https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/MP530-stopped-doing-quot-black-only-quot-copying/m-p/99132#M33201 <P>I replaced both black ink cartridges, which were low. That did not help. I then cleaned the print heads and did an automatic print head alignment. I got an error message indicating the automatic alignment did not work properly. W<SPAN>hen I tried manual print head alignment, t</SPAN>he pattern that printed was totally missing columns "A" and "L" as well as the column and row labels. I tried making manual adjustments for the columns that did print, and I changed "A" to -3 and "L" to +1 (just guesses), but that did not help. The color printing is working fine. Any ideas as to what I can try next to fix this would be greatly appreciated.</P> Tue, 17 Jun 2014 17:42:50 GMT DanaLaFontsee 2014-06-17T17:42:50Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/MP530-stopped-doing-quot-black-only-quot-copying/m-p/99132#M33201 <P>I replaced both black ink cartridges, which were low.
