Henning - Just as a matter of interest, and for clarification, what language
is the control panel display set to ? I , being English speaking, am not
familiar with the word ZUF.
As previously mentioned on this thread, I think the printer was asking the
manual tray to put in an A4 sheet.
What you perhaps need to do is go into the printing menu and select mp tray =
off, then the config menu and manual = off. it will then (i think) look for the
pc tray or lower tray first.
let me know how you get on
