OKI chip error
Ask:
OKI chip only changes one color, the display can not be used normally
Answer:
OKI chip replacement: customers must be filled with powder, four colors at the same time. The OKI series is quite special. It needs to change the four colors of the same manufacturer at the same time. If you just change one of the colors, the voltage of the chips of the two manufacturers is different, and it is easy to have problems.
