1) Reinstall the magenta unit correctly, But it still not clear.
2) Replaced the magenta developing, But it still not clear.
3) Replaced the FRB board, But it still not clear.
4) Replaced the PRCB Board, But it still not clear.
5) Replaced the wiring related to it, But it still not clear.
6)Checked and replaced all the switches, But it still not clear.

Even after doing a lot, the machine only displaying this error continuously.
Has anyone faced this problem.

Have you updated the firmware?
