Prevent copy problems
The following are a few simple steps you can take to improve copy quality:
●Copy from the flatbed scanner. This will produce a higher quality copy than copying from the
automatic document feeder (ADF).
● Use quality originals.
● Load the media correctly. If the media is
 loaded incorrectly, it might skew, causing unclear
images and problems with the OCR program. See 
Load media  for instructions.
● Use or make a carrier sheet to protect your originals.
NOTE
Verify that the media meets HP specifications. If the media meets HP specifications,
recurring feed problems indicate the pickup roller or separation pad is worn. Contact
HP Customer Care. See 
HP Customer Care  or the flyer that came in the device box.

Poor print quality or toner adhesionThe paper is too moist, too rough, too
heavy or too smooth, or it is embossed
or from a faulty paper lot.Try another kind of paper, between 100
and 250 Sheffield, 4 to 6% moisture
content.
Dropouts, jamming, or curlThe paper has been stored incorrectly.Store paper flat in its moisture-proof
wrapping.
The paper has variability from one side
to the other.Turn the paper over.
Excessive curlThe paper is too moist, has the wrong
grain direction, or is of short-grain
constructionOpen the rear output bin, or use long-
grain paper.
The paper varies from side-to-side.Turn the paper over.

and try printing again.
The scanner might require a calibration.Perform a tray alignment, and then
calibrate the scanner.
●Perform a tray alignment by
opening the 
Administration menu
at the device control panel. On the
Print Quality  submenu, touch Set
Registration . Choose a tray under
Source  and then run a test page.

							Solve fax problems
Solve sending problems
Faxes quit during sending.
Cause
Solution
The fax machine to which you are sending might be
malfunctioning.Call the recipient to make sure that the receiving fax
machine is turned on and ready to receive faxes, or try
sending to another fax machine.
Your telephone line might not be working, or the line might
be experiencing interference.Disconnect the fax cable from the telephone jack, and then
connect a telephone. Make a phone call to ensure that the
telephone line is working.
Try using a lower baud rate by adjusting the Maximum Baud
Rate setting in the Administration menu. See 
Initial Setupmenu
.
The device fax is receiving faxes but is not sending them.
Cause
Solution
If the device is on a PBX system, the PBX system might be
generating a dial tone that the fax cannot detect.Disable the detect dial tone setting. See the fax guide for
information about changing the setting.
There might be a poor telephone connection.Resend the fax later.
The fax machine to which you are sending might be
malfunctioning.Call the recipient to make sure that the receiving fax
machine is turned on and ready to receive faxes, or try
sending to another fax machine.
Your telephone line might not be working. Disconnect the fax cable from the telephone jack, and then
connect a telephone. Make a phone call to ensure that the
telephone line is working.
Outgoing fax calls keep dialing.
Cause
Solution
The fax automatically redials a fax number if either the
Redial on Busy feature or the Redial on No Answer feature
is enabled. Disable the Redial on Busy and Redial on No Answer
features. See the fax guide for information about changing
the settings.

