Problems related to general use of the machine are described below. For problems related to the copy function, see page 6-3. For problems related to document filing, see page 7-31. For fax, printer, and network scanner/Internet fax problems, see the manuals for those functions. For peripheral device problems, see the explanation of the device. If the message "CALL FOR SERVICE. CODE:**-**"(Note) appears in the touch panel, turn off the main power switch and the power switch, wait about 10 seconds, and then turn the main power switch and the power switch back on. If the message still appears after turning the main power switch and the power switch off and on several times, it is likely that a failure has occurred that requires service.
