We PDF pretty well everything but every now and then we need to print a hard copy of a one-pager that we would like to print on manual feed.
I've done further testing and I'm having the same problem with another printer as well (HP4350 and Minolta Bizhub C353). The manual feed works if I select it from the preview screen though...
There is a work around to get the manual feed to function but I think the Setup button | Manual Feed option should also work.
