 
Connecting additional devices
Depending on the setup of your phone lines, you can connect additional 
devices to the phone line along with your HP LaserJet 3330.
As a general rule, no more than three or four devices should be 
connected to a single phone line. If too many devices are connected to a 
single phone line, one or more of the devices may not detect an 
incoming call. If this occurs, disconnect one or more of the devices.
Note
The HP LaserJet 3330 cannot replace a computer modem. It will not act 
as a data modem for sending and receiving e-mail, connecting to the 
Internet, or communicating with other computers.
Dedicated fax line
If you connected your HP LaserJet 3330 to a phone line that is used only 
for fax calls, you may want to connect the following devices:
●
Modem: You can connect a computer modem (external or internal) 
to the fax line if you want to use the fax line for e-mail or for access 
to the Internet, but you cannot send or receive faxes while using the 
line for these purposes.
●
Extra phone: You can connect an extra phone to the fax line if you 
want to make outgoing calls on the fax line.
You should not connect the following devices:
●
Answering machine or computer voicemail: If you use computer 
voicemail, you must connect a modem (external or internal) to your 
dedicated voice line. Then, use the dedicated voice line to connect 
to the Internet and receive voicemail.
Shared phone line
If you connected your HP LaserJet 3330 to a phone line that is shared 
between fax calls and voice calls, or if you have one phone line with two 
phone numbers and a ring pattern service, you may want to connect the 
following devices:
●
Modem: You can connect a computer modem (external or internal) 
to the shared line if you want to use the shared line for e-mail or for 
access to the Internet, but you cannot send or receive faxes while 
using the line for these purposes.
●
Phone: You can connect a phone to the shared line if you want to 
make or receive voice calls on the shared line.
●
Answering machine or computer voicemail: You should connect 
these devices to the same phone jack as the product to make sure 
the different devices do not interfere with one another.

Note
It is possible to connect devices to another phone jack for the same phone 
line (in another room, for example); however, the devices may interfere 
with faxing and with each other.
