2) From copy to the next copy: 30%

21 Recording paper running out

The fax can detect the no-paper condition by a photosensor. When the paper has run out in the local copy operation, the scanning will stop with “PAPER OUT/JAM” on the LCD and an ALARM LED turns on without an alarm tone. When the paper has run out while a message is being received and the no-paper reception is activated, the LCD display will show “MSG. IN MEMORY”, and the ALARM LED turns on.

The heater of the fuser unit is controlled within the predetermined temperature range by the thermistor. If the temperature of the heater exceeds the range, the LCD displays “PRINTER ALARM 4”.

Furthermore, the built-in thermostat in the fuser unit prevents the heater from being overheated even in the event of the failures in the above temperature control circuit.
