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 or network scanner, and fax features, see the separate manuals provided for these features. For problems related to other peripheral devices, see page 2-24.
