Preparation
Prior to proceeding with the disassembly procedure,
(1) Be sure to back up the machine information and user data 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 9.4.10 "Backup
of Machine Information (Function code 46) (User-accessible)."
