mg 7520 not printing black

[tcornellas]

Hi! - I'm trying to print a file that contains only black text/graphics- but it prints in blue instead... New black cartridges. no stickers covering nozzles, all are in the correct spaces in the printer. I ran the nozzle tests and it prints fine for the tests, but not for the actual document. 

I took out all new cartridges and put them back in, I have done all cleanings available on the printer- and it continues to do the same thing.

I've tried printing as a "photo" and was horrible, printed SOME black but mainly blue. 

I've had the printer for 2 1/2 years and would really like to keep it going longer. 
Please advise. Thank you!

Hi tcornellas,

In order to better assist you, allow me to ask a couple questions:

• Are you able to print black from other programs?
• Are you using grayscale printing?
• Which version of Windows or Macintosh are you using?

I look forward to your reply.

hello,

I have the mg7520 and changed all the ink cartridges with new ones and still, the test page is not printing properly.

Is there any kind of maintenance I can do to get rid of this issue?

I am using Mac to wirelessly print pdfs.

The PGBK part of my nozzle check pattern is not printing at all. I have replaced all ink cartridges, cleaned, deep cleaned twice with a 24-hour wait time in between deep cleans as recommended. What else should I try?

RESOLVED:: - It wound up being a faulty ink cartridge. even though the ink cartridge was new, something was faulty with it... Iam not sure if it was the sensor on it or what- but by changing out that ink cartridge, it was resolved. 🙂
