Changed black ink cartridge to LD brand. Now printer only prints every few lines. Skips lines of black text. Will print other colors of text but the colors are very light--not as dark as they should be, but they print every line. The black only prints a few lines and skips lots of lines inbetween. Is it to do with the LD brand of black ink cartridge?

I've had good experiences with quality non-Canon ink tanks. It sounds like the print head needs cleaning or you are running out of ink. You can buy print head cleaning kits on ebay or so it yourself with distilled water by soaking just the bottom of the print head in it, keeping the printed circuit contacts out of the water. Dab it dry with paper towel and try using the cleaning cycle then see if all the lines print. You can, I believe, also buy a replacement print head for this printer if you don't get anywhere with cleaning it. I've had good experiences with quality non-Canon ink tanks.
