HP LaserJet 3055 - Manual (Page 129)

Connecting additional devices
Depending on the setup of your telephone lines, you can connect additional devices to the telephone
line along with the HP LaserJet all-in-one.
As a general rule, no more than three devices should be connected to a single telephone line. If too
many devices are connected to a single telephone line, one or more of the devices might not detect
an incoming call. If this occurs, disconnect one or more of the devices.
NOTE The HP LaserJet all-in-one cannot replace a computer modem. It cannot act as a
data modem for sending and receiving e-mail, connecting to the Internet, or communicating
with other computers.
Using a dedicated fax line
If you connect the HP LaserJet all-in-one to a telephone line that is used only for fax calls, you might
want to connect the following devices:
● Caller-ID box
● 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 telephone: You can connect an extra telephone 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.
Using a shared telephone line
If you connected the all-in-one to a telephone line that is shared between fax calls and voice calls, or
if you have one telephone line that has two telephone numbers and a ring-pattern service, you might
want to connect the following devices:
● Caller-ID box
● 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.
● Extra telephone: You can connect a telephone to the shared line if you want to make or
answer voice calls on the shared line.
● Answering machine or computer voicemail: You should connect these devices to the same
telephone jack as the all-in-one to make sure that the different devices do not interfere with one
another.
NOTE It is possible to connect devices to another telephone jack for the same telephone line
(in another room, for example). However, the devices could interfere with faxing and with each
other.
