Make sure that the data-in LED (
) is not on before you go into the SP mode. This LED
indicates that some data is coming to the machine. When the LED is on, wait for the
copier to process the data.
5.1.1 USING SERVICE PROGRAM MODES
Use the service program modes (SP modes) to check electrical data, change operating modes,
and adjust values.
The Service Program Mode is for use by service representatives only so that they can
properly maintain product quality. If this mode is used by anyone other than service
representatives for any reason, data might be deleted or settings might be changed. In
such case, product quality cannot be guaranteed any more.
