    [Jamming] MP 171 Jamming at ADF - double side only

    Hi all,

    There is a first time i had seen something like that on whole range of Stella's. Every time you want to make double sided copy jams at df. Single mode works perfectly. It seems to be jamming once m/c scans first page. It does go throgh an inverter but then looks like paper feeds out too far as it can not go back . Parts already replaced - both motors, solenoid, adf board, 3 sensors ( AW02 0155 Photointerruptor:Paper Size Sensor,photo reflection sensors x2) clutch, one way bearing,

    Any ideas ?
