[Matoku]

Hi everyone,
Here I look for more solution regarding my Printer Sharp MX-M314N that comes up with error E7-14. What I have done is change the SCU pwb, scanner flate cable,CCD unitand the scanner unit but still the same. I also updated firmware. Any suggestion on my issues are really appreciated in advance.

Is the SCU PWB new? If it is run calibration. You need a scanner calibration sheet, check the manual for p/n.
