"Internal cooling fan is
active."

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.

The machine may perform periodic
maintenance during operations. The

as number of prints, paper size, and
paper type. Wait for the machine to
