CAUTION
When servicing any printed circuit board, be sure to wear an anti-static wristband to ensure
proper grounding. If not, static electricity built on the human body may cause damage to electric
parts mounted on the board.
NOTE
With board version N or later, the software version of the machine should be updated to A09 or
later. Earlier software versions do not support a newer LSI (discontinuation supported) on the
