Probable Cause and Faulty Parts
<Cause>
1. No paper was loaded.
2. During feeding, the paper did not reach the
paper-end sensor.
3. During feeding, the paper's bottom edge
missed the paper-end sensor.
4. The ASF sensor did not return to its initial
position and the paper-end sensor concluded
that there was no paper. (ASF motor may be
out of sync.)
<Suspect Parts>
Paper feed section, sheet feeder unit, paper-end
sensor, logic board
<Cause>
1. The paper-end sensor still detects the presence
of paper even after 23 inches of paper ejection
operation.
2. The ASF sensor did not return to its initial
position and the paper-end sensor concluded
that there was no paper. (Out of sync.)
3. During paper feeding abnormal timing caused
the paper-end sensor to still detect paper.
<Suspect Part>
Paper feed section, paper-end sensor, logic board
