IP4200 Printing wrong color

This typically happens when you get a clog in a cartridge or a leak in a cartridge. Not necessarily the heads.....
The cartridge cloggs/leaks and the printer tries to **** ink from the clogged/leaking cartridge. As the cartridges are located right beside each other the ink is sucked from the adjacent cartridge where it mixes with its own ink...

Heres what to do......
Runs a test to determine where the problem lies.

For the ink that is printing in the incorrect color (Change that cartridge) and for the color it is printing in (Change that cartridge too).

Yup you'll need to change at least 2 cartridges. One has sucked up the wrong color and mixed with its own inlk, and the other is the defective cartridge...

Note: If it is caused by leaking make sure when you change the cartridge that both new cartridges are seated well. Otherwise one can leak again and contaminate your other cartridges.

Run a few cleaning cycles (To get the mixed ink out of the cartridge heads)...

All should be back to normal....

How have you cleaned the nozzles? Have you went inside the printer and cleaned them or have you just done it through the program on the computer. If thats the case, you should clean the nozzles inside the printer with a cutip. Otherwise, if you have warranty, you could ask cannon for reccomendations. You might just have clogged heads, so the cutip should work. Hope this helps! :)
