Color document prints in shades of red, despite setting is grayscale [ Edited ]

HP 6310 All In One

I have a color document. The setting for HP is grayscale.

When I print, anything which is in color prints in varying shades of red

The black letters print black, which is what I want

Generally graphics are printed with the color cartridge, even if printing in grayscale.  Look for a setting "Use black ink only".  As for the red print,  likely your cyan ink is running low.

took a while to find where to set the 'black ink only' but i HOPE my docs will no longer print in color despite setting to 'grayscale only' - how stupid to ignore that!.....
