Go to this article and at step 2 it explains how to configure that print driver with the correct number of trays.
I have buyed a Versalink C8000 Printer and aditional the 3. and 4. Trays (2x520 paper). So i have 4 Trays for paper.
In the Touchscreen monitor i have configured all 4 Trays. All is ok.
In the Webserver are only 3 Trays visible.
In the Windows 10 Printer Driver PS only 2 Trays. The tray 3 and 4 not visible and i don´t now how can i choose it.
The driver is installed with the actaully xeroxsmartstart tool. Please see fotos below.
Thanks for your help.
