							Solution:If you did not load an original in the document feeder tray, or if the original
is not pushed in far enough, you will be unable to send a fax manually. Load an original
in the document feeder tray, or push the original farther into the tray. Once the HP All-
in-One detects the original, a confirmation message appears on the display.
Pages of a fax I sent are missing
Cause:Two or more pages were fed through the document feeder tray at the same
time.
Solution:Print a Last Transaction report to verify the number of pages that were
sent. If two or more pages stuck together and were fed into the document feeder tray
at the same time, the number of pages in the report would not match the actual
number of pages. If the number of pages listed in the report does not match the actual
number of pages, you might need to clean the separator pad in the automatic
document feeder.
To print a Last Transaction report
1.Press Setup, and then press 2.
This selects Print Report.
2.Press 
 to select Last Transaction, and then press OK.
For more information on cleaning the separator pad, see 
Clean the automatic
document feeder.
Cause:The receiving fax machine is having problems.
Solution:To check this, try calling the fax number from a telephone and listen for
fax tones. If you cannot hear fax tones, the receiving fax might not be turned on or
connected, or a voice mail service could be interfering with the recipients phone line.
The memory of the receiving fax machine might be full or the fax machine might have
run out of paper. You can ask the recipient to check the receiving fax machine for any
problems.
Cause:The phone line connection is noisy. Phone lines with poor sound quality
(noise) can cause faxing problems.
Solution:If the failure was due to noise on the phone line, contact the sender to
have them resend the fax. The quality might be better when you try again. You can
check the sound quality of the phone line by plugging a phone into the telephone wall
jack and listening for static or other noise. If the problem persists, turn Error
Correction Mode (ECM) off and contact your telephone company.
To change the ECM setting from the control panel
1.Press Setup.
2.Press 5, and then press 6.
This selects Advanced Fax Setup and then selects Error Correction Mode.
3.Press 
 to select On or Off.

							Cause:The glass of the HP All-in-One might be dirty.
Solution:If you are sending a fax from the glass, make a copy to check the quality
of the printout. If the quality of the printout is poor, clean the glass.
To make a copy from the control panel
1.Make sure you have paper loaded in the input tray.
2.Load your original print side down on the right front corner of the glass or print
side up in the document feeder tray.
If you use the document feeder tray, place the pages so that the top edge of the
document goes in first.
3.Do one of the following:
•Press Start Copy Black to initiate a black-and-white copy job.
•Press Start Copy Color to initiate a color copy job.
NOTE:If you have a color original, pressing Start Copy Black produces a

produces a full-color copy of the color original.
To clean the glass
1.Turn off the HP All-in-One, and raise the lid.
2.Clean the glass with a soft cloth or sponge slightly moistened with a nonabrasive
glass cleaner.
CAUTION:Do not use abrasives, acetone, benzene, or carbon tetrachloride
on the glass, since they can damage it. Do not place or spray liquid directly
on the glass. The liquid might seep under the glass and damage the device.
3.Dry the glass with a dry, soft, lint-free cloth to prevent spotting.
4.Turn on the HP All-in-One.
Cause:The receiving fax machine is having problems.
Solution:To check this, try calling the fax number from a telephone and listen for
fax tones. If you cannot hear fax tones, the receiving fax might not be turned on or
connected, or a voice mail service could be interfering with the recipients phone line.
You can also ask the recipient to check the receiving fax machine for any problems.
Cause:The Lighter / Darker setting might be set too light. If you are sending a
faded, washed out, or handwritten fax, or a document with a watermark (such as a
red seal or stamp), you can change the Lighter / Darker setting to send the fax darker
than the original.

Parts of a fax I sent are cut off
Cause:The fax is larger than letter or A4 paper.
Solution:Some fax machines cannot accept faxes larger than letter or A4 paper.
Make sure the receiving fax machine can accept the paper size you are using. If not,
ask the recipient if the receiving fax machine has a fit to page setting they can use to
reduce the incoming fax to fit standard paper size such as letter or A4.
The fax I sent was blank when it was received
Cause:The original was not loaded or was loaded incorrectly.

Fax transmission is slow
Cause:You are sending a fax in color.
Solution:Sending a fax in color can take longer than sending a black-and-white
fax. Try sending the fax in black and white.
Cause:The document contains a lot of graphics or has very fine detail.
Solution:For faster transmission, use Standard resolution. This setting provides
the fastest possible transmission with the lowest quality of fax. The default resolution
is Fine, which can take longer to send.
To change the resolution from the control panel

The HP All-in-One cannot receive faxes, but can send faxes
Cause:The HP All-in-One is not set up properly for faxing.
Solution:Follow the instructions to set up the HP All-in-One properly for faxing,
based on the equipment and services you have on the same phone line as the HP All-
in-One. Then, run a fax test to check the status of the HP All-in-One and to make sure
you set it up properly. For more information, see 
Set up the HP All-in-One for
faxing.
The HP All-in-One prints a report with the results of the test. If the test fails, review
the report for information on how to fix the problem.
To test your fax setup from the control panel

setup instructions.
2.Insert the print cartridges and load full-size paper in the input tray before starting
the test.

This selects the Tools menu and then selects Run Fax Test.
The HP All-in-One displays the status of the test on the display and prints a report.
5.Review the report.
• If the test passes and you are still having problems faxing, check the fax
settings listed in the report to verify the settings are correct. A blank or
incorrect fax setting can cause problems faxing.
• If the test fails, review the report for more information on how to fix any
problems found.
6.After you pick up the fax report from the HP All-in-One, press OK.
If necessary, resolve any problems found and rerun the test.

							Cause: Auto Answer is turned off, which means that the HP All-in-One will not
answer incoming calls. You must be available to respond in person to incoming fax
calls, or the HP All-in-One will not answer the incoming fax call.
Solution:Depending on your office setup, you might be able to set the HP All-in-
One to answer incoming calls automatically. To find out what the recommended
answer mode is for your office setup, see 
Choose the recommended answer mode
for your setup.
If you must have Auto Answer off, you will need to press Start Fax Black or Start
Fax Color to receive a fax.
TIP:If you are not close enough to the HP All-in-One to reach the control panel,
wait several seconds, and then press 1 2 3 on your phone. If the HP All-in-One
does not begin receiving the fax, wait several more seconds and press 1 2 3 again.
After the HP All-in-One begins to receive the fax, you can hang up the phone.
Cause:You subscribe to a voice mail service at the same phone number you use
for fax calls.
Solution:Set the HP All-in-One to answer faxes manually. You cannot receive
faxes automatically if you have a voice mail service at the same phone number you
use for fax calls. You must receive faxes manually; this means you must be available
to respond in person to incoming fax calls.
For more information on how to set up the HP All-in-One when you have a voice mail
service, see 
Set up the HP All-in-One for faxing.
Cause:You have a computer dial-up modem on the same phone line as the HP All-
in-One.
Solution:If you have a computer dial-up modem on the same phone line as the
HP All-in-One, check to make sure that the software that came with your modem is
not set to receive faxes automatically. Modems that are set up to receive faxes
automatically take over the phone line to receive all incoming faxes, which prevents
the HP All-in-One from receiving fax calls.
Cause:If you have an answering machine on the same phone line with the HP All-
in-One, you might have one of the following problems:
•Your outgoing message might be too long or too loud to allow the HP All-in-One
to detect fax tones, and the sending fax machine might disconnect.
•Your answering machine might not have enough quiet time after your outgoing
message to allow the HP All-in-One to detect fax tones. This problem is most
common with digital answering machines.
