Pixma MX892 - wrong operation with any color job after blackout, B/W only

[andylevi16]

Pixma MX892 - wrong operation with any color job after blackout, B/W only. Printhead test complete perfectly. It looks like single bit error in flash and need just re-flash FW but I already have the last version 6.20 and Cannon's update tool cannot re-flash the same version, only an older one. How to change FW version in my Pixma or use another way to reflash it

Hi andylevi16,

What version of Windows are you using?
If you are using a Mac, what version of OSX is installed?

Are you using your PIXMA MX892 wirelessly?
Or with a USB cable?

What is the exact wording of the error message that you get when you attempt to print?

Not any of that. for example of wrong printing attaching local color copy's scan here. Any B/W  printing and copies looks good
