3.3.1 Replacement of the Main PCB assy.
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.
List of replacement procedures
After turning off the sub and main power switches, unplug the power cord. Make sure to take 15
minutes before restarting the operation. 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 to the high-pres-
sure part of the DC power supply unit. Take care to avoid contact with it.
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.
