General Troubleshooting
Noise
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.
