General Troubleshooting
One Page Fax Printed on Multiple Pages
A single page fax will print on multiple pages if the original document paper size is
too big.
You can use the Scale to Fit function to select whether documents longer than the
current paper size are printed reduced, split, or discarded. In the Fax menu, select
Fax Default Setup > Receive Option > Scale to Fit and then select one of the
following options.
On: The document is printed at a reduced size.
Off: The document is printed at full size and split onto multiple pages
Crop: The document is printed, but any part that does not fit within the page is
erased.
Other Fax Problems
Branch Connection (Parallel Connection)
During Fax reception, if the handset of another telephone on a branch connection
is lifted, the received image can be corrupted or a transmission error may occur.
Branch connection may also interfere with Caller ID, Call Waiting, or the receiving
operation of the connected telephones.
Call Waiting
If a call comes in during Fax sending/reception, the image may be corrupted.
Digital Subscriber Line
Digital Subscriber Line (DSL) is a high-speed digital transmission method using
existing telephone lines. Because the line is used for both voice and data
transmission, various problems may occur, such as noise during spoken
conversation, low sound volume, and mis-dialing. Replacing the splitter may
improve the situation.
The Digital Subscriber Line cannot be directly connected to a fax machine; the line
must be connected via a filter.
There are several types of DSL:
• ADSL (Asymmetric Digital Subscriber Line) – Transmits digital information at a
high-speed bandwidth on phone lines. ADSL provides continuously available
connection with differing upstream and downstream transmission speeds and
simultaneously accommodates analog (voice) and digital information on the
same line. Downstream data rates are offered from 512 Kbps to about
6Mbps.
• 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 over short distances, usually
between 1000 and 4500 feet.
