Pro-10 Group 2 Printheads non-functional

I bought a new Pixma Pro-10 printer in March (about 8 months ago). It hasnt been used much, but it had been working fine.

 

I went to print something yesterday, and all the colors were way off. So I did a nozzle check. The group 1 nozzles were fine, but the group 2 nozzles column was completely blank. I did the prescribed clean-clean-deep clean-wait 24hrs-deep clean dance, but the group 2 nozzles were still dead.

 

I'll call Canon on Monday, and I'm going to go back to the store (which carries a lot of Canon stuff) and see if they know anything.

 

In the meantime, I was wondering if anyone here has experienced this. I hope I don't have to send it back, and end up having them send me a refurbished one.

 

Thanks!

The head is removeable/replaceable if it comes to that.. No need to send printer back if a clogged head is the problem.

 

If you have a Canon pigment printer you should print a nozzle check every two days. uses little ink and avoids triggering a cleaning cycle.

Re: Pro-10 Group 2 Printheads non-functional

Thanks jrhoffman75... nice to hear from a fellow New Englander.

 

I should have remembered that the heads on the Pro-10 were removable, since I think I installed them in the first place!

 

So I went to the store where I bought the printer, and the fellow there had a friend who had the same issue. The friend called Canon support who told him to remove all the ink cartridges, then the heads. Then replace everything.

 

When I did that, I at least got some things showing up in the group 2 column. After many many many many cleaning cycles, and having to replace all the group 2 ink cartridges (grumble), everything was just fine.

 

Of course, after all that, I found this; https://support.usa.canon.com/kb/index?page=content&id=ART164767&actp=search&viewlocale=en_US&search... which says to do the same thing. Oh well.

 

Hopefully this may help someone else who runs into this problem.

With "Then replace everything" do you mean put in a compleatly new print head, or just putting it in and out again?

 

Hope to get some answers, thanks.

I have tried taking it out and putting it in again but my black is still missing. Done multiple clean but still BK is not working. :-(
 
To clarify, I am printing out test prints and BK is missing and it is on a Pro-100.
 
Any suggestions? No more warranty unfortunately.

Hi HenrikE...

 

All I did was remove the ink cartridges, then the print heads, and just put them all back in. Nothing was replaced, the originals were put back in.

 

When I first had my problem, the entire group 2 column of the test print was completely blank. Not a pixel to be seen. After I removed/reinstalled everything, I saw some dots, but not many. But that was enough that repeated cleanings eventually cleared things up.

 

If _just_ your BK is missing, but all the other inks display properly on the test print, it might be your BK cartridge. The only thing I can think of is to remove and reinstall the BK cartridge. I think I may have done the remove/replace (all the cartridges and the print heads) thing a couple of times, trying to move things along.

 

Do things improve at all with successive cleanings? Did you try a deep cleaning? I think after I removed/replaced everything I just did normal cleanings, and each time a little bit more appeared on the test page. But I think I did have to repeat the remove/replace procedure at some point because the improvement had stopped. They resumed after I did the remove/replace again.

 

Also, I'm on a Pro-10 not Pro-100, and I don't know what the differences are or if they'd make any difference.

 

Hope this helps... good luck!

Thank You Eric!

 

I did not do the trick for me, at least with the number of deep clean I felt ok to waste ink on. BUT, dipping the ink heads in a few mm of window cleaner and push some from the top did! Very quick fix!

 

Let me know if anyone needs more description of the process.
