E733-0000: Printer communication error
[Description]
A communication error between the DC Controller PCB and the Main Controller PCB 2 was
detected at startup.
[Remedy]
Start remedy for error
at startup
Check if the LED on the
DC Controller PCB is
lit/flashing when
turning ON the power.
Yes
No
No
Check (connection and
conduction state of)/replace the
harness/cable, connector and
parts related to power supply.
(Refer to
[Related parts 2: Power supply].)
Check (connection and conduction
state of)/replace the harness/cable,
connector and parts related to
communication. (Refer to
[Related parts 1: Communication].)
Is the error cleared?
Is the LED lit/flashing?
No
Yes
It is highly possible
that power is not supplied
to the DC Controller.
It is highly possible that
signal is not detected normally
between the DC Controller
and the Main Controller.
End
Is the error cleared?
Yes
End
Collect Sublog and contact
to the sales company.
NOTE:
If the cause of the error cannot be
identified by analyzing Sublog,
it may require
investigation separately.

Before replacing the DC Controller PCB, back up the service mode data (approx. 2 min) and
restore the backup data after the replacement so the data may be able to be protected.
