3. Diagnostic items description
3. 1. Soft switch mode
Used to change the soft switch settings.
The soft switch which is stored internally is set by using the keys.
The available soft switches are SW-A1 to SW-N3.
The content of soft switches is shown in page 2-5 to 2-19.
The contents are set to factory default settings.
3. 2. ROM & RAM check
ROM executes the sum check, and RAM executes the matching test.
The result will be notified with the number of short sounds of the buzzer
as well as by printing the ROM & RAM check list.
Number of short sounds of buzzer 0 →No error
1 → ROM error
2 → RAM error (4 Kbyte SRAM or
512 Kbyte DRAM)
3. 3. Aging mode
If any document is present, copying will be executed sheet by sheet. If
no document is present,the checkpattern willbe printed sheetby sheet.
This operation will be executed at a rate of one sheet per 5minutes, and
will be ended at a total of 10 sheets.
3. 4. Panel key test
This mode is used to check whether each key operates properly. Press
the key on the operation panel, and the key will be displayed on the
display. Therefore, press all keys. At this time, finally press the STOP
key.
When the STOP key is pressed, the keys which are not judged as
"pressed" will be printed on the result list.
•LED part of the contact image sensor (CIS) is kept on during the term
fromwhen "START"ofthe panel test modeto end with the STOPkey.
3. 5. Check pattern
This mode is used to check the state of the printing head. It is ended
with the following pattern printed on one printing sheet.
3. 6. Signal send mode
This mode is used to send various signals to the circuit during FAX com-
munication. Every push of START key sends a signal in the following
sequence.Moreover, the signal sound is also outputtothespeaker when
the line monitor of the soft switch is on.

3. 7. Memory clear
This mode is used to clear the backup memory and reset to the default
settings.
3. 8. Shading mode
The mode is used for the shading compensation. For reading, set up the
special original paper.
The compensation memorizes the reference data of white and black for
reading.
Moreover, the memorized data is not erased even if memory clear mode
is executed.
3. 9. All black print
This mode is used to check the state of the printing head and to inten-
tionally overheat it. Whole dots are printed over the interval of 2 m. If it is
overheatedor the printing sheetis jammed, press STOPkey fortheend.
3. 10. Auto feeder mode
In this mode, a document is inserted and discharged to check the auto
feed function.
After this mode is started, set a document, and the document feed will
be automatically tested.
3. 11. Message print (DE/IT only)
In this mode, all the message data, which are used for displaying indica-
tion and list print, are printed as a contrast table of the selected languge
and English.
3. 12. Flash memory check
Data is written into and read from the flash memory to check data con-
formity. When the unit enters this mode, the check is started.

• Soft switch function description
SW-A1 No. 1 Protect from echo
Used to protect from echo in reception.
SW-A1 No. 2 Forced 4800BPS reception
When line conditions warrant that receptions take place at 4800 BPS
repeatedly.
It may improve the success of receptions by setting at 4800BPS.
This improves the receiving document quality and reduces handshake
time due to fallback during training.
SW-A1 No. 3 Footer print
When set to "1", the date of reception, the sender machine No., and the
page No. are automatically recorded at the end of reception.
SW-A1 No. 4 Length limitation of copy/send/receive
Used to set the maximum page length.
To avoid possible paper jam, the page length is normally limited to 0.6
meter for copy or transmit, and 1 meters for receive.
It is possible to set it to "No limit" to transmit a long document, such as a
computer print form, etc. (In this case, the receiver must also be set to
no limit.)
SW-A1 No. 5 CSI transmission
(CSI TRANSMISSION) is a switch to set whether the machine sends or
does not send the signal (CSI signal) informing its own telephone No. to
theremotefaxmachinewheninformationis received. When "nonsending"
is set, the telephone No. is not output on the remote transmitting ma-
chine if the remote transmitting machine has the function to display or
print the telephone No. of receiving machine, using this CSI signal.
SW-A1 No. 6 DIS receive acknowledgment during G3 transmission
Used to make a choice of whether reception of DIS (NSF) is acknowl-
edgedafter receiving two DISs(NSFs) or receiving one DIS(two NSFs).
It may be useful for overseas communication to avoid an echo sup-
pression problem, if set to 1.
SW-A1 No. 7 Non-modulated carrier for V29 transmission mode
Thoughtransmissionof a non-modulated carrier is not requiredfortrans-
mission by the V29 modem according to the CCITT recommendation, it
may be permitted to a send non-modulated carrier before the image
signal to avoid an echo suppression problem. It may be useful for over-
seas communication to avoid an echo suppression problem, if set to 1.
SW-A1 No. 8 EOL (End Of Line) detect timer

of trouble, without using a G3 tester or other tools.
When communication FSK data transmission or reception is made, the

is analysed and printed out. When data is received with the line monitor
(SW-A4 No. 8) set to "1" the reception level is also printed out.

Normally set to "0". If set to "1", the transmission speed and the recep-
tion level are displayed on the LCD. Used for line tests.
SW-A5 No. 1, No. 2 Digital line equalization setting (Reception)
Line equalization when reception is to be set according to the line char-
acteristics.
Setting should be made according to distance between the telephone
and the telephone company central switching station.
SW-A5 No. 3, No. 4 Digital line equalization setting (Transmission)
Line equalization when transmitter is to be set according to the line
characteristics.
Setting should be made according to distance between the telephone
and the telephone company central switching station.

SW-A5 No. 5, No. 6 Digital cable equalizer setting
(Reception for Caller ID)
Line equalization when reception for CALLER ID is to be set according
to the line characteristics.
Setting should be made according to distance between the telephone
and the telephone company central switching station.
SW-A5 No. 7 Error criterion
Used to select error criterion for sending back RTN when receiving im-
age data.
SW-A5 No. 8 Anti junk fax check
When using theAnti junk fax function, set to "1".
SW-A6 No. 1 Reserved
Set to "0".
SW-A6 No. 2 End buzzer
Settingthisbitto 0 will disable the end buzzer(includingtheerror buzzer/
on-hook buzzer).
SW-A6 No. 3 Disconnect the line when DIS is received in RX mode
Bit1=0: When DISsignal is received during RX mode, the line is discon-
nected immediately.
Bit1=1: When DISsignal is received during RX mode, the line is discon-
nected on the next tone.
SW-A6 No. 4 Equalizer freeze control (MODEM)
This switch is used to perform reception operation by fixing the equal-
izer control of modem for the line which is always in an unfavorable
state and picture cannot be received.
* Usually, the control is executed according to the state of line where
the equalizer setting is changed always.
SW-A6 No. 5 Equalizer freeze control 7200BPS only

mission mode (User press the START key after waiting for the fax an-
swering signal from handset or speaker).

Set to "0".
SW-A6 No. 8 Modem speed automatic fallback when RX level is
under -40dBm
When set to "1", if fax signal level is under -40dBm during reception,
machine selects the slower modem speed automatically.
It is effective when noises occur on the received document due to the
long distance communications.

ble even if the setting time of recalls (SW-B1 No. 5 - No. 8) has been set
to some times. This soft switch is added in order to meet FCC.
