1 Employing lead-free solder
The Power supply 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.
22
22
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 40ºC higher than tin/lead alloy solder, it is recommended that a
dedicated bit is used, and that the iron temperature is adjusted accordingly.
33
33
3 Soldering
As the melting point of lead-free solder (Sn-Ag-Cu) is higher and has poorer wettability (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.

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. 50 sheets (14 lbs - 20 lbs)
Special size: single sheet only (manual feed)
NOTES: •If you need to send or copy more 50 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.

1. Site selection
Take the following points intoconsideration when selecting a sitefor 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 50°and 86°F (10°and 30°C).
•The humidity should be between 30% 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.
•Ifyourareaexperiences a high incidence of lightning or power surges,
we recommend that you install a surge protector for the power and
telephonelines. Surge protectors canbepurchasedatmost telephone
specialty stores.
TELEPHONE JACK
A standard RC11C telephone jack must be located near the machine.
This is the telephone jack commonly used in most homes and offices.
•Pluggingthe fax machine into ajack which is not anRC11C jackmay
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.
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 fog up,preventingproper scanning of documents
for transmission. To remove the fog, turn on the power and wait approxi-
mately 2 hours before using the machine.
2. Assembly and connections
1 Connecting the power cord
Connect the female end of the power cord to the fax machine as
shown. Insert the male end into a 120 V, 60 Hz, grounded (3-prong)
AC outlet.
Important!: The fax machine requires its own dedicated power outlet.
The power outlet must not be shared with any other devices. In particu-
lar, do not use an extension cord to connect multiple devices to the
outlet.
Note: If your area experiences a high incidence of lightning or power
surges, we recommend that you install surge protectors for the power
and telephone lines. Surge protectors can be purchased at most tel-
ephone specialty stores.

•It is shifted to set the last soft switch with the [ ] key.
•It is shifted to set another soft switch by inputting two digits as the
switch number. (When 2 digits are completely input.)
•Output of the soft switch list is started.
6 Inhibition of data change
(This is also applicable for the optional setting.)
In the following case, it is inhibited to change the data with the key
error buzzer.
•Switching ON/OFF of ECM during the use of image memory.
•OFF to ON of telephone billing function which is using the image
memory is used (Note: In the existing set, the telephone billing
codefunction is specified from OFFtoON when the timer system
communication (including the batch communication) is set.)
Here,thememory is usable when the telephone billing code func-
tion is on. It can be set from ON to OFF while the memory is
used. However, if setting is practically changed even once, it can
not be returned from OFF to ON.

This is a mode to check that the flash memory acts normally. The flash
memories shown in the following table are checked.
•NAND-Flash (optional) is valid only when the optional memory is
mounted.
1 The NOR flash memory test is executed.
2 The concerned alarm buzzer sounds only when the error occurs.
3 The NAND flash memory test is executed.
4 The concerned alarm buzzer sounds only when the error occurs.
5 The result is printed.
NOTE:
•During operation of this diagnosis, dual operation is not possible at all.
•Ifthisisexcessivelyrepeated,itwill shorten the life of the flash memory.
M) All FAX/TEL. entry mode
This is a function to copy the FAX and TEL numbers registered in the
one-touch dialing (RAPID) key [01] to the all one-touch dialing (RAPID)
key and the all abbreviated number (SPEED DIAL) to simplify the FAX
and TEL number registration at the time of aging.
1 Copy the Fax and Tel numbers (including agency) registered in the
one-touch dialing (RAPID) key [01] to all one-touch dialing (RAPID)
key.
2 Copy the FAX and TEL numbers registered in the one-touch dialing
(RAPID) key [01] to the all abbreviated number (SPEED DIAL).
3 In case the chain dial is not set in the one-touch dialing (RAPID) key
[01], register the one-touch dialing (dialing) keys [02] –[59] and all
abbreviated number (SPEED DIAL) to the group number [01].
In case that the chain dial is set, do not create a group, but cancel
only the chain dial setting of the one-touch dialing (RAPID) key [01].
(All except for the one-touch dialing (RAPID) key [01], chain dial is
kept set.)
4 Enter all registered one-touch send (RAPID) keys and speed dial
numbers (SPEED DIAL) on the personal books [01] - [10].
Following this, set the password registration and the password
setting to ON, and set the TTI setting to OFF.
The call-receiver names and book names are specified as follows:
(The letters after 16th letter of the call-receiver’s name registered in the
one-touch dialing [01] are cut off.)
NOTE: Before entering this mode, FAX and TEL numbers must be reg-
istered in the one-touch dialing (RAPID) key [01].
(In case that they are not registered, or a program or a group is
registered, it is not executed.)
N) Dept. passcode
The department passcode list is printed.
O) Conf. passcode
The confidential passcode list is printed.
Differing from printing of one box alone soon after registration, the con-
fidential passcodes of all boxes are printed.
P) Signal send mode 2
The signals concerned with V.34 & V.8 are checked.
After this mode is activated, press the START key, and the signals will
be sent in the following sequence.
It can be used to check the modem.
[ 1] No signal
[ 2] 33600BPS (V. 34)

Q) Memory set mode
The set and dump list of the memory content is output.
•The address (8 digits (P) generally including the bank information is
input, and the data of 2 digits is continuously input.
Inputting is done in the hexadecimal mode. The ten-key is used for 0
through 9, and the alphabetic keys A (RAPID 01 through 06) are
used forA through F.
•During data inputting, the address can be moved forward and back-
ward one byte by one byte with " " and "#". (The address prior to the
address 0 is looped as the maximum address.)
•The Validity of the address is not checked.Accordingly, writing/ read-
ing operations are possible in the address of the memory not as-
signed, the address of ROM and so on.
(However, as practical, writing is not done, and the data content runs
short each reading.)
Though writing is possible in the flash memory, a little time is re-
quired.
It is also necessary to take care that the life of the flash memory is
excessively shortened if much data is written in the flash memory.
Since it may run away depending the written content, take minute
care for the writing address.
•When the REPORT key is input, the memory dump list is produced
from the displayed address (here, it is limited at the 16-byte bound-
ary address (address with end 0) which does not exceed the speci-
fied address and is just in front.). The dump list is output to a maxi-
mum of 99 pages. If any data of one page can be repeatedly devel-
oped and printed, the list is sufficient. But it is not desired that the
content of plural pages are developed in the memory once and are
then printed. If the STOP key is pressed, it will pass to the diagnosis
after the page which is now being printed is completed printed.
If the address exceeds the maximum address, it will return to the
address 0 and printing will be continued.
