Fax Failure After Installation/Relocation
Phaser 6128MFP Service Manual
simultaneously accommodates analog (voice) and digital information on the
same line. Downstream data rates are offered from 512 Kbps to about 6
SDSL (Symmetric Digital Subscriber Line) – Runs over one pair of copper wires
with symmetrical upstream and downstream transmission speeds up to 3
Mbps, with a maximum range up to 3 km.
VDSL (Very high Bit Rate Digital Subscriber Line) – An xDSL technology that
provides faster data transmission over a single twisted pair of copper wires.
VDSL transmits data from 13 Mbps ~ 55 Mbps range over short distances,
usually between 1000 and 4500 feet.
If electronic equipment (television, computer, microwave, etc.) or devices equipped
with motors are located near a Fax, noise from the electronic equipment may
degrade the line condition.
Also, a telephone line, acting as an antenna, may absorb electric waves generated
from wireless or broadcasting equipment.
Because Fax data is audio data, the line quality affects the quality/stability of
image data as well as that of conversation.
The Fax has failed to send after installation. The following troubleshooting
procedure applies to this error.
Disconnect all devices other than the Fax machine.
Cycle printer power.
If the problem persists, follow the procedure below.
The conventional analog telephone line uses standard RJ-11 cable, which has two
conductors. However, the four-conductor cables commonly available are backward
compatible with RJ-11 and can be used with no problems. On the other hand, since
these four-conductor cables are also used for ISDN systems, the number of
elements is not the key for identification of the type of line/service.
