HP OfficeJet 4650 Printer is only printing in black and white ink, although diagnostic in color

HP Officejet 4650 is only printing in black and white except for only the Print Quality Diagnostic Page prints in color. Talked to Instant Ink on chat and that doesn't seem to be the problem with the cartridges they are full of ink and also because it will print off in color ink and black ink as appropriate when I made a copy of a brochure when I placed it on the scanner glass. I have checked the HP Printer Assistant, HP Print and Scan Dr., HP Smart, and Windows 10 settings for Printer and Scanner devices. I don't have a warranty any longer since this printer I have had for several years and it has worked pretty good. All is set for color that I know of! It seems that all my software and drivers is up to date. Could anyone have any idea how to fix this recent problem?

Having the same problem !  Uninstalled, re-installed printer. There is a 'Color Management' tab in the printer settings - but that is generally related to monitors...no idea why that is now on the printer.  Crazy.!

PortOCar, I wondered about that too but it seemed to not be helpful. I looked high and low and felt that somewhere I must had changed settings to black ink only, but where? I checked everything to the best of my knowledge. You are the only one who has replied to my question and I thank you, but how do I get someone who is knowledgeable to answer?
