3-4-1. Main PCB
Content
In changing Main PCB, parameters must be registered to Main PCB ROM after the change. Because of the time
it takes to readjust and reconfigure these settings, and for ease of use and better printing quality, copy the setting
value to a PC (upload) before replacement, then write the copied settings back to the main PCB from the PC
(download) after replacement.
