Had this problem suddenly appear. Removed ink carriage and cleaned contacts with medical isopropyl alcohol wipe. Placed folded paper towel under print head to bleed and clean print head. Then realised had two generic inks (No indication they were empty!) so replaced these with genuine HP. Re-assembled. All OK. Been an excellent printer for over 4 years, just genuine inks cost a fortune in OZ ($160) for full XL pack. And yes new ones look junk! So maybe another brand when replacement needed.
