Question about Canon PIXMA MP760 All-In-One InkJet Printer

1 Answer

Our Mp760 just decided it would stop printing. It will still run as if printing but there is no ink. We changed the ink cartridges and still no luck. A few of the items on the page print if they are color but only in the color cartridges and not the black. I have tried to run test copies, do cleaning, and do deep cleaning but nothing has worked as of yet.

Are you using OEM cartridges or aftermarket/reloaded cartridges. Your problem sounds like the nozzles are clogged and need to be deep cleaned. To perform this you need to put in new OEM cartridges and run the deep cleaning (at least 3x) and the alignment utility. This should clear the clogged nozzles.
Aftermarket/refilled cartridges do not always meet the manufacturer's specifications for quality. If you want to try a good source for aftermarket cartridges, try cartridges from LDproducts.com for your printer. I've never had a problem with their aftermarket cartridges.
Please rate this solution. Thanks.

My Canon pixma mp760 wont print in black. colour printing is ok


Possible that the B&W ink cartridge is faulty or there is poor installation . You need to shut down the printer and remove the ink cartridge. now reinstall after ensuring that printer was disconnected and then connected.

Nozzle test does not show pattern for either BLACK output; deep clean does not correct problem. both catridges have plenty ink. color displays are ok.


CANON MP780 BLACK DOES NOT PRINT

This is what works for me. Try at your own risk. I cleaned 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 **** 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.

Have Pixma MP760. Problem with magenta print nozzle, which is not functioning properly. All others functioning fine. Repeated cleaning has improved the print colour but still patchy on the nozzle check...


Are you using aftermarket/refilled cartridges? To do a complete cleaning of the nozzle, you need to use a new OEM ink cartridge. Run the deep cleaning at least 3 times. This will clear the nozzle. You will eventually have the same problem with the other nozzles as long as you continue to use aftermarket/refilled cartridges. The inks used in them are not as highly quality controlled as the OEM inks so you will end up with clogged or partially clogged nozzles. The new OEM cartridges method usually clears the problem.
Let me know if this clears the problem. Thanks.

My MP760 just stopped printing all colors except 3eBK. Made nice color prints two days ago. No warns or messages.


I'm not sure if you have solved this or not but try replacing the printhead. I had a similar problem with my MP760 and the IT guy for my office suggested I do this and it worked!

Printing in yellow tones, all ink cartridges are full and grid pattern ok and nozzles cleaned


Possibly the print head is getting plugged or the color map settings are changed. Try removing the printer and reinstalling the drivers as well as clicking the "default" settings button after. If this does not fix it, possibly the head itself is ok on a test pattern with low ink but on printing is not delivering full ink in all colors, only yellow, indicating the head is plugging. Possibly cleaning with alcohol would help, place a drop on each place the cartridge inserts on the ink tubes and also clean the head surface where the ink comes out with a Q-tip and alcohol and then do a regular head clean.

Grid pattern on Canon MP760 test print is patchy and cleaning process does not fix it.


You can try to remove the print head and ink cartridges.
Soak the head in an ammonia10-20% solution with warm water for 30-45 min.
Dry the head completely and re-install.Now run your grid patter,
It sonds like(from the grid reference)that only the black is clogging.This is a pigmented ink and tend to dry if not used for months at a time.

Changed the print head in my Canon MP760 but now printing is blurred and very faint


Try cleaning the felt pads where the print head would rest when not printing. They get full of ink and cause more printing problems. I use water to clean them.Don't loose them, they are needed to keep the print head from drying out.
