• The paper is in contact with the paper sensor when the power is turned on.
• The leading edge of the paper does not reach the paper sensor within a predetermined feeding
distance since the paper has reached the inlet sensor.
• The trailing edge of the paper does not pass over the paper sensor within a predetermined
feeding distance after the same has passed over the inlet sensor.
• The leading edge of paper does not reach the outlet sensor within a predetermined feeding
distance after the paper has reached the paper sensor.
• The paper is in contact with the outlet sensor when the power is turned on.
