solution
The tray is empty.Load paper in the tray.
The paper guides are set incorrectly.
To set the guides correctly, see Load media.
For tray2, 3, 4, or 5, make sure that the leading edge of the
paper stack is even. An uneven edge can prevent the lift
plate from rising.
Paper curls when it exits the device.
Cause
Solution
The paper curls when it exits to the top output bin. Choose the straightest paper path in the printer driver or
control panel.
Turn over the paper that you are printing on.
Reduce the fusing temperature to reduce the curling. (See
Print Quality menu .)
174 Chapter 11   Problem solving ENWW
 
						

							Print job is extremely slow.
Cause
Solution
The job might be very complex.
The maximum speed of the device cannot be exceeded
even when more memory is added.
Printing speeds might be automatically reduced when
printing on custom-sized media.
Note: Slower speeds are expected when printing on narrow
paper, when printing from tray 1, or when using the High2
fuser mode.Reduce the complexity of the page or try adjusting the print-
quality settings. If this problem occurs frequently, add
memory to the device.
You are printing a PDF or PostScript (PS) file but are using
a PCL device driver. Try using the PS device driver rather than the PCL device
driver. (You can usually do this from a software program.)
Print job prints on both sides of the paper. 
Cause
Solution
The device is set for duplexing.
See Open the printer drivers to change the setting, or see
the online Help.
Print job contains only one page but the device processes the  back side of the page as well (the page comes part
of the way out, and then goes back into the device).
Cause
Solution
The device is set for duplexing. Even if the print job contains
only one page, the device also processes the back side. See Open the printer drivers
 to change the setting, or see
the online Help.
Do not try to pull the page out of the device before duplexing
is complete. Jamming might result.
Pages print, but are totally blank.
Cause
Solution
The sealing tape might still be on the print cartridge.Remove the print cartridge and pull out the sealing tape.
Reinstall the print cartridge.
The file might have blank pages. Check the file to make sure that it does not contain blank
pages.
The device prints, but the text is wrong, garbled, or incomplete.
Cause
Solution
The device cable is loose or defective. Disconnect the device cable and reconnect it. Try a print job
that you know works. If possible, attach the cable and device
to another computer and try a print job that you know works.
Finally, try a new cable.

							The device prints, but the text is wrong, garbled, or incomplete.
Cause
Solution
The wrong driver was selected in the software.Check the software device selection menu to make sure that
an HP LaserJet M4345 device is selected.
The software program is malfunctioning.Try printing a job from another program.
The device does not respond when you select Print in the software. 
Cause
Solution
The device is out of media.Add media.
The device might be in the manual-feed mode.Change the device from manual-feed mode.
The cable between the computer and the device is not
connected correctly.Disconnect and reconnect the cable.
The device cable is defective.If possible, attach the cable to another computer and print a
job that you know works. You might also try using a different
cable.
The wrong device was selected in the software.Check the software device selection menu to make sure that
an HP LaserJet M4345 device is selected.
The device might have a jam.Clear any jams, paying careful attention to the duplexer area
(if your model has a duplexer). See Clear jams.
The software for the device is not configured for the device
port.Check the software device selection menu to make sure that
it is using the correct port. If the computer has more than
one port, make sure that the device is attached to the
correct one.
The device is on a network and is not receiving a signal.Check cable connections. Reinstall the printing software.
Print a job that you know works.
Clear any stopped jobs from the print queue.
The device is not receiving power.If no lights are on, check the power cord connections. Check
the power switch. Check the power source.
The device is malfunctioning. Check the control-panel display for messages and lights to
determine if the device is indicating an error. Note any
message and see 
Control-panel messages .
176 Chapter 11   Problem solving ENWW
 
						

							Control-panel message types
Four types of control-panel messages can indicate the status of or problems with the device.
Message typeDescription
Status messagesStatus messages reflect the current state of the device. They inform you of normal device
operation and require no interaction to clear them. They change as the state of the device
changes. Whenever the device is ready, not busy, and has no pending warning messages, the
status message Ready appears if the device is online.
Warning messagesWarning messages inform you of data and print errors. These messages typically alternate with
the Ready or status messages and remain until you touch  OK. Some warning messages are
clearable. If Clearable Warnings  is set to Job on the device  Device Behavior  menu, the next print
job clears these messages.
Error messagesError messages communicate that some action must be performed, such as adding paper or
clearing a jam.
Some error messages are auto-continuable. If  Auto-Continue is set on the menus, the device will
continue normal operation after an auto-continuable error message appears for 10 seconds.
NOTE Pressing any button during the 10-second auto-continuable error message
overrides the auto-continue feature, and the button function takes precedence. For
example, pressing the  Stop button pauses printing and offers the option to cancel the print
job.
Critical-error messages Critical error messages inform you of a device failure. Some of these messages can be cleared by turning the device off and then on. These messages are not affected by the  Auto-Continue
setting. If a critical error persists, service is required.
