2.1.1 (A) Soft switch mode
In this mode, the soft switch are set and the soft switch list is printed.
1. Switch number selection
• Press START key for setting of the next soft switch. If the soft
switch number is the final, pressing START key will exit the soft
switch mode.
• Enter two digits of a soft switch number to set the switch num-
ber. If a switch number of nonexistent soft switch is entered, key
error buzzer sounds to reject the input.
2. Data number selection
The cursor position shows the data to be set.
Pressing # key or
→
key moves the cursor to the right. If, however,
the cursor is on data number 8, pressing # key or
→
key shifts the
cursor to data number 1 of the next switch number. If the switch
number is the final, pressing # key or
→
key will exit the soft switch
mode.
Pressing key or
←
key moves the cursor to the left. If, how-
ever, the cursor is on data number 1, pressing key or
←
key
shifts the cursor to data number 1 of the former switch number. If
the switch number is 1, pressing
key or
←
key will not move
the cursor and the error buzzer will sound.
3. Data setting method
Press the MENU 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 6.), the error buzzer will sound
with the process not received.)
4. 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.
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.
• 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
code function is specified from OFF to ON when the timer sys-
tem 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.
• 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 contin-
uous 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. How-
ever, registration is impossible to the program of the new contin-
uous serial polling when the continuous serial polling function is
OFF.)
• In addition, change of all soft switches during communication.
2.1.2 (B) Print area
According to the size of the specified sheet, the effective printing area
is printed.
2.1.3 (C) ROM & RAM check
This is an item to check if the loaded memory device acts normally.
• The memory devices shown in the following table are checked.
• In case that an error occurs in the device check, the alarm buzzer
shown in the table sounds.
Check device and alarm buzzer
*1: Work memory (SDRAM 8MB)
*2: Page memory (SDRAM 16MB)
(Example of display) In case that DRAM2 is erroneous.
• After the check is complete, the result is outputted.
• In case that an NIC and a PCL board are mounted, the version
information of the board is also printed on the result.
