    Error in supply with Y Developing Assembly

    1. Check the damage of the Developing Coupling.
    If it’s damaged, replace the Developing Assembly.
    2. Check the damage of the coupling (with the Developing
    Assembly) at the Host Machine side.
    If it’s damaged, remove the Main Drive Unit to replace the
    coupling.
    3. Turn the motor as a single unit while the Drum/Developing
    Assembly is removed to check rotation of the Main Drive
    Unit.
    If it does not rotate, replace the Motor.
    If the above measures do not solve the problem, replace the
    Drum Driver PCB (UN4).
    If there still remains the problem, replace the Main Drive
    Unit.
    4. Remove the Hopper Unit and manually turn the Supply
    Input Gear to check rotation.
    If it’s results in NG, replace the Hopper Unit.
    Practice makes perfect
    If it ain't broke, don't fix it
    A picture is worth a thousand words
    If you want something done right, you have to do it yourself

    error code E027-0100 ~ 0400
    Black drive gear on the developer becomes stripped out
    Black + shaped drive gear develops a round center. It should be D shaped to match the drive shaft.
    Black drive gear is FC8-4338-000. The gear stripes out do to friction in the developer assembly. Replacing the gear may not resolve the problem.
    Open the developer and check for toner clumping and for a stuck auger. Rotate the auger by hand with the cover open and see if the toner moves freely.

    Thank you so much for the pictures and note. My black drive gear was broken. I search for the FC8-4338-000 but only see the white one FC0-3696-000 on precisionroller.com. I am not sure it will fit but will try to order them.

    Thanks.
    My old one was new type too and in black. It broke the smaller piece in the back (the long end only half cylinder with a shorter half cylinder close to the top). When I pulled it out, the shorter cylinder piece hanging
