Precautions On Replacing The Mc Unit - Duplo DBM-120 Maintenance Manual

4. PRECAUTIONS ON REPLACING THE MC UNIT

Fine adjustment data and customized sizes are registered in the EEPROM (nonvolatile memory) on the MC unit
(board). Therefore previous data will be lost when the MC unit is replaced. Note down the fine adjustment data and
customized sizes prior to replacement and input them after replacement. Also be sure to perform the following
procedures and checks after replacement.
(1) Initializing the memory
Turn on the power with the function button pressed. Keep pressing until initialization of the machine ends.
This procedure initializes data registered in the EEPROM (nonvolatile memory) on the MC unit (board).
(2) Checking the paper reference setting
Check the setting of the paper reference in the maintenance menu. If the setting at "Select Paper Ref" is not
appropriate, set it again. (Refer to "3-7. Changing the Paper Reference")
(3) Checking the fine adjustment data
Enter the fine adjustment mode and check the fine adjustment data. For settings other than 0, +1 to +9, –1 to –9,
the fine adjustment data memory will need to be initialized. Perform the following procedure to initialize. Turn off
the power, and while pressing the center button (function button) on the control panel, turn on the power again.
After this, enter the fine adjustment mode. Even if there is no need to set the fine adjustment data, be sure to
enter the fine adjustment mode.
(4) Inputting fine adjustment data and customized sizes
Enter the fine adjustment mode, and input the fine adjustment data and customized sizes noted down before
replacement.
