So i have got this printer circa 3 months ago, and at one point it has started to print with lines, so I did the cleaning program on it. Ever since, I have had to do multiple cleanings in a row. None had perfect results, ranging from a black line on the yellow grid and thicker/smudged lines on the cyan and magenta grids. The latest nozzle check i did was today and it came out with two black lines on the cyan grid and a missing spot, and 2 thicker lines on the magenta and black ink. Should I send it back in the warranty repairs?
