Windell,
I checked and re-confirmed that my ABC steps are YES. I went on to step 4, adjusting current, I follow the procedure and it took two clicks to get the motors running smooth and no funky sounds. BTW what is the use of the Sand Paper? :)
I did not have chance to do an actual print test to see if color issue is still there or any prints are same as on the screen. I will do that tonite.
Thank you so much for such a detail and helpful response. Best Customer Service!!!!
