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 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.
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: • When you need to send or copy more pages than the
feeder 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
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.

• Readable length
This is the length of the document sent minus 4 mm from the top and

7. Use of Document Carrier Sheet
A document carrier sheet must be used for the following documents.
• Those with tears.
• Those smaller than size 148 mm (W) × 128 mm (L).
• Carbon-backed documents
Make print straight
across paper
E.G.
Place the document
carrier in the document
feeder with the clear film
side down
Direction of insertion
NOTE: To transmit a carbon-backed document, insert a white
sheet of paper between the carbon back of the document
and the document carrier.
• Those containing an easily separable writing substance (e.g., trac-
ing paper written on with a soft, heavy lead pencil).
NOTES: • When using the document carrier, carefully read the in-
structions written on the back.
• If the document carrier is dirty, clean it with a soft, moist
cloth, and then dry it before using for transmission.
• Do not place more than one document in the carrier at a
time.
• The thickness of document which can be held with the carrier
sheet is up to 20 lb.
TELEPHONE JACK
A standard single-line 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 single-line
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, 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. To remove the fog, turn on the power
and wait approximately 2 hours before using the machine.
2. Installing the printer cartridges (Toner
cartridge: FO-45DC/Drum cartridge: FO-45DR)
1
Press the button on the side of the printer compartment, and open
the printer cover.
• Caution! The ribs on the bottom of the inside of the printer
cover become very hot during printing. Be careful not to touch
them.
• If you are installing the cartridges for the first time, go to Step 4.
[4] Installation
1. Site selection
Take 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 41° and 95°F (10° and 35°C).
• The humidity should be between 30% and 85% (without condensa-
tion).
ELECTRICITY
AC 230 V, 50 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 specialty stores.
2
If you are replacing the cartridges, grasp the handle on the toner
cartridge, and pull the toner cartridge out of the compartment.
• If you are only replacing the drum cartridge, place the toner
cartridge on a piece of paper on a horizontal surface.

In the soft switch mode, press the REPORT key, and the soft switch list
will be output.
If the recording paper runs out or is clogged, the key error buzzer will
sound with the process not received.
5
Storage of data
In the following case, the data of the soft switches set will be stored.
• It is shifted to set the next soft switch by pressing the START switch.
• It is shifted to set the next soft switch with the [#] key.
• 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.
• OFF to ON of telephone billing function which is using the image
memory is used (Note: In the existing set, the telephone billing code
function is specified from OFF to ON when the timer system communication (including the batch communication) is set.)
Here, the memory is usable when the telephone billing code function 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.
• When the PC interface board is not mounted, [Switch of OFF → ON
of the item of "PC interface function" and of FAX → PC of the item
of "automatic receiving in the PC interface mode]
(Note: This supports not only the operation protect of the optional setting and soft switch mode but also an example of the
automatic compensation of soft switch to OFF/FAX when the
power is turned on even if the PC PWB is removed when the
optional setting and soft switch mode are set at ON/PC.)
(Though they are not provided, the existing model can operate
without setting of the soft switch when it is not installed.)
• OFF to ON of multi TTI function and telephone billing code function
when the department control function is OFF.
• OFF to ON of department control function during use of image
memory.
(Note: In the existing set, the department control function is set from
OFF to ON when the timer communication (including the batch
sending) or the memory hold is set.)
• ON to OFF of continuous serial polling function when the continuous
serial polling is started.
(Note: In the existing set, "ON to OFF of the continuous serial
polling function when the continuous serial polling is registered" has
been applied, but the conditions are now moderated. However, reg-
istration is impossible to the program of the new continuous serial
polling when the continuous serial polling function is OFF.)
• In addition, change of all soft switches during communication
7
Linked change of data (This is the same even in the optional setting.)
• When the department control function is off, the multi TTI function
and telephone billing code function are turned off.
2) Print area
According to the size of the specified sheet, the effective printing area is
printed.
3) ROM & RAM check
The sum value of ROM, the work and the back-up RAM are checked.
The RS232C interface is also checked. If any error occurs, the buzzer will
inform it. (Refer to the following table). Finally, the result will be printed.
This diagnosis does not check the flash memory. The flash memory is
checked with the flash memory test.
Number of buzzer sounds Device checked Remarks
1 time <Short sound> ROM1 Main
2 times <Short sounds> ROM2 Main
3 times <Short sounds> Integrated ROM/RAM Main
4 times <Short sounds> D-RAM Main
5 times <Short sounds> S-RAM Main
*6 times <Short sounds> S-RAM (on the optional memory) Main
* As practical, it is judged that the optional memory is not installed if any
error occurs. Therefore, it does sometimes not sound.
For the short and long sounds, one pattern is as follows.
Main system: 0.25 seconds ON/0.25 seconds OFF
Sub system: 1.00 second ON/0.25 seconds OFF
The execution state of checking is as follows. Moreover, the list of the
check result is output after checking is ended.

pages and the existing mode can not be changed.
• While the sending paper is read, the image quality key can be
input. STD/FINE/S-FINE modes are usable. However, the
same operation of FINE will be selected if the intermediate tone
is set.
• The image quality, the length of the sending page read, the
page distance to the next sending paper and the total of the
sending papers read are shown on the display.
• When the stop key is pressed or 100 sending papers are read,
the content shown on the display will be totally output as the list
after the remaining sending papers are discharged.
5) Aging mode

