3. Setting the Language and Country
When you connect the power cord to an AC outlet for the first time, you need to select the
language for the LCD display. For some countries, you also need to select the country where
you are using the FAX machine. The FAX machine automatically switches the selectable
settings and the default settings in the menus to suit the selected country.
Follow this procedure to set the language and country.
After connecting the power cord, the display changes from PLEASE WAIT to DISPLAY LAN-
GUAGE.
Once you have selected the language and country, these setting menus will not appear next
time you connect the power cord.
Normally, the country selection window will appear when the user has selected a language.
A shift to the screen, however, will not occur if the user has selected any of the following for #5
TYPE in service mode:
EUROPE2, POLAND, ASIA, SLOVENIA, SINGAPORE, CHINA, SAF, HONG KONG, N.Z,
AUSTRALIA, UK, GERMAN, ITALY, SWEDEN.

4. Setting the SummerTime
Some countries adopt the summer time system that shifts the clock time ahead or back ac-
cording to the change in seasons.You can select if the time information in your FAX changes
to match your country summer time system and set the day and time when the summer time
begins and ends.
Operation at the Start of Summer Time
When the time selected for BEGIN DATE/TIME comes, the time stored by the machine is put
forward by 1 hour. Any delayed call falling whitin the affected time slot will immediately be
initiated when the time has come and the time has been put forward.
Operation at the End of Summer Time
When the time selected for END DATE/TIME comes, the time stored by the machine is put
back by 1 hour. Any delayed call falling whitin the affected time slot will immediately be initi-
ated when the time has come and the time has been put back.
If exactly the same date/time is selected for BEGIN DATE/TIME and END DATE/TIME, the
time is put forward/back by 1 hour repeatedly year after year.

5. Detecting a Residual Cartridge
5.1 Out line
This mechanism is designed to automatically cammunicate (ECM) printer information,
e.g., cartridge replacement, printer number.
All Bits of the other machine’s DIS must be set to [1]; in other words, the presence of a single
[0] will cause the communication to end in error.
Bit 27 ECM: [0]=Not Provided, [1]=Provided
Bit 53 Binary File Transmission (BFT): [0]=Not Provided, [1]=Provided
Bit 99 Simple Phase C BFT Negotiations capability
: [0]=Not Provided, [1]=Provided
The communication will end normally if the other party returns MCF in
response to PPS-EOP. If, however, the other machine has a problem in
compatibility in relation to BFT, it will return FDM and the communication will
end in error.

5.3 Conditions for a Call
The function is enabled when ACTIVATION is set to ON, and the number of prints and the
date currently registered will server as its starting point.
Condition 1:
When as many prints as set for PAGES under CRITERION have been made.
Condition 2:
When the cartridge runs out of toner, requiring replacement.
Condition 3:
When as many days as set for DAYS under CRITERION have been made.
Condition 4:
When a service error related to the printer has occurred.
A log on the following is used for the execution of this function:
Total number of prints made by the printer.
Number of prints that previously satisfied condition 1.
Date/Number of prints that previously satisfied condition 3.
Executing ALL CLEAR or CLEAR for Remote CRG will also clear the log data.
Condition 1:
When the difference between the number of prints and the number of prints that previously
satisfied condition 1 reaches the registered number of prints, a BFT file will be prepared and
a call made.
If the registered number of days under condition 3 is [0], no call will be made
under this condition.
Condition 2:
When the cartridge runs out of toner to require replacement, a call will be made.
Thereafter, no call will be made under condition 2 until the cartridge has been replaced and
the power has been turned off and then on. However, if condition 2 occurs once again when
the power is turned on after replacement of the cartridge, a call will be made.
NOTE
NOTE

11
Condition 3:
When as many days as set pass since the day on which condition 3 is satisfied and, in
addition, when 12 hours pass since the time at which ACTIVATION is set to ON, a call
will be made.
If the registered number of days under condition 3 is [0], no call will be made
under this condition.
Condition 4:
When a service error that is related to the printer occurs, call will be made.
Thereafter, no call will be made under condition 4 unless the error has been cleared and the
power has been turned off and then on once again. However, if condition 4 occurs when the
power is turned on once again after clearing of the error, a call will be made.
If a connection to the target machine fails when transmitting a BFT file, a shift
will be made to redialing mode. Redialing may be enabled/disabled, and the
number of redialing sessions depends on user settings.
