"Currently printing at low
speed due to low voltage
power supply."
Printing has slowed down
because the power supply
voltage is low.
This is not a malfunction. You can
continue printing although the printing
speed is low.
"Internal cooling fan is
active."
Large print runs will cause
the machine's interior to heat
up, triggering the cooling
fan.
The fan will emit noise, but this is
normal and the machine will be
operable while the fan is running.
The amount of paper that can be
printed and the total operation time
until the fan starts running depends on
the temperature of the location at
which the machine is installed.
