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

Black will not print

In the middle of printing a large document my printer ran out of the 3e black ink cartridge. I replaced it, but when I went to resume printing only gray and the colors printed - no black. I went and bought another new 3e cartridge and replace the other. Yet, still NO black will print. Every other color and every other feature is functioning fine. HELP!!!!

This may seem obvious but have you tried cleaning and refreshing the print heads? I've had a similar problem with only certain colors and the cleaning seemed to help.

Override empty ink tank on Canon PIXMA MX860


The title of this topic is for the MX860. It has no "RESUME" button, so the advice submitted by cene765 does not work. But there is a solution.

The MX860 has two black ink cartridges--one small (like the colored ones) and one large. So, you will run out of colored ink way before you run out of black. I found that by selecting the "Gray scale" printing option, I could still print with color cartridges being very low. Even when the printer told me that the color cartridges were empty, I could still print by clicking the "OK" button. However, this does not last. Eventually, the printer will flag the color cartridges with an alarm. When that happens, the printer stops working, freezing at the alarm until you replace the cartridge.

However, you can still print. What you need to do is press and hold the STOP button for a few moments. The alarm will be released and then you let go of the button. Printing can resume. This happened to me where the alarm was triggered by the cyan cartridge, before I could even try to print. When I used the STOP button bypass, printing started but was then flagged by the magenta cartridge. I thought for sure that pressing STOP while in the middle of starting the print cycle would abort it, but thankfully it did not--the alarm was cleared and printing resumed.

Many printers require you to print a test page and go through a process to align the new cartridge. If you haven't done this I would suggest this as your first step. This will confirm if the printer is working.

If still no joy, disconnect printer from computer, uninstall it then reinstall it. Can often save hours of messing using this method.

IP4000 - How can I force the printer to use the large black (6) ink cartridge?


Do you mean the large black ink as in the 3e vs. the 6? If so, the large black, 3e, is a pigment based ink and the printer should only use it when print text and black and white things. The 6 black is a dye based ink and the printer should only use it when printing photos.

Not printing after color cartridge ran out - new black cartridge installed.


Yes, this printer has fixed printheads and must have ink in each color to prevent damage to the printheads. Even when printing black only each color is spit in the servicing area to keep the printhead unclogged.

3e Black cartridge won't print


I'm not an expert but I go through a lot of ink.. I have found that even with new ink some of the tanks of ink aren't any good especially with compatible which i buy a lot of because it's a lot cheaper (ebay). With that ink I have gone through 10 cartridges in a row before finding one that worked correctly again (I mean out of 100+ cartridges hitting a run of 10 that where bad but the rest good.)

Also, a tech for epson once told me to hit deep clean 7 times in a row before a head check to clean their nozzles.. That has helped with my printer and at Fry's electronics, they have a cleaning solvent in kit, haven't tried it, but i have run alcohol through mine but I'm told that is very ******* the print head (dissolves the glue).

Hope that helped..

Thanks for getting back to me.
Sorry this ain't a solution but it seems to be the only cash-free way to contact you. No problem not solved - though I have tried everything. Dismantled the printer; washed, dried and replaced the waste ink pads; washed the print head; blew compressed air through the print-head sponge; replaced the cartridge 3 times; printed hundreds of test prints. I can't think of anything else to do and so I think the only solution is to replace the printhead (probably not even available) or replace the printer. The latter is looking most likely.

Replaced empt 3E cartridge. Now it won't print


Kind of an X-file situation there. You should try an other cartridge, maybe that one is defective
