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
Normal size width 148 –210 mm
length 140 –297 mm
5. Automatic Document Feeder Capacity
Number of pages that can be placed into the feeder at anytime is as
follows:
Normal size: max. ADF 5 sheets
Special size: single sheet only (manual feed)
NOTES: •Whenyouneed to sendorcopymorepages than thefeeder
limit, place additional pages in feeder when last page in
feeder is being scanned.
•Place additional pages carefully and gently in feeder.
If force is used, double-feeding or a document jam may
result.
6. Readable Width & Length

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
•Documentswrittenin yellow,greenishyellow, orlightblueink 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 be-
fore 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.

2. Connections
1. Connecting the handset
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 socket.
[4] Installation
1. Site selection
Take the following points into considerationwhen 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 5°and 35°C.
•The humidity should be between 30% and 85% (without conden-
sation).
ELECTRICITY
220-240 V, 50/60 Hz, earthed AC (2-prong) outlet.
Caution!
•Connection to a power source other than that specified will cause
damage to the equipment and is not covered under the warranty.
•Ifyourareaexperiences a high incidence oflightningorpowersurges,
we recommend that you install a surge protector for the power and
telephonelines.Surge protectorscan bepurchasedat mosttelephone
specialty stores.
If the machine is moved from a cold to a warm place...
Condensation may from 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 be-
fore using 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 need to have one installed, con-
tact the telephone company.
Make sure the handset cord
goes into the socket marked
withahandset symbol on the
side of the machine!
Use the handset to make ordinary
phone calls, or to transmit and receive
faxesmanually.
