1. Employing lead-free solder
The TEL/LIU PWB and Operation Panel PWB of this model employs lead-free solder.
This is indicated by the "LF" symbol printed on the PWB and in the service manual.
The suffix letter indicates the alloy type of the solder.
Example:
Indicates lead-free solder of tin, silver and copper.
2. Using lead-free solder
When repairing a PWB with the "LF" symbol, only lead-free solder should be used. (Using normal tin/lead alloy solder may
result in cold soldered joints and damage to printed patterns.)
As the melting point of lead-free solder is approximately 40°C higher than tin/lead alloy solder, it is recommended that a
dedicated bit is used, and that the iron temperature is adjusted accordingly.
3. Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer melting point (flow), to prevent damage to the
land of the PWB, extreme care should be taken not to leave the bit in contact with the PWB for an extended period of time.
Remove the bit as soon as a good flow is achieved.
The high content of tin in lead free solder will cause premature corrosion of the bit.
To reduce wear on the bit, reduce the temperature or turn off the iron when it is not required.
Leaving different types of solder on the bit will cause contamination of the different alloys, which will alter their
characteristics, making good soldering more difficult.
It will be necessary to clean and replace bits more often when using lead-free solder. To reduce bit wear, care should be
taken to clean the bit thoroughly after each use.

• With special sizes, only one sheet can be fed into the machine at a
time. Insert next page into feeder as current page is being scanned.
2. Paper Thickness & Weight
3. Document Types
• Normal paper
Documents handwritten in pencil (No. 2 lead or softer), fountain
pen, ball-point pen, or felt-tipped pen can be transmitted.
Documents of normal contrast duplicated by a copying machine
can also be transmitted.
• Diazo copy (blue print)
• Diazo copy documents of a normal contrast may be transmitted.
• Carbon copy
A carbon copy may be transmitted if its contrast is normal.
4. Cautions on Transmitting Documents
• Documents written in yellow, greenish yellow, or light blue ink can-
not be transmitted.
• Ink, glue, and correcting fluid on documents must be dry before the
documents can be transmitted.
• All clips, staples and pins must be removed from documents before
transmission.
• Patched (taped) documents should be copied first on a copier and
then the copies used for transmission.
• All documents should be fanned before insertion into the feeder to
prevent possible double feeds.

[4] Installation
1. Site selection
Take the following points into consideration when selecting a site for
this model.
ENVIRONMENT
• The machine must be installed on a level surface.
• Keep the machine away from air conditioners, heaters, direct sun-
light, and dust.
• Provide easy access to the front, back, and sides of the machine.
In particular, keep the area in front of the machine clear, or the orig-
inal document may jam as it comes out after scanning.
• The temperature should be between 41 - 95°F (5 - 35°C).
• The humidity should be between 25% and 85% (without conden-
sation).
ELECTRICITY
AC 120V, 60Hz, grounded (3-prong) AC outlet is required.
Caution!
• Connection to a power source other than that specified will cause
damage to the equipment and is not covered under the warranty.
• If your area experiences a high incidence of lightning or power
surges, we recommend that you install a surge protector for the
power and telephone lines. Surge protectors can be purchased at
most telephone specialty stores.
If the machine is moved from a cold to a warm place...
Condensation may form on the reading glass if machine is moved from
a cold to a warm place, this will prevent proper scanning of documents
for transmission. Turn on the power and wait approximately 2 hours
before using machine.
TELEPHONE JACK
A standard RJ11C single-line wall telephone jack must be located near
the machine. This is the telephone jack commonly used in most
homes and offices.
• Plugging the fax machine into a jack which is not RJ11C single-line
wall telephone jack may result in damage to the machine or your
telephone system. If you do not know what kind of jack you have, or
need to have one installed, contact the telephone company.
2. Loading the imaging film
Your fax uses a roll of imaging film to create printed text and images.
The print head in the fax applies heat to the imaging film to transfer ink
to the paper. Follow the steps below to load or replace the film.
• The initial starter roll of imaging film included with your fax can print
about 30 letter-size pages
• When replacing the film, use a roll of Sharp UX-5CR imaging film.
One roll can print about 150 letter-size pages.
1) Remove the paper from the paper tray and open the operation
panel (press ).
2) Remove the used film and empty spool.
3) Remove the two green gears from the spools.
DO NOT DISCARD THE TWO GREEN GEARS!
4) Remove the new roll of imaging film from its packaging.
• Cut the band that holds rolls together.
5) Insert the green gears.
Make sure the gears fit into the slots in the ends of the rolls.
Use only Sharp Genuine

8) Close the operation panel (press down on both sides to make sure
it clicks into place).
3. Connections
1) Connect the handset as shown and place it on the handset rest.
• The ends of the handset cord are identical, so they will go into
either jack.
• Make sure the handset cord goes into the jack marked with a
handset symbol on the side of the machine.
• Use the handset to make ordinary phone calls, or to transmit
and receive faxes manually.
2) Plug the power cord into a 120 V, 60 Hz, grounded AC (3-prong)
outlet.
Caution!
Do not plug the power cord into any other kind of outlet. This will
damage the machine and is not covered under the warranty.
• The machine does not have a power on/off switch, so the power
is turned on and off by simply plugging in or unplugging the
power cord.
3) Insert one end of the line cord into the jack on the back of the
machine marked TEL. LINE. Insert the other end into a standard
(RJ11C) single-line wall telephone jack.
Setting the dial mode: The fax machine is set for tone dialing. If you
are on a pulse dial line, you must set the fax machine for pulse dial-
ing. Press the keys on the operation panel as follows:

3.1. Soft switch mode
Used to change the soft switch settings.
The soft switch which is stored internally is set by using the keys.
The available soft switches are SW-A1 to SW-O6.
The content of soft switches is shown in page 2-5 to 2-18.
The contents are set to factory default settings.
3.2. ROM & RAM check
ROM executes the sum check, and RAM executes the matching test.
The result will be notified with the number of short sounds of the
buzzer as well as by printing the ROM & RAM check list.
Number of short sounds of buzzer:
0 →No error
1 →ROM error
2 →RAM error (4 Kbyte SRAM or 512 Kbyte DRAM)
3.3. Aging mode
If any document is present, copying will be executed sheet by sheet. If
no document is present, the check pattern will be printed sheet by
sheet. This operation will be executed at a rate of one sheet per 5 min-
utes, and will be ended at a total of 10 sheets.
3.4. Panel key test
This mode is used to check whether each key operates properly.
Press the key on the operation panel, and the key will be displayed on
the display. Therefore, press all keys. At this time, finally press the
STOP key.
When the STOP key is pressed, the keys which are not judged as
"pressed" will be printed on the result list.
• LED part of the contact image sensor (CIS) is kept on during the
term from when “START” of the panel test mode to end with the
STOP key.
3.5. Check pattern
This mode is used to check the state of the printing head. It is ended
with the following pattern printed on one printing sheet.
3.6. Signal send mode
This mode is used to send various signals to the circuit during FAX
communication. Every push of START key sends a signal in the follow-
ing sequence. Moreover, the signal sound is also output to the speaker
when the line monitor of the soft switch is on.
