Main PCB
Caution:
Before replacement of the main PCB, back up the machine information and user
setting information, referring to
Chapter 9, Section 9.4.11 "Backup of Machine Information
(Function code 46) (User-accessible)."
After replacement, restore the backed up information to
the new PCB. Failure to do so requires replacing also the ink absorber box and flushing box
after replacement of the main PCB.
Caution:
Before accessing the main PCB, make sure that the power cord is unplugged from the
electrical outlet and the telephone line (MFC only) is disconnected; otherwise, an electric shock
could occur.
Caution:
At the time of removal of the main PCB, untightening screws should be preceded by
disconnection of the harnesses and flat cables, and at the time of installation, connection of the
harnesses and flat cables, by tightening of screws. Observing this sequence prevents harnesses
and flat cables from getting crushed or damaged by screws or screwdrivers.
(1) Disconnect the following harnesses and flat cables from the main PCB
Caution:
Do not remove the screws from the main PCB before disconnecting harnesses
and flat cables.
Note:
After disconnecting the flat cables, check that each cable is not damaged at its end or
short-circuited. When connecting the flat cables, do not insert them at an angle. After
insertion, check again that they are not at an angle.
