Hello John,
Just wondering if this worked for you. Perhaps you can let me know what was and done and what parts were changed. I am having the same issue with 577DW. Clearly, this is a manufacturers issue since it is across several page-wide lines. The only thing that fixes it is pulling the power cord and replugging it. I hope you have had some success because HP did not help either. I will give it a shot to fix, otherwise, I am ditching the brand once and for all.
