PIXMA G6020 Prints in Black Only

[ccnbigd]

I'm having the same problem, but without a 5200 error. My PIXMA G6020 was printing just fine.

Now it acts as if it were a "black ink only" printer. The diagnostic prints from ALL maintenance routines
(head alignment, cleaning, deep cleaning, etc.) show only black ink results, as if the color print heads don't even exist!
The diagnostic print outs *** used to *** show results in black, yellow, cyan, and magenta... now only black.

When performing a color copy from the printer's scan platter, it prints in black ink only, printing the image in grayscale,
as if I had black copy button. When I print a color image from my Windows 10 laptop using Photoshop,
the printout shows only the parts of the picture where the black ink head was used. The color portions of the image are missing
from the printout completely. When I printed the same color image with the "grayscale printing" option checked
in the advanced print settings dialog, the entire image printed, but in grayscale only
(i.e. a black and white picture...as if I printed a color image to a printer that only prints in black ink).

Since the problem appeared suddenly, and similar behavior occurs from the printer itself and print jobs spooled from
a computer, it seems like this could be a firmware issue. I vaguely remember doing a firmware update
(this was week's ago), but I don't remember. Will post a reply once I get this figured out.

I am having exactly the same issues.

The printer worked for a little while after purchase, but now behaves as if it is a black-and-white only printer.  And, yes, I have the latest firmware installed.

So much for trying to buy a higher-end printer model for better performance...

For what it's worth, I resolved this problem myself. I had to do the deep clean function (for color only, black was working fine), twice, before I finally saw some color show up. I'm very leery of using clean, deep clean, or ink flush due to the issues about when the "diaper" fills up, the printer is then useless. But for whatever reason, apparently the ink dump was needed to get the color going. Not a great initial customer experience for sure, and there was really no warning about that in the user manual setup instructions that this might be needed.

Thank you for the information!  As soon as I tried to run a deep cleaning, the printer popped up "Error 5200".  To clear that error, the manual said I had to do an ink flush...which used an insane amount of ink (1/4 tank of each color!! 😱).  However, I have finally regained color printing capacity!

Now I just hope it stays fixed...

Well, ran through all the posted fixes, never got an error, and confirming since the firmware update I have a an expensive black /grayscale printer.  Guess I will pop back here when I have time to chat with Tech support to see what questions they have, and what they wouldn't post here while customers try and diagnose and possibly fix their product.
