7. TROUBLESHOOTING
CAUTION
Never turn off the main power switch when the power LED is lit or flashing. To avoid damaging the hard disk or memory, press the operation power switch to switch the power off, wait for the power LED to go off, and then switch the main power switch off. NOTE: The main power LED ( ) lights or flashes while the platen cover or ARDF is open, while the main machine is communicating with a facsimile or the network server, or while the machine is accessing the hard disk or memory for reading or writing data.
7.1 SERVICE CALL CONDITIONS
7.1.1 SUMMARY
There are 4 levels of service call conditions.
Level A Definition To prevent damage to the machine, the main machine cannot be operated until the SC has been reset by a service representative (see the note below). SCs that disable only the features that use the defective item. Although these SCs are not shown to the user under normal conditions, they are displayed on the operation panel only when the defective feature is selected. The SC history is updated. The machine can be operated as usual. Turning the main switch off then on resets SCs displayed on the operation panel. These are redisplayed if the error occurs again. Reset Procedure Enter SP mode, and then turn the main power switch off and on. Turn the operation switch or main switch off and on.
