Connecting additional devices Note Note Depending on how the phone lines are set up, additional devices can be connected to the phone line along with the HP LaserJet 3380 all-in-one. In general, no more than three 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 might not detect an incoming call. If this occurs, disconnect one or more of the devices. This product cannot replace a computer modem. It cannot act as a modem for sending and receiving e-mail, for connecting to the Internet, or for communicating with other computers. Dedicated fax line If the product is connected to a phone line that is used only for fax calls, the following devices can be connected: ● Caller ID box ● Modem-An internal or external computer modem can be connected to the fax line if the fax line is to be used for e-mail or access to the Internet. However, faxes might not be sent or received while the line is being used for these purposes. ● Extra phone-An extra phone line can be connected to the fax line if the fax is to be used for making outgoing calls. Do not connect an answering machine or computer voicemail system to the fax line. If the customer uses computer voicemail, connect the external or internal modem to the dedicated phone line. Then, use the dedicated voice line to connect to the Internet and receive voicemail. Shared phone line If the product is connected to a phone line that is shared between fax calls and voice calls, or if the phone line has two phone numbers assigned and uses a ring-pattern service, the following devices can be connected: ● Caller ID box ● Modem-An internal or external computer modem can be connected to the fax line if the fax line is to be used for e-mail or access to the Internet. However, faxes might not be sent or received while the line is being used for these purposes. ● Phone-Connect a phone to the shared phone line to make or answer voice calls on the shared line. ● Answering machine or computer voicemail system-Connect these devices to the same phone jack that the product uses in order to make sure that the different devices do not interfere with one another. It is possible to connect devices to another phone jack for the same phone line (for example, in another room). However, the devices might interfere with faxing and with each other. To connect additional devices Connect additional devices in the order that is described in the following steps. The output port for each device is connected to the input port of the next device, which forms a "chain." Skip the steps for devices that the customer is not using, and continue to the next device.
