Remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and connect the Printer to be detected and installed. Check printer properties to see the ink levels.
Use head cleaning before a test is taken .

You are doing well, keep trying the ink as it is a new cartridge has to still come through.

Do a few more deep cleans and then print some test pages. You may need to do this a few times.

Take care!

Pink and blue streaks on right side of page


most probably your "soak" pad need exchange. check your manual and change it. when you "deep clean" heaps of ink is absorbed into the pad exacerbating the problem, not solving it.

remove cartridges first and check them for existence of any foreign matter,

check for presence of debris under the head and parking place, remove if any,

i would suggest cleaning of printheads, albeit this can be risky (check first if your ink is soluble in water, isopropyl alcohol or methylated spirit, use that which solve your ink without clumping as cleaning agent), remove cartridges and allow appriopriate solvent to sit few second on metal rasters, wipe them with clean absorbing tissue and repeat procedure till solvent is "sinking" through the net.

remove old and install new absorbent pad under the print heads,

re-install inks, print rest page and then "normal" page. ink on first test page maybe very weak as solvent need to go through first.

if you follow the steps correctly, your should have clean print on the end.

"deep cleaning" is just waste of time, effort and ink. it is better if you create yourself a document with alternative lines of all three basic colours and black and then print it.

Color copy not accurate from pixma mp780 it comes out yellowish


I would try using a set of OEM cartridges. Make sure to run deep nozzle cleaning and alignment.
Some aftermarket cartridges are not as well quality controlled and tend to be inconsistent and gum up the nozzles.
If you need a source for good aftermarket cartridges try LD Products online.

Magenta printing as yellow


Well, first off, are the alignment, and nozzle check sheets looking good? If not, then work on that. If so, then we have a problem. Try creating a test sheet in Word. Make red, yellow blue & black text and see if anything else prints wrong. Get back to me!

Some colours not printing


I bet you are using non genuine ink, the MP780 will not put up with that ink, you will need a new printhead and maybe a purge unit. Take the machine to your ink supplier and get him to fix it as he supplied the ink
