Every other line has a line through it and the ink is light on those lines
Your machine is getting on in age a bit now sounds as it needs a new print head, if you remove the printhead and physically give it a good clean and replace back in machine and do a head clean and your prints are still bad you need a new printhead

The first suggested solution by the "wiz" is rediculous. If you had an owners manual it would tell you to do this.
What you really have to do is take the printer head off and GENTLY scrape the gunk off of it. Paper fibers build up on it.
-lift up on gray tab thing that is where you put the tink tanks in.
-pull out the black cartridge that holds all the ink tanks in place and look at the bottom.
-there is 5 small silver slits that color ink comes out and a long one for black ink.
-there maybe gunk all over the bottom - clean it off and you can use a folded piece of paper or gently with a pen cap.
-That gunk is filled with ink so be careful and do it over some paper towel.
-Place the blackcartridge (the printerhead) back in and use gary tab thing to close it.
-recheck to make sure the ink tanks are locked in
close the lid.
-then clean nozzle accesed through the printer "properties"
-Wont fix but makes it better. You need to get a new print head ($50) or try Canon Printhead Repair Kit ($10) or most effective, get a new printer ($50 without all of that stuff you still dont use)

Seem like blocked hole(s) on the color print head...
Most likely if there is a deep clean option then do it (may need a few times to unblock a hole or never).
Also get the printer physically cleaned up if you can see dusts inside (vrtical lines on color bars).
