Data number selection
The cursor position shows the data to be set.
Pressing # key moves the cursor to the right. If, however, the cursor is
on data number 8, pressing # key shifts the cursor to data number 1 of
the next switch number. If the switch number is the final, pressing # key
will exit the soft switch mode.
Pressing key moves the cursor to the left. If, however, the cursor is
on data number 1, pressing
of the former switch number. If the switch number is 1, pressing
will not move the cursor.

Data setting method
Press the FUNCTION key, and the data at the position of the cursor
will be reversed to 0 when it is 1, or to 1 when it is 0. (If the soft switch
can be changed at the bit (Refer to

Outputting method of soft switch list
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.

Storage of data
In the following case, the data of the soft switches set will be stored.

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 com-
munication (including the batch communication) is set.)
Here, the memory 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.

(Note: This supports not only the operation protect of the op-
tional 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.)

OFF to ON of department control function during use of image
memory.

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.)

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
1 time <Short sound>
2 times <Short sounds>
3 times <Short sounds>
key
4 times <Short sounds>
5 times <Short sounds>
*6 times <Short sounds>
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.
