Prior to proceeding with the disassembly procedure,
(1) Be sure to back up the machine information and user setting information into an external
memory. If the main PCB is replaced, restore the backup data to the new main PCB after
completion of reassembling. Failure to back up the machine information requires the ink
absorber box and flushing box to be replaced after replacement of the main PCB.
For detailed backup and restoration procedures, refer to Chapter 9, Section 9.4.11 "Backup
of Machine Information (Function code 46) (User-accessible)."

- Power cord from the electrical outlet (or from the machine in the case of 200 V series)

connected (if not, remove the EXT cap)
