Abstract
An image forming apparatus includes a sheet supply unit for supplying a printing medium; and a sheet discharge unit for discharging the printing medium after an image is transferred to the printing medium. Further, the image forming apparatus includes a transport path medium number storage unit for storing a transport path medium number; a discharge number storage unit for storing a discharge number; an upper limit print number storage unit for storing an upper limit print number; an addition unit for calculating an addition sum of the discharge number and the transport path medium number; a number comparison unit for comparing the addition sum with the upper limit print number; and a sheet supply stop unit for stopping the sheet supply unit when the addition sum exceeds the upper limit print number.
Claims10
An image forming apparatus, comprising:
- a sheet supply unit for supplying a printing medium;
- a sheet discharge unit for discharging the printing medium after an image is transferred to the printing medium;
- a transport path medium number storage unit for storing a transport path medium number or a number of the printing media in a transport path disposed between the sheet supply unit and the sheet discharge unit when the sheet supply unit supplies the printing medium and the sheet discharge unit discharges the printing medium;
- a discharge number storage unit for storing a discharge number or a number of the printing media discharged from the sheet discharge unit, and for updating the discharge number by adding one to the discharge number when the sheet discharge unit discharges the printing medium;
- an upper limit print number storage unit for storing an upper limit print number or a maximum number of the printing media that the sheet discharge unit is capable of discharging;
- an addition unit for calculating an addition sum of the discharge number and the transport path medium number when the sheet discharge unit discharges the printing medium;
- a number comparison unit for comparing the addition sum with the upper limit print number;
- and
- a sheet supply stop unit for stopping the sheet supply unit when the addition sum exceeds the upper limit print number.
