7. Paper Eject Miss
< Phenomenon>
7-1. When printing starts without master processing, paper feed does not start but
paper wrap indicator blinks and the drum stops rotating.
< Possible causes>
1. Contamination build up is on the
second drum position sensor [A] main-
tains the sensor ON condition (inter-
rupted). When printing starts, the first
paper delivery sensor is OFF, and the
second drum position sensor [A] is ON
as mentioned above; therefore, the
Paper Wrap indicator lights.
2. The second drum position sensor [A]
is faulty.
< Countermeasure>
1. Clean the light emitting and light
detecting surfaces [B] of the second
drum position sensor [A].
2. Replace the second drum position
sensor [A].
