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:

Normal size: max. 20 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 scan­ning range will not be read.

• Readable width

208 mm max.

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.

[4] Installation

1. Site selection

T ake 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 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.

• 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
speciality stores

2. Installing the toner cartridges

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 starter toner cartridge
included with your fax can
print approximately 1,875
letter-size pages st 4%
page coverage

• The drum cartridge can print approximately 20,000 letter-size
pages. When replacing the drum cartridge, use a Sharp
UX-400DR 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.

When replacing the toner
cartridge, use a Sharp
UX-400ND toner cartridge.
One cartridge can print about
3,750 letter-size pages.

TELEPHONE SOCKET

A standard 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 RJ1 1C 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
the reading glass may fog up, preventing proper scanning of documents
for transmission. T o remove the fog, turn on the power and wait approxi­mately 2 hours before using the machine.

2

The drum cartridge has been installed at the factory. Gently pull

the paper tab to remove the black sheet of protective paper from

• 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 th
print side of the paper. Printing on the reverse side may result in
poor print quality.

5. Loading Printing Paper

You can load up to 200 sheets of letter, A4 or legal paper (max. 20
lbs.) in the paper tray.

Caution!

Do not use the blank side of paper that has already been printed on.

If you are going to load legal size paper, pull out the paper tray
extension.

Fan the paper, and then tap the edge against a flat surface to
even the stack.



Make sure the stack of paper is aligned against the right pape

quide, and then gently move the left paper guide to the 8 1/2 posi­tion for letter or legal paper, or the A4 position for A4 paper.



Push the paper release lever back down.

• Note: If the paper does not feed correctly, remove the entir
stack from the tray and repeat the loading procedure from the
beginning.

Pull the paper release lever toward you.
