Note:
* On HL-L9200CDW (T) and HL-L9300CDW (T), there are cases where the Key PCB
flat cable is affixed with the Panel relay PCB flat cable and Top cover ASSY using
double-sided adhesive tapes A and B in the halftone section.
In this case, be careful not to damage the flat cables when separating these two flat
cables or Key PCB flat cable and Top cover ASSY.
In addition, when assembling the flat cables, be sure to affix the two cables at a place
where too much force is not applied to the connector section.
Note:
- After disconnecting flat cables, check that each cable is not damaged at its end or
short-circuited.
- When connecting flat cables, do not insert them at an angle. After insertion, check that
the cables are not at an angle.
