HP laserjet 3390, 3392 all-in-one サービスマニュアル
NOTE
Hewlett-Packard does not recommend using a parallel splitter (T-splitter) with
the all-in-one because it might degrade the quality of the telephone signal. If a second
device must be attached to the telephone line in addition to the all-in-one, plug the
second device into the telephone port on the all-in-one (the port on the back that is
marked with a telephone icon).

●
Is a surge-protection device installed?
●
A surge-protection device might be installed between the telephone jack and the all-in-one to
protect the all-in-one from electrical power that passes through the telephone lines. These
devices might cause some fax communication problems by degrading the quality of the
telephone signal. If you are having problems sending or receiving faxes, connect the device
directly to the telephone jack to determine if the problem is in the surge-protection device.

●
Is a telephone company voice-message service being used?
●
If the messaging service rings-to-answer setting is lower than the all-in-one rings-to-answer
setting, the messaging service answers the call and the all-in-one will not detect incoming
faxes. If the all-in-one rings-to-answer setting is lower than that of the messaging service, the
all-in-one answers all calls and no calls will ever be sent to the messaging service. The only
voice-messaging system that can be used with the all-in-one is a standard telephone-
answering machine.

●
Is a standard telephone-answering machine installed?
●
An answering machine must be connected to the port that is labeled with the telephone icon
(or it can be shared on the same telephone-line extension). Set the all-in-one rings-to-answer
setting for at least one ring more than the number of rings that prompts the answering machine
to answer a incoming call. For example, if the answering machine is set to answer calls after
three rings, set the all-in-one rings-to-answer setting to four rings.

NOTE
If an answering machine is connected to the same telephone line but is connected
to a different jack (for example, in another room), it might interfere with the all-in-one to fax
reception.
