Just set up the printer and ran a test print. Paper runs through. but only a few faint black lines show up. I cleaned the printer head and there seems to be enough ink in the cartridges. The printer has sat unused for a long time. Otherwise everything seems to be ok.

Here is the link to the user guide if you need it; http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=257&modelid=10439 If you have performed all the operations in there with no success, then the part of the printhead that is under the 6bk has some blockages. This is best cleaned by dripping some ink flush solution (use gin if you have none) into the print head from above (just at the point where the hole on the ink cartridge would sit. Very gently swab with a q-tip from below with more fluid. After a day or so with the fluid penetrating from the top, clean the bottom again, clean out any excess fluid you can from the top (don't get any q-tip fluff in there). Then run a clean/test again. Hopefully this can solve your problem after a few cleans, but blocked Canon printheads are not always unblockable. You can purchase the complete replacement printhead, although I wasn't able to find a price - this link for service; http://www.usa.canon.com/consumer/controller?act=ServiceLocatorAct&fcategoryid=184&modelid=10439 Hope this helps :)

SOURCE: Canon Pixma ip3000 printer, changed black ink

i had the same problem and just repeated the cleaning and testing, eventually the black showed up but took more than a few repetitions

SOURCE: Canon MP980 prints horizontal pink lines across

try to change the color ink. horizontal banding (the pink or other color lines appearing means horizontal banding) when there is a problem on one of the heating element of the printer head. since almost all canon printers have head built in the inks, replacing the faulty ink will solve the problem. if not then the controller of printhead on the carriage and mainboard needs to be checked.
