Punch Type; Eeprom - Ricoh B202 Service Manual

Punch Type

After you replace the punch-unit controller, specify the punch type
as follows:
1. Set the DIP switch [B] on the punch-unit controller board as
follows: 1 = ON, 2 = ON, 3 = OFF, 4 = ON [J].
2. Push SW1002 [C] to select a punch type. As you push SW1002,
the three LEDs [E][F][G] change as shown in the table. These
LEDs indicate which punch type you have selected.

** For the North Europe model
* Four the other models
3. Push SW1003 [D]. The LEDs blink.
4. Push SW1003 again. The controller stores the punch type in the

EEPROM.

5. Set the DIP switches as follows: 1 = OFF, 2 = OFF, 3 = OFF, 4
= OFF [K].
EEPROM
After you replace the EEPROM [A], make the controller initialize the
new EEPROM as follows:
1. Set the DIP switch on the punch-unit controller board as follows:
1 = ON, 2 = ON, 3 = OFF, 4 = OFF [L].
2. Push SW1002 and SW1003 at the same time. The controller
starts initializing the EEPROM.
3. Wait until LED1001, LED1002, and LED1003 light. This
indicates that the initialization ends.
4. Adjust the sensor voltage (! Sensor Voltage).
5. Specify the punch type (! Punch Type)
6. Set the DIP switches as follows: 1 = OFF, 2 = OFF, 3 = OFF, 4
= OFF [M].
