I have a Canon Pixma Pro-1 printer for three years, I print about 100 photos 10 x 15 cm a month. I use only genuine Canon inks.
She started printing the stripes on the photo regardless of paper (glossy, matt, satin). The test print is OK, the CD print or documents prints clean.
Cleaning and deep cleaning did not help. Automatic alignment of the print head did not help. But when you manually align the print head, it does not print the correct H, K, and T columns. I cleared the print head in distilled water and I changed the PC and C inks for new ones but did not help.
