Cautions:
The power cord must keep plugged from power at least 30 minutes since the power switch is turned off.
In case the power plug must be unplugged immediately after power-off for service purpose, pull out the
paper feed unit so that the fuser unit is away from developers to avoid toner lumping due to the heat from
the fuser unit.
