[4] Installation
1. Site selection
Take the following points intoconsideration whenselecting 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 original
document may jam as it comes out after scanning.
•The temperature should be between 5°and 35°C.
•The humidity should be between 30% and 85% (without conden-
sation).
ELECTRICITY
AC 220-230V, 50Hz, earthed (2-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.
•Ifyourarea experiences ahighincidenceof lightning orpowersurges,
we recommend that you install a surge protector for the power and
telephonelines.Surgeprotectors can be purchasedatmosttelephone
specialty stores.
If the machine is moved from a cold to a warm place...
If the machine is moved from a cold to a warm place, it is possible that
thereading glassmay fog up, preventing properscanning ofdocuments
for transmission. To remove the fog, turn on the power and wait approxi-
mately 2 hours before using the machine.
TELEPHONE JACK
A standard 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 an jack may result
in damage to the machine or your telephone system. If you do not
know what kind of jack you have, or needed to have one installed,
contact the telephone company.
2. Loading the imaging film (UX-3CR)
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 30A4 pages.
•When replacing the film, use a roll of Sharp UX-3CR imaging film.
One roll can print about 95A4 pages.
Note: If there is paper in the paper tray, pull the paper release plate
forward and remove the paper before loading the imaging film.

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-M2.
The content of soft switches is shown in page 2-5 to 2-16.
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 (32Kbyte)
3. 3. Aging mode
Ifany documentisfirst present,copyingwill beexecuted sheet bysheet.
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 5min-
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 or not.
Press the key on the operation panel, and the key will be displayed on
