Question about Canon PIXMA MP760 All-In-One InkJet Printer
Hadn't printed photos in awhile, but when I went to do some the black is dull and full of lines. Using all Canon ink (bought all new to see if it helped). Ran head alignment, print head cleaning, deep head cleaning, roller cleaning - nothing helps the dullness, though I did get the lines to disappear for a couple photos. Help! I scrapbook and I need to be able to print nice photos.
Take the cartridges out and also the printhead and set the nozzle of the printhead on a 5-sheet pile of kitchen paper that was make wet in the middle with some lukewarm demineralized water ( water for an iron )there is not much necessary if there are clogged nozzles deep inside the printhead buy cartridge flush different methode for printers to find

SOURCE: smeared lines
Okay, this was the problem I posted a few days ago. It's fixed now, so in case you have the same problem with smearing, here's what the help desk from Canon suggested: Open the cover and remove the ink cartridges. There is a gray lever in front of the cartridges. Lift this lever and the printhead can be easily removed.
Our printhead had a buildup of black ink on the surface. I carefully removed this with rubbing alcohol. I let the printhead dry and replaced everything. No more smearing. Imagine a help-desk that actually helped!

My MX700 is 1 year old and I to have issues:
2) Says it's out of paper when there is paper in it. Shutting off an Turning on usually helps
3) Feeds multiple pieces of paper at once!

The ink tanks may be full but sometimes the pins that connect the cartridges to the printer may have dried up ink on them preventing the ink from flowing. You can try to swab these with a bit of rubbing alcohol on a Qtip and letting it dry for moment or two. I would strongly suggest doing a couple of deep cleanings first and try test printing of the individual colours separately in a program such as paint to see which colour is affected.

Tips for a great answer:
CANON MP780 BLACK DOES NOT PRINT
This is what works for me. Try at your own risk. I cleaned both areas.
Perform a nozzle check using the Canon software under "maintenance." If the nozzle check prints successfully, the problem is most likely not with the printhead. Otherwise, 1) Lift up the lever above the ink cartridges. Take the ink cartridges out. Put them in a plastic zip lock bag. 2) The container in which the ink cartridges sit is removable. The container is inside the moving mechanism. The container is the printhead. Tilt it slightly and pull up. This should come out easily. 3) There are round pads under which the ink cartridges sit in the printhead you removed. The large one is black. On the underside of the printhead are small slits. The **** separated from the others is black. Fill a syringe with Windex. a. Run warm water over the printhead until no more ink comes out. b. Fill the areas where the round pads are with Windex. c. Set the printhead on some paper towels. The liquid will soak through and come out the underside along with the ink. Repeat steps a-c until no more ink comes out, but at least 10 times. 4) Let the print head sit and dry for two hours. Put everything back in the printer. Unplug the printer. Plug in the printer. Turn the printer off. Turn the printer on. Do a clean cycle.
CLEAN PURGE MECHANISM:
You will need a light. 1) Unplug the printer and move the printhead all the way to the left. On the far right are two rectangular basins. The smaller one is black. Take your fingernail or a tweezers and lift out the sponge pad (do not drop it). Soak the sponge pad in Windex until it turns white. Plug in the printer. 2) Fill a syringe with Windex. a. Fill the basin with liquid. b. Let it soak for 5 minutes. c. Turn the printer off. d. Turn the printer on. Repeat steps a-d until you see a small hole in the basin. e. Put the syringe over the hole and fill the basin, pushing the liquid into the hole. f. Let it soak for 5 minutes. g. Turn the printer off. h. Turn the printer on. Repeat steps e-h 5 to 10 times. 3) Put the sponge pad back in using your fingers (do not drop it). Unplug the printer. Plug in the printer. Turn the printer off. Turn the printer on. Do a clean cycle.
