PIXMA MG7520 not printing files from computer

[snooks10]

I have a Pixma MG7520 printer which will print all internally generated test patterns without a problem, but when I send a text (or any type of) file from any of my computers it barely prints any of the file content.  It almost seems like a print buffer problem where the data is not getting through.

Any ideas or suggestions on how to troubleshoot and/or fix?

Thanks.

Hi snooks10,

Please load plain paper into your printer and then print a test page from your PIXMA MG7520 following these steps:

1.  Please swipe the HOME screen and then tap the wrench and screwdriver icon on the display of your PIXMA MG7520.

2.  Tap Maintenance.

3.  Tap Print nozzle check pattern.

4.  Tap Yes.

Please take a picture of the page that prints and then please attach that image to your reply of this post.

Hi Patrick,

Thank you for your reply.

I finally got a few minutes to do what you asked and a couple of other things that might help.

I have attached a photo of the print nozzle check pattern as suggest, but I went a little further and scanned that image into my desktop and then printed it successfully.  (In the picture the original is on the top and the scanned/printed copy is on the bottom.)

I then tried to print a page from a web browser (MS Edge), and that also printed ok. (2nd photo)

I then tried to print a MS Word (.docx) and all that came out was a blank page.  I converted that file to a .pdf file printed it and that also came out blank.  Same thing happened when I copied/pasted the text of the Word doc into Notepad.

I then tried to copy a text document I had laying around and that also came out blank.

Knowing that the CLI-251 BK XL cartridge was running low, I replaced it to see if it was really empty and just not being read correctly, but the new cartridge did not change the printing behavior.

  

 Thanks again for your attention to this.

Hi snooks10,

When performing the type of printing that you are, the PGBK ink tank will print black.

PGBK does not appear on the nozzle check that you provided, which would be the cause of this issue.

To resolve this issue, please follow all of the steps provided on this page from the manual:

MG7500 series > Overview of the Printer > Maintenance > Maintenance Procedure
