How do I remove the printhead Canon Pixma MP780

There is a lever I can lift up to the right of the printhead. I can remove the ink cartridges. How do I disconnect the cable to the printhead and remove the printhead specifically without breaking the printer? Thank you.

OK lift the gray lever up and remove the cartridges, look just below the gray lever and you will see two rounded protrousions inside towards the rear of the black box, grasp these protrousions with your thumbs and forfingers and gently pull toward you, ther may be some resestance but pull smoothly do not ****, the print head will come out.  There are no wires to disconnect the circuits are touch circuits.

Cannon Mp780 not printing yellow at all. Ink tanks are full.


CANON MP780 DOES NOT PRINT

This is what works for me. Try at your own risk. You may need to clean both areas.


CLEAN PRINTHEAD:

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 one 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.

My Canon PIXMA MP780 is not printing very well....it prints in stripes and very pale images show up (barely legible) even though there is enough ink. I think there might be something wrong with the ink...


This printer does not have an ink roller. The symptoms are that of a dirty or defective printhead. The printhead can be easily removed for cleaning or replacement. Start by removing all the ink tanks. Inside the tank frame, there are small handles you can grab to remove the printhead. It may require a little wiggling to get it out, but don't force it.

Once it's out, dampen a cotton swab with isopropyl alcohol and gently scrub the face. Reinstall the printhead and tanks, then test. If it still looks less than perfect but there is improvement, clean it again. It might take several tries to get it back to par.

If there is no improvement after a couple of cleanings, the printhead will need replacing. I've had pretty good luck finding replacements on eBay. They run around $40 for this make/model.

I also have no power on my Pixma 780, have check cords etc. How can I get the ink cartridges to move to the center to be removed with no power? Where is the print head and how is it removed?


The print head is where you put you inks, after removing inks you lift the gray handle and lift out the printhead. If you can't get the head out of the corner you will need to remove the right cover and unplug the gray cables from the circuit board. There are 3 to unplug,flat ribbons, toward the front or center of the circuit board.

Canon Pixma MP780 won't power on.


It could be that the printhead has gone bad, you need to remove the right side cover and unplug the front top two ribbon cables and try to power up again. When the printhead is locked on the right the only way to remove the printhead is to unplug it from the circuit board. Unplug again while the inks are in the center and remove the printhead. At this point you plug the cables back in and get a new printhead, plugging the bad one in again could ruin the main pcb.

I am trying to replace the printhead on the canon pixma 780 how do you get a new print head in the printer


You have to remove all the inks, and then there is a lever usually on the left that you lift straight up. The printhead has to lean forward from the top and then lift straight out. You install the new one bottom first then tilt back and lower the handle again. Install you inks and you're good to go. Sometimes one or two cleaning cycles to start all ink flowing properly.

You get that message when the printhead goes bad. It's not the ink cartridges. You need a new printhead

How do I remove printhead?


same as when you change ink tanks...
1.follow the same procedure you use to change ink tanks/cartridges to remove the current ink tanks
2.remove all ink tanks/cartridges
3.the printhead is what the ink tanks/cartridges sit in, the furthest half of the part the ink tanks/cartridges sit on is the removable part/printhead, it is loose so you can simply reach in and carefully pull it out.
Easy as 123 ...
