Receiving fax problems
Use the table in this section to solve problems that might occur when 
receiving faxes.
Problem
Cause
Solution
Unable to start 
receiving faxes from an 
extension phone. 
The extension phone setting 
might be disabled.
See
“Enabling an extension phone”
on page 38
for instructions about
changing this setting.
The telephone cord might not 
be securely connected.
Check that the telephone cord is 
securely connected between the 
phone and the product (or other 
device connected to the product). 
Press 1-2-3 in sequence, wait for 
three seconds, and then hang up.
Voice calls are not being 
received by the phone 
or answering machine 
connected to the line.
The phone cord might not be 
connected properly.
See
“Connecting the product to a
phone line” on page 5
to check the
installation. The product must be 
the first device connected to the 
phone line.
The answer mode or 
rings-to-answer settings 
might not be set properly.
See
“Setting the answer mode” on
page 12
or
“Setting
rings-to-answer” on page 14
to
determine which settings you need. 
The rings-to-answer must be set 
higher than for the answering 
machine.
The answering machine or 
phone might not be 
functioning.
Connect the phone or answering 
machine directly to the phone line 
and determine whether it works by 
itself.
Incoming fax calls are 
not being answered by 
the product.
The answer mode might be 
set to manual.
If the answer mode is set to 
manual, the product never answers 
calls. You have to answer the 
phone and start receiving the fax 
yourself. See 
“Setting the answer
mode” on page 12
for more
information.

Incoming fax calls are 
not being answered by 
the product (continued).
The rings-to-answer setting 
might not be set correctly.
Check the rings-to-answer setting 
for your configuration. See 
“Setting
rings-to-answer” on page 14
to
determine which setting you need.
The answer ring pattern 
feature might be turned on, 
but you do not have the 
service, or you do have the 
service and the feature is not 
set correctly.
Check the answer ring pattern 
feature to make sure it is set 
properly. See 
“Enabling answer
ring patterns” on page 15
.
The phone cord might not be 
connected properly, or the 
phone cord is not working.
See
“Connecting the product to a
phone line” on page 5
to check the
installation. Make sure you are 
using the phone cord that came 
with the product.
The product may not be able 
to hear incoming fax tones 
due to a voice message being 
played by the answering 
machine.
Re-record your answering machine 
message, leaving at least two 
seconds of silence at the beginning 
of the message.
There might be too many 
devices connected to the 
phone line.
Try removing the last device 
connected and determine whether 
the product works. If not, continue 
removing devices one at a time and 
retry after removing each one.
The phone line might not be 
working.
Do one of the following:
●
Turn up the volume on the 
product and press fax/send on 
the control panel. If you hear a 
dial tone, the phone line is 
working.
●
Disconnect the product from 
the phone jack and connect a 
phone. Try to make a phone 
call to make sure the phone 
line is working.

Incoming fax calls are 
not being answered by 
the product (continued).
A voice messaging service 
may be interfering with the 
product answering calls.
Do one of the following:
●
Discontinue the messaging 
service.
●
Get a phone line dedicated to 
fax calls.
●
Set the product to answer in 
manual mode. In manual 
mode, you must start the fax- 
receive process yourself.
●
Leave the product set to 
automatic mode and lower the 
rings-to-answer for the product 
to a number less than the 
rings-to-answer for the voice 
mail (see 
“Setting
rings-to-answer” on page 14
).
The product will answer all 
incoming calls.
The product might be out of 
paper and the memory is full.
Refill the paper input tray. The 
product will print all of the faxes it 
has saved in memory and will then 
resume answering fax calls.
Faxes are transmitting 
or being received very 
slowly.
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 product only sends the fax at 
the fastest modem speed the 
receiving fax machine can use. 
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 lower the 
resolution and resend the fax.
If you are sending, lower the 
resolution and resend the fax. See 
“Changing the default contrast and 
resolution for outgoing faxes” on 
page 18
to change the default
setting.

Faxes are transmitting 
or being received very 
slowly (continued).
If there is a poor phone line 
connection, the product and 
the receiving fax machine 
slow down the transmission 
to adjust for errors.
Hang up and resend the fax.
Have the phone company check 
the phone line.
Faxes are not printing 
or are printing 
incorrectly at the 
product. 
There is no media in the 
media input tray.
Load media. Any faxes received 
while the input tray is empty are 
stored in memory and will print 
once the tray has been refilled.
The receive to PC option 
might be selected, and faxes 
are being received by the 
computer.
Check to determine whether the 
computer is receiving faxes:
Click Start, point to Programs, 
point to HP LaserJet 3300, point to 
Tools, and click HP LaserJet 
Device Configuration.
Click the Fax tab, then the Receive 
tab.
Clear the Receive to PC check box 
if it is selected, and click OK. 
Faxes are printing on 
two pages instead of 
one.
The autoreduction setting 
may not be set correctly.
If you want faxes to be reduced to 
fit on one page, the autoreduction 
setting should be on. If the setting 
is off, faxes may print on multiple 
pages. See the autoreduction topic 
in the electronic user guide to 
adjust the setting.
Received faxes are too 
light or are printing only 
on half of the page.
The product ran out of toner 
while printing a fax.
The product stores up to 10 of the 
most recently printed faxes. As 
soon as possible, replace the print 
cartridge and see the instructions 
for reprinting a fax in the electronic 
user guide.
