HELP PLEASE! blurry BLACK text printing PIXMA MG7120

[JIMBENDER]

My Pixma MG7120 Printer is printing all black text in blurry fashion.  I have cleaned in every way and even replaced the black ink.  Not sure what I am doing wrong or how to fix.

I just wanted to add that I followed the original instructions by Canon Support and it worked for me right away.

This also worked on a PIxma 4250. I do little printing, but when I do it needs to look good. This made a huge difference, Thank you.

We have two identical MG5750 printers, one working badly and the other working well. I tried swapping the heads to see where the cause of the problem is, whether the head or the printer. Well, I shouldn't have done that! Because I transferred the same problem to the second head. Now they are both working badly. Even after returning the heads to the original printers. I don't understand it, I only printed one single test page and good head broke down. I am adding my experience here because no one has tried something like this. Maybe someone will find a solution.

That might work, however, I'm done with canon printers.  I've used them for almost 20 years, but always have to replace them every 3 years.  I switched to an epson ecotank with photo black and have never looked back.  They have a swapable ink waste tank and can print up to 13x19.  the images look almost as good as my canon pro 9000 with 8 inks, but that ink is so expensive, i don't use the printer as often.  so switch to the Epson ET-8550  13x19 or et 8500   8.5x11

Where do you change the paper setting to Photo Matte?

It may be different in your printer, but for mine I go into 'Printer Settings', then in the Printer Settings window I change Media Type to 'Matte Photo Paper', then Print Quality to 'High'.  If you leave the Media Type as 'Standard', you don't get the High option in Print Quality.

I have 2 MG5750. The first one stopped functioning a year ago. It looked like the nozzles were clogged. I've had this with other Canon printers in the past, but with this one I couldn't fix it. Luckily I had the 2nd one, but that started to print every black texts double. I found this community and also this work-around, which helps indeed. But it isn't a solution like others already mention. Not only does it require more ink and does it take a lot more time to print, for me the biggest issue with the work-around is that it's no longer possible to use the double sided printing option. Because I started to be really annoyed with being forced to replace Canon printers every few years because of problems, I decided to buy an Epson Workforce WF-2840DWF. But I have to admit that I missed my Canon from day 1. The Canon can auto shutdown, but wake up automatically too, which I find great. The Epson has to be powered on by hand every time I want to use it. But the worst part is that it hasn't worked like it should from day 1. I guess there's a problem with the paperfeed mechanism, which makes use of the ADF impossible. Also double sided printing is impossible. After struggling for 6 months I decided to send it back for a repair and yesterday I reinstalled the MG5750. Again: I think everything about this thing is superior to the Epson (even assuming that the Epson didn't have a problem), but it's a shame that Canon doesn't want printers to last longer than a couple of years.

My Pixma MG6851 has started doing this blurry black text thing every few lines of print. I have cleaned the strip, but it still does it. Might it be the paper surface being too slippy?

Just tried different paper. Same thing.

Does it still print blurry if the print quality is set to 'high'?
