HP CC487-91209 Fax Manual page 58

Incoming fax calls are not being answered by the fax accessory (no fax detected).
Cause
The phone cord might not be connected properly, or the
phone cord is not working.
The phone line might not be working.
A voice-messaging service might be interfering with the fax
accessory's ability to answer calls.
Faxes are transmitting or being received very slowly.
Cause
Either the sending fax machine or the receiving fax machine
has a slower speed setting.
You might be sending or receiving a very complex fax, such
as one with many graphics.
The receiving fax machine might have a slow modem speed.
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 there is a poor phone-line connection, the fax accessory
and the receiving fax machine slow down the transmission to
adjust for errors.
Faxes are not printing on the product.
Cause
There is no media in the media input tray.
Schedule Printing of Faxes is set.
The product is either low on toner or has run out of toner.

Solution
Check the installation. Make sure you are using the phone
cord that came with the fax accessory.
Disconnect the fax accessory from the phone jack, and
connect a phone. Try to make a phone call to ensure the
phone line is working.
Do one of the following:
Discontinue the messaging service.
●
Get a phone line dedicated to fax calls.
●
Decrease the rings-to-answer for the fax accessory to a
●
number less than the rings-to-answer for the voice mail.
Solution
The fax can only be transmitted as fast as the slowest speed
setting by both the sending and receiving fax machines. For
example, the receiving machine might be set at 33,000 bps,
but if the sending machine is only set to 14,400 bps, the fax
is only transmitted at 14,400 bps.
Complex faxes take longer to be sent or received.
The fax accessory only sends the fax at the fastest modem
speed the receiving fax machine can use.
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 and change the
Text/Picture option.
Cancel and resend the fax. Have the phone company check
the phone line.
Solution
Load media. Any faxes received while the input tray is empty
are stored and will print after the tray has been refilled.
If Schedule Printing of Faxes is enabled, faxes will not print
until it is disabled.
The product stops printing as soon as it is low on toner or
runs out of toner. Any faxes received are stored in memory
and print after the toner has been replaced. For other
product printing problems, see the product user guide.
