Laser Output Power : 0.3 mW ±0.05mW
CAUTION
This laser facsimile is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH or IEC60825-1 standard.
This means that this machine does not produce a hazardous laser radiation. The use of controls, adjustments or performance of
procedures other than those specified herein may result in hazardous radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eyes retina, there is
danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not an individual part.
2) Do not look into the machine with the main switch turned on after removing the toner/developer unit and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing
the optical system.
4) The cover of Laser Printer Unit contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

[3] Transmittable documents
1. Document Sizes
* 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 (blueprint)
Diazo copy documents of a normal contrast may be transmitted.
• Carbon copy
A carbon copy may be transmitted if its contrast is normal.
Normal size width 148 – 216 mm
length 128 – 279 mm
4. Cautions on Transmitting Documents
• Documents written in yellow, greenish yellow, or light blue ink cannot
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.
5. Automatic Document Feeder Capacity
Number of pages that can be placed into the feeder at anytime is as
follows:
Letter size: max. 20 sheets
Legal size: max. 5 sheets
Special size: single sheet only (manual feed)
NOTES: •If you need to send or copy more 20 pages, place the ad-
ditional pages and carefully in the feeder just before the
last page is scanned. Do not try to force them in, as this
may cause double-feeding or jamming.
•If your document consists of several large or thick pages
which must be loaded one at a time, insert each page into
the feeder as the previous page is being scanned. Insert
gently to prevent doublefeeding.
6. Readable Width & Length
The readable width and length of a document are slightly smaller than
the actual document size.
Note that characters or graphics outside the effective document scan-
ning range will not be read.

[4] Installation
1. Site selection
Take the following points into consideration when selecting a site forthis
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 10°and 30°C (50°and 86°F).
•The humidity should be between 20% and 85% (without condensa-
tion).
ELECTRICITY
AC 120 V, 60 Hz, 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.
•Ifyourareaexperiencesahighincidenceoflightningorpowersurges,
we recommend that you install a surge protector for the power and
telephonelines.Surgeprotectorscanbepurchasedat most telephone
specialty stores
TELEPHONE SOCKET
Astandard RJ11C telephone socket must be located near the machine.
This is the telephone socket commonly used in most homes and offices.
•Plugging the fax machine into a socket which is not an RJ11C socket
may result in damage to the machine or your telephone system. If
you do not know what kind of socket you have, or need to have one
installed, contact the telephone company.
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 glass may fogup, preventing proper scanningof documents
for transmission. To remove the fog, turn on the power and wait approxi-
mately 2 hours before using the machine.
The laser printer in your fax machine uses a toner cartridge and a
drum cartridge. The drum cartridge comes pre-installed, and the
toner cartridge must be installed.
• The drum cartridge can print approximately 20,000 letter-size
pages. When replacing the drum cartridge, use a Sharp
FO-29DR drum cartridge.
Follow the steps below to install the toner cartridge and prepare the
drum cartridge.
1 Grasp the print compartment cover at both sides as shown, and
pull up to open the cover.
•Caution! The fusing unit inside the print compartment becomes
very hot during operation. Do not touch the inside of the
compartment or the paper guide on the underside of the print
compartment cover.
2
The drum cartridge has been installed at the factory. Remove the
protective board from above the drum cartridge, and then grasp the
tabs on the drum cartridge handle with both hands and gently pull
the cartridge out of the machine. Remove the sheet of protective
paper from the cartridge and then insert it back into the machine.
• When removing the drum cartridge, be careful not the tear the
paper or leave any pieces of paper in the machine.
The starter toner cartridge
included with your fax can
print approximately 1,800
letter-size pages at 4%
page coverage.
When replacing the toner
cartridge, use a Sharp
FO-29ND toner cartridge can

2 Connecting the power cord
Plug the power cord into a 120 V, 60 Hz, grounded AC (3-prong)
outlet.
• Do not plug the power cord into any other kind of outlet. This will
damage the machine and is not covered under the warranty.
Insert one end of the line cord into the socket on the side of the
machine marked TEL. LINE. Insert the other end into a wall
telephone socket.
3 Connecting the telephone line cord
1 Connecting the handset
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 socket.
Use the handset to make ordinary phone calls, or to transmit and
receive faxes manually.
Make sure the handset
cord goes into the jack
marked with a handset
symbol on the side of
the machine!
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.
Make sure that the line
cord is inserted into
the TEL LINE jack. Do
not insert it into the
TEL. SET jack!
The fax machine is set for tone dialing. If you are on a pulse dial line,
you must set the fax machine for pulse dialing. Press the keys on the

5. Loading Printing Paper
1 Remove the paper tray cover.
2 If you are going to load legal size paper, flip up the paper tray
extension and extend the paper tray cover.
3 Fan the paper, and then tap the edge against a flat surface to
even the stack.
4 Pull the paper release lever toward you.
You can load up letter, A4 or legal paper in the paper tray.
• Up to 200 sheets of 20 lb. (70 g/m
2
) paper can be loaded.
• Up to 180 sheets of 21.5 lb. (80 g/m
2
) paper can be loaded.
Caution!
Do not use the blank side of paper that has already been printed on.
5 Insert the stack of paper firmly into the tray, print side up.
• Make sure that the stack is not higher than the marked line.
Loading too much paper may cause paper jams and misfeeds.
• If paper remains in the tray, take it out and combine it into a
single stack with the new paper before adding the new paper.
Important:
Be sure to load the paper so that printing takes place on the
print side of the paper. Printing on the reverse side may result in
poor print quality.
