Because I forgot to mention that you shouldn't be doing that!
I cannot tell you how many times I've run into people unqualified trying to fix a problem that they don't fully understand... Just about everyone does it at one time or another in their life! Not long ago, I tried to work on my car a little bit, and ended up making the problem worse (lesson: don't attempt to fix car - ask someone who knows about cars to do it!).
But still, it is tempting isn't it? Today at work, I kept seeing people walk up to the printers and start pushing buttons, loading paper, and the notorious "resending the print job over and over again."
Since this is quite annoying, makes me look like a lazy computer lab assistant, and can easily lead to paper jams, I thought, "Why do people keep doing this, even though I rush over each time to fix the problems they have made?"
And then, it dawned on me as a student once again informed me that the "it's probably just that the color printer takes a while to warm up," (as I read which tray is the source of the paper jam)... People believe that they truly know the answer to these computer problems, but in reality, in their "attempt" to fix the computer, they make the problem ten times worse!
So, without being rude (and just telling them "ALWAYS ask the lab assistant") how do I communicate that same idea... The best way, is always the easiest... Make a simple 8.5x11 inch poster! "Document didn't print? Paper low? Blinking Lights? See your handy lab assistant for help!"
I posted, after approval of my boss, two of these posters (which were stylized a bit more than can be described in text form) - one at the set of black and white laser jet printers, and one by the solid-state color printer. Have a clear line of communication about policies and exactly what we would like the users to do is really the best way to keep the patrons of Support Services doing what we need them to do.
