2. Specification change Canges have been made to the electrical circuitry, and the functions of the NCU board have

been integrated with those of the SCNT board. In this Service Reference Manual, detailed

explanations of the electrical circuitry have been omitted (to respect the decision not to disclose

detailed information in technical documentation, e.g., on ICs).

3. Setting the Language and CountryWhen 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.

6

4. Setting the Summer TimeSome 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 Cartridge5.1 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 inresponse to PPS-EOP. If, however, the other machine has a problem incompatibility in relation to BFT, it will return FDM and the communication willend in error.NOTE

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 madeunder 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 madeunder 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 shiftwill be made to redialing mode. Redialing may be enabled/disabled, and thenumber of redialing sessions depends on user settings.

NOTE
