Summary
There are four levels of service call conditions.
Level
A
To prevent damage to the machine, the
main machine cannot be operated until the
SC has been reset by a service
representative (see the note below).
B
If the SC was caused by incorrect sensor
detection,
the SC can be reset by turning the main
power switch
off and on.
C
The main machine can be operated as
usual, excluding the unit related to the
service call.
D
The SC history is updated. The machine can
be operated as usual.
• If the problem concerns electrical circuit boards, first disconnect then reconnect the connectors
before replacing the PCBs.
• If the problem concerns a motor lock, first check the mechanical load before replacing motors or
sensors.