ROM&RAM check process. The write/read test is taken every block to
print the result.
When an error occurs, the following error buzzer will sound.
Number of buzzer sounds Check device
7 times <Short sounds> Page memory
8 times <Short sounds> Flash memory
9 times <Short sounds> Flash memory (optional)
During operation of this diagnosis, dual operation is not possible at
all.
If this is excessively repeated, it will shorten the life of the flash
memory.
13) All FAX/TEL. entry mode
Before entry into the diagnosis, the reference destination number is
first written into the Rapid key number 01 in the FAX number registration mode.
1
The diagnosis mode is activated. If any number is not registered in
the Rapid key number 01 or any program or group is registered,
the diagnosis will be passed without any execution.
2
The FAX/TEL No. (including the substitutive one) of the Rapid key
number 01 is copied into the Rapid key numbers 02 thru 48.
18) 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 thru 9, and the alphabetic keys A (RAPID01 thru 06) are used for
A thru F.
• During data inputting, the address can be moved forward and
backward 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, writ-
ing/reading operations are possible in the address of the memory
not assigned, 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
required.
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 boundary address (address with end 0) which does not exceed the specified address and is just in front.). The dump list is output to a
maximum of 99 pages. If any data of one page can be repeatedly
developed 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.

19) Motor aging
• Whether a document is present or not, the motor in the sending
system is kept in rotation until the STOP key is pressed.
• The image quality selection key can be input during stop alone to
set the rotation speed for the image quality.
(Here, the speed for FINE is selected when the intermediate tone
is specified.)
• The image quality for default at the start of execution is STD
regardless of the image quality selection priority of the main body.
• For rotation, the key "1" selects the 1-2 phase excitation, "2"
selects the 2-phase excitation and "3" selects the micro step. It can
not be changed during rotation. The 1-2 phase excitation is set as
default.
20) Stamp aging
• It is impossible if any document is not set up.
• The document is fed at the 10 mm intervals, and is continuously
stamped.
• The total number of stamps from entry of the mode is displayed on
the screen.
• The ordinary operation aging which stamps a finish every docu-
ment is executed in the ordinary copying mode.
21) Scanner set mode
• The reading width and motor drive conditions are set.
<Reading width>
1. Top margin
2. Bottom margin
3. Left adjustment (The left position alone is specified.)
Specify the above values.
• Select the above items 1, 2 and 3 with the [ ] and [#] keys, and
set the values with the [←] and [→] keys. The values can be set in
the range of +3.0 mm to -3.0 mm at the 0.1 mm intervals. While
the [←] and [→] key is continuously pressed one second or more,
the setting value is automatically increased/decreased (in the
range between the upper and lower limits).
• Input the quality selection key, and the value will be respectively
set corresponding to the selected image quality. Here, the intermediate tone is the same as for the setting value of FINE.
• ±0.0 mm is default for all.
<Drive conditions of motor>
4. Motor
5. Phase
6. Slow-up
7. Slow-down
Specify the above values.
• Select the above items 4 thru 7 with the [ ] and [#] keys, and
select the setting value with the ten-key.

22) Dial test mode
The mode is used to inspect whether dialing is accurate in two kinds
of dial modes . All data which can be dialed in this mode are
automatically called up in both PB mode and DP mode.
When this mode is activated, the following operations will be automatically executed . Whether the dialed content is right or not is judged
with the external instrument which is connected to the line cable.
1
After shift to the FAX diagnosis mode, press RAPID 24.
(Also switch the display with the [ ] and [#] keys.)
2
Press the START key.
3
Turn on CML, and dial the following in the PB mode.
1, 2, 3, 4, 5, 6, 7, 8, 9, , 0, #
4
Turn off CML 500 mS alone.
5
Dial the following in the DP mode.
1, 5, 9, 0
6
After dialing, turn off CML.
This mode uses the ordinary auto dial. (Accordingly, the signal sending time and minimum pause are all the same as ordinary.
The measurement result in this mode is completely all the same as in
the ordinary dial mode.
Moreover, the same process as above is also done in the dial test
mode which is executed in the product check mode.
23) Copy diag mode
In order to shorten the process time during production, this mode is
used to automatically switch the copy mode. Three menus are provided.
1. 1Set up two documents. (In case of two documents or more,
there is no problem.
2Press the START key.
3Copy 1st document in the fine mode/density AUTO. (One
sheet is printed in the ordinary copy mode.)
4Copy 2nd (subsequential) document in the intermediate
tone mode/density DARK. (In the ordinary copying mode,
one sheet is printed when the RESOLUTION key is pressed
three times.)
When copy test is tried during production or is checked in two modes
(fine and intermediate tones), this mode is provided to reduce the
troublesome work which makes the operator stand aside to change
the mode. Accordingly, the fine and intermediate tones are merely
switched, and the mode is not switched to another mode. (Input of the
image quality/density key is invalid.)
2. Try the copy in the mode fixed at COPY REDUCE 95% and
fine mode/density AUTO. At this time, don’t change the soft
key of COPY REDUCE. (Input of the image quality/density key
is invalid.
3. Continuously try the above items 1 and 2.
