Issue Description:
Issue is seen when the printer is in Safe Mode or Safe Mode is enabled.
In the printer’s web page, when changing the tray configuration settings, Tray 1 or other paper sources (Tray 2, Tray 3, etc.) is not found in the list.

Solution:

Check the printer’s status to know whether Safe Mode is enabled.

Disable Safe Mode by following either of these steps below:
On the printer's control panel, touch Settings > Device > Maintenance > Configuration Menu > Device Operations > Safe Mode > Off.
Access the printer’s web page by typing its IP address on a browser, then navigate through Settings > Device > Maintenance > Configuration Menu > Device Operations, then uncheck Safe Mode and click Save to submit the changes.
Note:Printer will reboot by itself once you click on Save.

Once printer is back on Ready, check the tray configuration settings to know whether the Tray 1 selection is now available. Go to Settings, select Paper and then under Tray Configuration you should see Tray 1 from the Source list.
