FCC Regulations
This equipment has been tested and found
to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide
reasonable protection against harmful
interference in a residential installation. This
equipment generates, uses, and can radiate
radio frequency energy. If this equipment is
not installed and used in accordance with the
instructions, it may cause harmful
interference to radio communications.
However, there is no guarantee that
interference will not occur in a particular
installation. If this equipment does cause
harmful interference to radio or television
reception, which can be determined by
turning the equipment off and on, the user is
encouraged to try to correct the interference
by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase separation between equipment and
receiver.
Connect equipment to an outlet on a circuit
different from that to which the receiver is
located.
Consult your dealer or an experienced radio/
TV technician.
Any changes or modifications to the printer
that are not expressly approved by HP could
void the user's authority to operate this
equipment.
Use of a shielded interface cable is required
to comply with the Class B limits of Part 15 of
FCC rules.
This equipment complies with FCC rules,
Parts 15 and 68. On the back of this
equipment is a label that contains, among
other information, the FCC registration
number and ringer equivalence number
(REN) for this equipment. If requested, this
information must be provided to the
telephone company. The REN is used to
determine the quantity of devices which may
be connected to the telephone line.
Excessive RENs on the telephone line may
result in the devices not ringing in response
to an incoming call. In most, but not all, areas,
the sum of the RENs should not exceed five
(5.0). To be certain of the number of devices
that may be connected to the line, as
determined by the total RENs, contact the
telephone company to determine the
maximum REN for the calling area.
This equipment is designed to be connected
to the telephone network or premises wiring
using a compatible modular jack which is
Part 68 compliant. This equipment cannot be
used on telephone company-provided coin
service. Connection to Party Line Service is
subject to state tariffs. If this equipment
causes harm to the telephone network, the
telephone company will notify you in
advance that temporary discontinuance of
service may be required. If advance notice is
not practical, the telephone company will
notify the customer as soon as possible.
Also, you will be advised of your right to file
a complaint with the FCC if you believe it is
necessary. The telephone company may
make changes in its facilities, equipment,
operations, or procedures that could affect
the operation of the equipment. If this
happens, the telephone company will
provide advance notice in order for you to
make the necessary modifications in order to
maintain uninterrupted service. If trouble is
experienced with this equipment, please see
the numbers in the front of this manual for
repair and (or) warranty information. If the
trouble is causing harm to the telephone
network, the telephone company may
request you remove the equipment from the
network until the problem is resolved. The
following repairs can be done by the
customer: Replace any original equipment
that came with the device. This includes the
print cartridge, the supports for trays and
bins, the power cord, and the telephone cord.
It is recommended that the customer install
an ac surge arrestor in the ac outlet to which
this device is connected. This is to avoid
damage to the equipment caused by local
lightning strikes and other electrical surges.
See the electronic user guide for more
regulatory information.
This equipment uses the following USOC
jacks: RJ11C.
An FCC-compliant telephone cord and
modular plug is provided with this equipment.
