■ Protective Function
DC power PCB of the host machine and the power PCB of options have the overcurrent
protective function and the abnormal high voltage protective function to prevent the power
circuit brokerage by stopping the output voltage automatically when overcurrent or abnormal
high voltage occur due to the problems such as short circuit etc on each load.
When an error occurs on 3VB (all-night power), all the power will be stopped.
An error occurs on the power other than above, all the power will be stopped except for 3VB
(all-night power).
When an error occurs on 3VB (all-night power), turn OFF the main power switch on the printer
unit and remove the part where the protective circuit has been activated, and then replace the
all-night power PCB (because the fuse of all-night power PCB is burnt.).
In other cases than above, turn OFF the main power switch of the printer unit and remove the
part where the protective circuit is activated. Wait for 3 min or more and turn ON the power to
reset the protective circuit.
