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

1 Answer

Installed Office Depot ink cartridges, BCI 6 C and Y in my MP780. Worked ok at first, but then started getting "wrong cartridge" msg, Per canon rep, turned off mach, disconnected power, took out print head and found cyn cartridge leaking. While cleaning up print head, noticed cyan stain on underside of print head. Installed an OEM cyn cartridge, but left the Office Depot yellow in. Turned it back on . Same "wrong cartridge" msg. Also noticed display still showed the cyn almost empty. I have used Office Depot before with no problems. Bur now wondering if I should change the Office Depot yellow and only use OEM's.from now on. If print head is bad would replacing it solve my problem? Hate having to buy a new printer if a $50.00 print head will do the trick.

This is an example of why 2nd class refills are junk. I would try to gently clean the printer out. While a lot of people disagree with this advice, a mixture of 90% alcohol in a tiny pipit works well. Then use some lint free q-tips. Most cartridges have electronic chips on them that report the status of the cartridge. Refilled ink cartridges may have bad or defect chips.

Wrong Color Printing


Hi,
Type "print nozzle test" in the search box and click Search. Perform a nozzle test, and if the colors match what are on the instructions, your print head and inks are OK.

(1) If the print head and inks check out OK, type "wrong colors on print" in the search box, and you will see several troubleshooting steps you can try.

(2) If the nozzle test colors are off, confirm that you are using BCI-6 inks for all three colors and the small black tank. You should only have a BCI-3 tank in the large black position. If you have all the correct inks, your machine probably needs to be serviced/ repaired.

Thank

"wrong cartridge"- Printer is giving us a "wrong


Hi Sherri

I am having the same problem with my MP780 mine started doing the same thingafter deciding to use Calidad inks the large black ink leaked into the yellowink (stick to canon inks).

What I have done so far with no success -
Replaced the ink cartridges with new ones supplied by Calidad, still the sameproblem.
Removed and cleaned the print heads manually and to my surprize after soakingin warm water and multiple cleanings for over 1hr black ink is still coming outof the yellow ink head.
I still get the same message after all I have tried...

One thing I did manage to do is prime the yellow ink and got it flowing throughthe head again but it's still mixed with black... I wonder if you may have runout of magenta and dried the head...

Try priming the magenta ink by removing the head (don't touch or wet the metalcontacts at the rear, the ink heads are on the bottom) place on a clean lintfree cloth (or I just used damp tissues then dry tissues) you should get onelong black strip and two cyan, two magenta and two yellow strips on the tissue,if you do not then try priming by replacing the magenta cartridge and gentlypumping the cartridge up and down repeat until you get the ink flowing.

Replace the head and cartridges, press ok, turn the printer off then reset.

Let me know if it works or if you come up with another solution that works as Iam still trying to figure out how to fix mine.

Good luck

Without realizing my mistake, I erroneously installed #3e Y-M-C ink cartridges instead of the correct #6 cartridges in my MP780. It worked fine for several days, then I got a message saying the printhead...


The fact is when you compare the cost to get a new printer to replacing your printhead and cartridges you find you may want to go for a new printer instead. The difference usually is not be worth it.

Good luck & God bless!

I think I put in a wrong colored toner cartridge. Pages printing in wrong colors. Can't find a list of the cartridges I should be using.


The make and type of cartridge is generally given in the users handbook/manual provided with the printer. If you do not have that ,you can log on to Canon web site and then go to support. Select your printer model and you can find the the specification of cartridge to be used with your printer. The list of the cartridges is given below: BCI-3eBk Black ink tank, BCI-6Bk Black ink tank, BCI-6C Cyan ink tank, BCI-6M Magenta ink tank, BCI-6Y Yellow ink tank You can also go the this link and download the manual if you do not have the same http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/pixma_ip_series/pixma_ip4000#Overview

With this type of printer you need to have a full black cartridge to print black and white. The new Canon BCI-24 black cartridge from Staples is only $8.29. These cartridges are even cheaper from refillers. I recommend Cartridge World or Office Depot for printer cartridge refills.
