MAXIFY GX7050 keeps printing black & white instead colors

[Emanresu]

For unknown reason, my printer GX7000 series won't print in colors anymore even I clearly still have the blue, yellow and pink ink about 3/4, it just only print black & white no matter if I print from computers, smartphones or photo copy (I did pressed GREEN button). I haven't touched any settings since a year ago. I have tried to reset everything to default, it's still printing black & white

Is it the firmware problem? The firmware version is 1.130

Run a nozzle check.

Canon : Inkjet Manuals : GX7000 series : Printing the Nozzle Check Pattern

[Emanresu]

Ran nozzle check. I'm only getting BK pattern on the paper, no C, M and Y pattern as mentioned on the manuals. Is it a sign the firmware is broken?

[jrhoffman75]

It is more likely a clogged print head; firmware doesn’t break. 

Run a nozzle cleaning and see if that cures it.

Yead I did cleaning 3 times, also ran deep cleaning then ran nozzle check and test page from service mode. I posted the image of the tests below

My guess then would be a failed print head or a component failure. Need to contact Canon service.

Ok thanks

Also ran test page from service mode, also no colors
