HP Officejet Pro 8600 - Manual (Page 133)

• If the printer shares the same phone line with other types of phone
equipment, such as an answering machine, a computer dial-up modem, or
a multi-port switch box, the fax signal level might be reduced. The signal
level can also be reduced if you use a splitter or connect extra cables to
extend the length of your phone. A reduced fax signal can cause problems
during fax reception.
To find out if other equipment is causing a problem, disconnect everything
except the printer from the phone line, and then try to receive a fax. If you
can receive faxes successfully without the other equipment, one or more
pieces of the other equipment is causing problems; try adding them back
one at a time and receiving a fax each time, until you identify which
equipment is causing the problem.
• If you have a special ring pattern for your fax phone number (using
a distinctive ring service through your telephone company), make sure that
the Distinctive Ring feature on the printer is set to match. For more
information, see Change the answer ring pattern for distinctive ring.
The printer cannot send faxes, but can receive faxes
Solution:
•
The printer might be dialing too fast or too soon. You might need to insert
some pauses in the number sequence. For example, if you need to access
an outside line before dialing the phone number, insert a pause following
the access number. If your number is 95555555, and 9 accesses an outside
line, you might insert pauses as follows: 9-555-5555. To enter a pause in
the fax number you are typing, touch the Space (#) button repeatedly, until
a dash (-) appears on the display.
You can also send the fax using monitor dialing. This enables you to listen
to the phone line as you dial. You can set the pace of your dialing and
respond to prompts as you dial. For more information, see Send a fax using
monitor dialing.
• The number you entered when sending the fax is not in the proper format or
the receiving fax machine is having problems. 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 machine might not be turned on or connected, or
a voice mail service could be interfering with the recipient's phone line. You
can also ask the recipient to check the receiving fax machine for any
problems.
