TROUBLESHOOTING
Whenever the machine stops or operation is not possible, check the operation panel display for messages. In most
cases, these messages will give sufficient information to return the machine to an operating condition. In cases where
this information is not enough, check the list below for more information. This section describes problems concerning
copier features. For troubleshooting specific problems related to the printer, network scanner, and fax features, see
the separate manuals provided for these features. For problems related to other peripheral devices, see page 2-24.
