Toshiba 3511 C020 Code

[gitana1983]

Hello.... happy friday to everyone....
I have a Toshiba E Studio 3511 with error code C020. The developer seems to be rotating normally and everything seems normal in general..... any idea about another thing that may cause this error?
Where else to look? any reset?

Seems is not enough. Pull out black developer unit and check if it is rotating by hand easily.

Generally for this problem procedure is as follows:

[C020] Developer motor abnormality
Is the developer unit motor working? (Perform the output check: 03-112/162)
NO 1. Check if the connector J578 of the developer motor is disconnected.
2. Check if the connector CN348 on the LGC board is disconnected.
3. Check if the connector pins are disconnected or the harnesses are open
circuited.
4. Check if the conductor patterns on the developer motor board and LGC board
are short circuited or open circuited.
5. Replace the developer motor.
6. Replace the LGC board.
YES
1. Check if the PLL lock signal CN348-B6 pin output from the LGC board is always level “L”.
2. Check if the voltage supplied to the ASIC input terminal IC38-150 pin is always “L”.
3. Replace the LGC board.
