Error and maintenance messages

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

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

for several minutes.
If the fan is not spinning, disconnect the
machine from the power for several minutes,
then reconnect it.
