Our 5550 printers will tell us when they are 100% out of paper. the new B610s will say when a tray is empty but not the the printer is 100% out of paper. on Centreware it just shows a tray empty and says we can still print. on The alart settings on the printer, there is nothing to turn on about the printer being out of paper. It should work the same as if it was out of toner. How do we fix this?
