MEMO
MAC address information is changed after replacement of the Main Controller PCB.
Therefore, when the PC and the machine are connected by the network, the PC will
not be able to recognize the machine on the network. When the PC and the machine
are connected by the USB memory device, the PC will not be able to recognize the
machine if the USB ID is changed. It becomes therefore necessary to reinstall the
driver.
In the case of a model without fax for EUR (MF8540/MF8230), perform the following works.
MEMO
After replacing the Main Controller PCB, the value of the service mode (SDTM-DSP)
to set whether to display or hide the automatic shutdown menu becomes "0" (default
value).
In that case, the automatic shutdown menu is not displayed on the LUI of the machine.
To display the automatic shutdown menu on the LUI of the machine, it is necessary to
execute this process.
8. Setting of automatic shutdown menu display
Set 1 for automatic shutdown menu display in service mode (default: 0).
