6.4.1 EPL2 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 power unit box cover .
3. Disconnect all connectors on PCB.
If it is impossible to upload the parameters, conduct Parameter Draw to note the setting values.
Then manually register the values after replacing the main PCB assy.
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-pressure
part of the power supply PCB assy. Take care to avoid contact with it.

A button type lithium battery is used for this board. Warn following 1)~4).
1), Danger of explosion if battery is incorrectly replaced.
