About a week ago I got a call at an account that was having a issue when they printed where an extra blank page was being output at the end of the job, but only intermittently.
They told me that the issue normally came up when printing from Oracle. (That was the reason I got the call, as I'm an analyst these days, and not a tech. However I did spend 17 years being one before being granted my beanie and propeller...)
While I was getting all set to do a data capture and start working with IT, I figured I'd check the basics first. Sure 'nuff, there was some terribly cut, nasty, wavy paper in the cassettes. To make matters worse, a lot of it was already printed on, and they told me that they like to save paper. To add insult to injury, it was in a shipping department in a factory, which had open windows and outside doors. For all intents and purposes, the machine is outside.
Then came the coup de gras, "It worked fine in our old machine. There must be something wrong with yours. Fix it!!"
Turns out that the new Ricoh color MFP we put in replaced an older HP LaserJet printer, which can run basically anything. If they had been copying, they would have seen the problem there as well, but they only print.
Once they put new paper in the machine (I don't know what brand), all worked well.
Arrrgggg......
