I'm running Mac OS Mojave 10.14.5 but the Operating System drop down menu on this forum doesn't include that!
I cannot print from Tray 1 in any app using the autoselect function. If I select Tray 1 it prints from Tray 1; so what's the problem you may ask?
If I go to the printer itself and try to print, for example, a configuration report, I get an error code saying the bypass tray is empty. I have checked thre paper tray settings and Tray 1 is set to autoselect, the bypass tray is not - becasue you can not auto select it.
So why can't I print anything on the printer itself unless I put paper in the bypass tray?
