Tray 2 not recognizing paper always shows empty

[Tootalluk]

The printer will not recognize and paper in tray 2 i have tried with different levels of paper but always shows as empty i am using standard A4 paper 

no matter what i try it will not see the paper in the tray

[PSSG]

Just to be clear, the printer's control panel is indicating that tray 2 is empty?  Or, is paper error on your desktop?  If error is on your desktop, how is printer connected to desktop?

whether I try to print from desktop or phone I get message "tray empty or open"   It is not empty or open. I've changed paper, checked drawer with no results

Did you have any recent paper jams that preceded this tray empty issue? I have seen cases where a jam prevents proper operation of flags in the paper path. The best way to check is to power off the printer, remove all the toner cartridges (set on soft surface and cover them to prevent light damage to drums) and remove the paper tray. Drop the duplex/tray 1 insert by pressing the green lever inside the paper tray cavity. Then carefully tilt the printer over onto one side and examine the bottom of the printer, looking for any bits  of paper.
