My Pixma ip8720 was printing bad streaks just on black areas of photos. I thought print head needed cleaning so took it out and cleaned it. Now I have two different problems. The first is that the carriage will not center. It moves back and forth but will only park so the big black cartridge shows. I cleaned the white plastic strip behind the carriage as well as I can but that didn't change where it stops. Also none of the cartridges light up now. I hope someon knows a fix because I can't really afford a new one.
