● Shutdown sequence
Before turning OFF the main power switch, it is necessary to perform HDD completion
processing (to preventdamage on the HDD), cooling of the internal printer (to prevent fixed
toner due to high temperature) and exhaust (to prevent smeared image due to chemical
reaction of ozone in the machine and photosensitive drum). This sequential processing is
called “shutdown sequence” and was executed on the legacy models manually (by holding
down the power supply switch on the Control Panel for a specific duration).
When the main power switch is turned OFF on the main body, Main Controller PCB 1 detects
this operation and then the shutdown sequence starts/executes automatically.
NOTE:
On the assumption that the shutdown sequence was not completed normally, the host
machine is shut down by the Relay PCB in approx. 120 seconds.
