3.3.1 Replacement of Main PCB

 Outline
If Main PCB Assy. has replaced, various parameters must be registered to Main PCB ROM after the replacement.
Considerable time is required to readjust and reconfigure these settings. Therefore, for ease of use and better printing
quality, copy (upload) the setting value to a PC before replacement, and write (download) the copied settings onto the
Main PCB from the PC after replacement.
If it is impossible to upload the parameters, conduct Parameter Draw to note the setting values.
Then manually register the values after replacing the PCB.
