6.5.2 Main PCB Assy
 Outline
If main PCB assy has replaced, various parameters must be registered to main PCB assy 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 assy from the PC after replacement.

Work procedures
1. Turn off the main power supply and remove the power plug
from the main body.
2. Remove the electrical box cover .
3. Disconnect all connectors on PCB.
If it is impossible to upload the parameters, note the necessary adjustment values.
Then manually register the values after replacing the main PCB assy.
After turning off the sub and main power switches in order, unplug the power code.
Check if no electric charge is remaining in the PCB.
Refer to the "4.5.2 Electric charge checking when replace the Electrical Parts"
It is very dangerous if sleep mode functions mistakenly during the operation.
Moreover, the PCB may be damaged in case electric charge still remains inside.
Also there is a possibility of electric shock because of high power voltage applied the high-pressure part
of the power supply PCB assy. Take care to avoid contact with it.
