You beter change COLOR REGIST ASSY.

thank you.....

But first you said:


I have replaced PRCB board and PGC sensor, but the machine still C-4521.

It is better to change whole assy then just sensor.
And if you changed PRCB you need to update firmware.
You must always follow necessary procedure when replaceing parts.

Try again that procedure first for PRCB then for sensor assy.