							Faxes you send are not arriving at the receiving fax machine.
Cause
Solution
The receiving fax machine might be turned off or might have
an error condition, such as being out of paper.Call the recipient to make sure that the fax machine is
turned on and ready to receive faxes.
A fax might be stored in memory because it is waiting to
redial a busy number, or there are other jobs ahead of it
waiting to be sent.If a fax job is in memory for either of these reasons, an entry
for the job appears in the fax log. Print the fax activity log
(see the fax guide), and check the 
Result column for jobs
with a Pending  designation.
NOTEIf the fax is sending very slowly, see Faxes are transmitting or being received very
slowly in 
Initial Setup menu .
Solve receiving problems
Incoming fax calls are not being answered by the fax (no fax detected).
Cause
Solution
The rings-to-answer setting might not be set correctly.Check the rings-to-answer setting. See the fax guide for
information about changing the setting.
The telephone cord might not be connected properly, or the
telephone cord is not working.Check the installation. Make sure you are using the
telephone cord that came with the device.
The telephone line might not be working.Disconnect the fax cable from the telephone jack, and then
connect a telephone. Make a phone call to ensure that the
telephone line is working.
A voice-messaging service might be interfering with the
ability to answer calls. Do one of the following:
●
Discontinue the messaging service.
● Get a telephone line dedicated to fax calls.
● Decrease the rings-to-answer setting for the fax to a
number less than the rings-to-answer for the voice
mail. See the fax guide for information about changing
the setting.
Faxes are transmitting or being received very slowly.
Cause
Solution
You might be sending or receiving a very complex fax, such
as one with many graphics.Complex faxes take longer to be sent or received.
The receiving fax machine might have a slow modem speed. The device fax only sends the fax at the fastest modem
speed the receiving fax machine can use.
224 Chapter 11   Problem solving ENWW
 
						

							Faxes are transmitting or being received very slowly.
Cause
Solution
The resolution at which the fax was sent or is being received
is very high. A higher resolution typically results in better
quality, but also requires a longer transmission time.If you are receiving the fax, call and ask the sender to
decrease the resolution and resend the fax. If you are
sending, decrease the resolution or change the Page
Content mode setting. See the fax guide for information
about changing the settings.
A poor telephone-line connection is forcing the device fax
and the sending or receiving fax machine to slow down the
transmission to adjust for errors.Cancel and resend the fax. Have the telephone company
check the telephone line.
Faxes are not printing at the device.
Cause
Solution
There is no media in the input trays.Load media. Any faxes received while the input trays are
empty are stored and will print after the trays have been
refilled.
The Schedule Printing of Faxes mode is enabled. Faxes will
not print until it is disabledDisable the Schedule Printing of Faxes mode. See the fax
guide for information about changing the setting.
The device toner level is low, or it has run out of toner.
The device stops printing as soon as it is low on toner or
runs out of toner. Any faxes received are stored in memory
and are printed after the toner has been replaced.Replace the print cartridge.

							Solve e-mail problems
If you are unable to send e-mails by using the digital-send feature, you might need to reconfigure the
SMTP gateway address or the LDAP gateway address. Print a Configuration page to find the current
SMTP and LDAP gateway addresses. Use the following procedures to check if the SMTP and LDAP
gateway addresses are valid.
Validate the SMTP gateway address
NOTEThis procedure is for Windows operating systems.
1.
Open an MS-DOS command prompt: click  Start, click Run, and then type  cmd.
2. Type  telnet  followed by the SMTP gateway address and then the number 25, which is the
port over which the MFP is communicating. For example, type  telnet 123.123.123.123
25 where 123.123.123.123 represents the SMTP gateway address.
3. Press  Enter. If the SMTP gateway address is  not valid, the response contains the message
Could not open connection to the host on port 25: Connect Failed.
4. If the SMTP gateway address is  not valid, contact the network administrator.
Validate the LDAP gateway address
NOTEThis procedure is for Windows operating systems.
1.
Open Windows Explorer. In the address bar, type  LDAP:// immediately followed by the LDAP
gateway address. For example, type  LDAP://12.12.12.12 where 12.12.12.12 represents
the LDAP gateway address.
2. Press  Enter. If the LDAP gateway address is valid, the  Find People dialog box opens.
3. If the LDAP gateway address is not valid, contact the network administrator.

Illegal Operation
Cause
Solution
Close all software programs, restart Windows, and try again.
Select a different printer driver. If the device PCL 6 printer
driver is selected, switch to the PCL 5 or HP postscript level
3 emulation printer driver, which can be done from a
software program.
Delete all temp files from the Temp subdirectory. Determine
the name of the directory by opening the AUTOEXEC.BAT
file and looking for the statement Set Temp =. The name
after this statement is the Temp directory. It is usually C:
\TEMP by default, but can be redefined.
