I have had this printer for about 8 months with no issues. The print quality started to decline last week. I switched to highest quality, which worked for a few days, but now is bad too. Now the black printing is barely showing. I have done multiple "deep cleaning" in the Maintenance and performed an Ink Flush. I have it set on the highest quality, which is really slow. I held down the power button for 10 sec and then unplugged for 15min. Nothing works.
