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 !
