Samsung C460FW Toner

Win 7 PC shows status of toner.
Yellow has triggered a warning message since it and only it has gone
below 10% remaining. Yellow shows 9%. Others are much higher
percentage available.

All cartridges are Samsung brand.

However, I cannot get the printer to print anything.
It keeps flashing the toner low message and not allowing me to print.

I did take out and shake the yellow toner and restarted several times
but no luck clearing the problem to allow me to print.

Suggestion please.

Thanks !

Methinks you can disable the toner low warning "feature" with the well
hidden "tech menu":
"Samsung Xpress C460W hidden menus & reset those warnings"

Or, maybe try this:

Obviously, buy new toner.
Ever wonder where the yellow ink and toner goes?
Every page you print uses yellow to print all the
information it has about who and where you are.
And no, it won't print if it can't rat you out.

Well, lets see if that works as you claim. Every page is marked with
up to a maximum of 512 dots. Most MIC codes are less than half of the
512 dots, but I'll use the maximum number for this exercise. Each dot
is 0.1mm in diameter or 0.05mm radius. Therefore, the maximum
coverage in yellow toner is:
Pi * r^2 * number_of_dots = Total_area
3.14 * 0.05^2 * 512 = 4 sq-mm
If all the 512 dots were arranged in a non-overlapping staggered grid
pattern, that would produce a 2mm x 2mm yellow square. That's a
really tiny area which would hardly affect yellow toner consumption.

Oops. I forgot to multiply by the number of times the pattern is
repeated on a page.

My count is 120 times for letter size paper. That would cover 480
sq-mm or 22mm x 22mm square (0.87 x 0.87 inches) maximum (if every
possible dot in the pattern was printed). That's much more toner
consumption than I originally estimated and would consume more yellow
toner than the other colors (except maybe black).

I recently inherited from a customer an HP LaserJet Pro m477fnw color
laser printer:
<https://www.amazon.com/HP-Color-LaserJet-M477fnw-Renewed/dp/B01N5XP9TL/>
Quite good, but this particular model doesn't do double sided
printing. When I picked up the printer, the yellow toner level was
well below the other colors. The dots are visible with a microscope
and UV illumination.

Grumble...

The encoding seems to be different for different manufacturers. After
