The following example should illustrate the problem:
- Load A4 paper in Tray 1, Tray 2, and Tray 3.
- Set Tray 1 to Letterhead, Tray 2 to Card Stock, and Tray 3 to Plain Paper.
- Make sure the General Defaults are set to International.
- Reboot the MFP.
- Now place a sheet of A4 paper in the ADF and press COPY. The copy should print on plain A4 paper from Tray 3. However, the printer posts the message Change Tray 2 Plain A4.
