Printer is a Brother HL 22700-W. The toner light was on and I reset the printer to allow me to print additional pages. However, whenever I now print, which I'm able to do, there's a tiny yellow triangle on the printer icon in the dock. Otherwise, the printer operates normally.
I checked the Options and Supplies in the Printer window in System Preferences and I'm told the printer cover is open (and that the toner is low). I opened and closed the the cover, but the warning remains on. And, as I said, the printer prints.
Rebooted, but the warning and the yellow triangle remain. How can I eliminate both?
