Hi Lieselot,
it looks like you are using different device-types. Have a look at the pdf itself I would suggest that there is another pageformat in. This could happen while generating the pdf.
The output-type itself doesn't have any cards in.
The device-type/printer is the one you should have a look at.
Another thought is the permission. MAybe your faxservice isn't allowed after converting to use the hard-disk. Mhh.. tricky
