SJ745ex yellow ink print problem

[ratm92231]

Hello,

I would like to know if someone has had this problem before, it looks that when the printer uses yellow it keeps on printing on all the colors. I don't know how to explain this. I've attached a test print picture so you know what I'm talking about.

Any suggestions let me know, thanks

the control chip on the mainboard have problems.
Please first remove the yellow head cable, and print other colors to check the printing.and let me know the result.
