PIXMA MP780 printing trouble

I just installed a new 3eBK cartridge and experienced some minor printing problems. Initially the print pattern showed a blank space approx. 2mm wide throught the middle of the print pattern. That was yesterday. Today, the 3eBK cartridge is putting no ink on the paper. The print pattern shows all cartridges are printing normal except there is no 3eBK pattern printed! I have confirmed the new cartridge is not dry.

What can I do to get my black ink printing again?

Thanks,

    Hi,

    May 29th- I too have a similar problem with no black ink showing up at all when i print. I have executed all the nozzle checks, cleaning, deep cleaning and each time the pattern showed all the colors but nothing for 3eblack. I then put in a new cartridge for the 3eblack and and did the cleaning and the nozzle cleaning again and now I have no yellow and no black 3e ink showing up.

    Any suggestions as to what to do?

    Thanks

    Katy

If you haven't done so, I would try another new cartridge. It is entirely possible (and occurs frequently) that you got a bad cartridge. Assuming you removed the tape from the cartridge before putting it in, this is generally indicative of either a bad cartridge, bad print head, or that heads or ink tanks may need cleaning.

The Canon support page for this printer is at:
http://www.usa.canon.com/consumer/controller?act=ModelInfoAct&tabact=SupportDetailTabAct&fcategoryid=238&modelid=10444

However, as Canon pages come up as generic pages (without the text I input for you), you will have to type in "missing black ink" (without quotes), to see the material they have posted in this regard. You will find instructions there in regard to how to clean the print heads, etc., if that is necessary. However, I would definitely try another cartridge first, especially if you haven't had that much use on the printer, such that you think these other measures may be necessary.

Please post back if you need further help, otherwise thanks for rating FixYa!

My MP780 is about 2.5 yrs old and has not been heavily used. I got a message saying 3 ink tanks were empty, including 3eBK (the other 2 tanks had been replaced a few weeks ago). After inserting 3 new tanks, the result was that the first few lines would come out OK and the following lines would get weaker and weaker. I emailed Canon and got some advice, including "deep cleaning" (if that is not the same as the "cleaning" on the menu, how do you do it?). The advice failed to help. When I reported this, I was advised either to go to an Authorized Service Facility, or to buy a new unit (at a discount). This seemed absurd, so I went on line and found, on fixya, advice to simply try a new tank. I put back the old 3eBK and now the printer works fine! Thank you fixya!

Main black print(BCI-3eBK)seems clogged and nozzle check shows only partial pattern. The cartridge seemed to be stuck to the print head. This happened before about two months ago. My technician cleaned it....


Sounds like you need a new printhead, and the only thing you need for cleaning is a damp cloth. All the Canon inks are water soluable. The printheads don't clean very well and don't last long if you do clean them.

The tank 3eBK black do not print


olofossonbygg,
Looks to me like an air lock in the system.

Have you just changed the black cartridge because of an error message and did it print up to the point where you just changed it?
Just replacing the cartridge with a new on can sometimes lead to an air lock in the small ink feed system.
Does your cartridge have the writing head at the bottom or is it just an ink tank, in which case it could defiantly be an air lock.
Try a cleaning cycle, and leave the printer for a few hours to stand and let the air lock escape naturally. Running loads of cleaning cycles will use a lot of ink, so don't be too hasty.

3eBk will not print. Canon MP780


Replacing the printhead may work, but it could be a problem with the cleaning assembly. Take out the 3ebk and run a cleaning, if the ink goes away on the pad where the ink cart. goes, then clean assy. is OK, and you need a new printhead.

The printhead is plugged or burned out for the 3EBK. You need a new printhead, QY6-0049-000, around $40.00.

Black ink 3eBk wont print


Ok what you need to do is make sure that the ink cartridge is properly inserted all the way. If it's not then you won't be able to print out black ink at all.

Canon ip4000r doesn't print 3ebk (black)


First of all... have you tampered with the printer's firmware? If not, it's unlikely it became corrupted. But if replacing the ink cartridges with fresh ones, and using a new print head did not fix your problem, you may be out of luck.

Is this a new problem, or has it always been like this?

Could it be that the print driver is always printing photo? In that case, it uses the narrow black ink cartridge instead of the fat 3eBK cart. You should print a nozzle check pattern and verify that you see the 3eBK cartridge pattern. If you do, the problem is likely SOFTWARE... your driver settings, not the printer itself.

I hope this helps.

I can't print ordinary black text any more


In fact, I ran a couple more ordinary cleaning sequences with a new cartridge in place, and it prints normally now. The only anomaly is that the ink-level panel still shows the 3eBK as being half-full (which is the level it showed when I discarded the previous cartridge).

Ink Tank not showing up


That's a BCI-3eBK cartridge. Most Canon inkjet problems can be resolved by replacing the print head. eBay is the best place to find a replacement.

Canon pixma mp780 - vertical line on printing


Not sure if this will help but there is a small glass panel to the left of your flatbed scanner- this must be clean or else I get a black vertical line in my printing.
