I can understand Bosse's comment. Here we got rid of 'normal' fax machines ages ago. The combo device scans and emails the document rather than doing it the old way. So it's up to the other end if they want to print it, and if they recieve a blank document they still know where it came from to chase it up too... Digital copies are so much easier to file as well.
But I'm from Australia, so we probably do some things a little differently..
All of you like Asst.Evnt who offer advice on how fax machines work. We are aware of the fact that fax machine examples that the printed side goes face up is painfully obvious. I wonder, though, do you people analyze every joke? I would like to see you at a comedy club doing that as part of the audience. Scott Adams may rightly assume that many employees are clueless, and those of us who have gravitated away from corporate stupidity and are now either self-employed or luckily CEO's have been "enlightened." Adams may also think that CEO's are in the same boat as thier employees.
Whether your fax machine goes blank side up or not, they all have that symbol of the piece of paper with lines on one side, the other side blank, and the corner folded over to see which side goes up. This is just a case of lousy admin. This is probably the same admin who puts the paper in the copier upside down so the auto-stapler does the wrong corner.
