MG 7500 LINES IN PHOTOS

I JUST REPLACED ALL MY INK TANKS AND NOW MY MG7520 IS PRINTING LINES IN PHOTOS. IT WORKED FINE WITH CHEAP BRAND TANKS BUT NOT NOW THAT I SWITCHED BACK TO CANON. IM SURE ITS NOT THE TANKS BUT A WEIRD COINCIDENCE. i HAVE DONE DEEP CLEANING A FEW TIMES. i TRIED ALIGNMENT A BUNCH. MANUAL ALIGNMENT.  I HAVE USED NEARLY HALF THE INK IN THE TANKS AND HAVNT PRINTED ONE USABLE PICTURE
