Error and maintenance messages B
As with any sophisticated office product, errors may occur and consumable items may need to be 
replaced. If this happens, your machine identifies the error or required routine maintenance and 
shows the appropriate message. The most common error and maintenance messages are shown 
below.
You can correct most errors and perform routine maintenance by yourself. If you need more help,

Cooling Down
Wait for a while
The temperature of the drum 
unit or toner cartridge is too 
hot. The machine will pause its 
current print job and go into 
cooling down mode. During the 
cooling down mode, you will 
hear the cooling fan running 
while the LCD shows Cooling 
Down, and Wait for a 
while.
Make sure that you can hear the fan in the 
machine spinning and that the exhaust outlet is 
not blocked by something.
If the fan is spinning, remove any obstacles 
that surround the exhaust outlet, and then 
leave the machine turned on but do not use it 
for several minutes.
If the fan is not spinning, disconnect the 
machine from the power for several minutes, 
then reconnect it.
