Question about Canon PIXMA MP780 All-In-One InkJet Printer

1 Answer

Color print quality

Color printing by of my PIXMA MP780 is light and lacks definition. I would assume that there is a problem with the magenta cartridge. But the display indicates that the magenta cartridge has ink, and there are no problems indicated with nozzles or anything else. Any ideas?

You can clean the head from the printer software or take it out and run some warm water over the ink ports/ink jets.

Are the ink tanks securely clicked in place? they can come loose easily

printers will only print black and white unless you change the print settings to be color
before you go to print find the printer settings or options and make the default setting color
that way it will print exactly what is sent from the computer to the printer

Canon Pixma MP780. Recently my color ink


Have you checked to see if the jet area on the bottom of the ink cartridge has a blackish sludge on them? It might be that the area that the print cartridges are purged/cleaned to one side of the printer (sometimes called a service station, or spitoon) has built up excess ink that has gotten thick and high enough that as the carriage goes over that area the bottom of the cartridge gets polluted with the blackish sludge. It will work slightly into the jets where the ink comes out and cause discoloration, even after you change the color cartridge. Open the unit to look inside with a flashlight for build ups and clean it (if you find some) with disposable things like cotton swabs, coffee stirrers, whatever you have that wont damage anything inside. Another cause could be mixing of the cyan and magenta and yellow somehow inside making a dark color representing black - but replacing the cartridge would cure it immediately.

Print quality poor for mp780. Had s800 which


Hi,

There seems to be a calibration problem. Follow the calibration test from the manual.

If you are using original cartridges, go to canon for repair.

Prints all yellow, with some blue and black, no brown


the problem is very simple the magenta ink the cartridge is over or the head is been blocked from where the magenta ink comes out,
because red colour requires ---yellow plus magenta(pink)----to make it red.and ----dark yellow plus magenta(pink) -------- for brown colour.

Color problem


Chances are your othe cartridges were low...

When you install a new cartridge your printer does a head cleaning, and it uses alot of ink...

If the others were low, your printouts will show magenta as its the only color left...
