After Pre-Feed started for the first sheet (DADF Feed Motor On (CW)) in Simplex and
Duplex, the DADF Pre Registration Sensor did not turn ON within the specified time.
•
After Pre-Feed started for the second sheet onwards (DADF Feed Motor On (CW)) in
Duplex, the DADF Pre Registration Sensor did not turn ON within the specified time.
