yes, they changed that to prevent printing on other type of paper
what you should do , place paper in tray 5, specify setting like type, format , color ....
then in fiery driver , choose tray 5 , paper type, size = auto selet OR the same setting you setup on the machine
that way you dont have a mismatch between driver and machine
The client is used to the way the 250 and then put the paper in the printer driver to specify and imagine it now .. you know how it is changing the mechanism is very complicated.
There is no way in the paper and put 550 in the app specify the size, type, weight .. and take the 550 paper without putting it back on display?
As he did in the 250;)
There must be a tab in the options .. Say yes please:)
