"Hello? My printer won't print!"
PLACE - The support desk ...
TIME - During first cup of coffee ...

"Information Systems, can I help you?"
"Yeah, my printer won't print! It's making strange noises and the paper keeps getting stuck."
"Okay, we'll be right over."
We make a visit the user who, sure enough, has a three-month old HP DeskJet 5550 that's making very strange noises. It prints about half a page and then jams up with a blinking paper feed error light.
"Well, it's been doing this for about a week now. I've tried turning the printer off and on, turning the PC off and on ... doesn't seem to get any better."
Well ... no kidding! :devil:
Remove existing printer, replace with identical printer from stock. Take malfunctioning printer back to shop. Quick inspection reveals that a small plastic tab on the paper feed tray is missing. We figure that if we can find this missing piece of plastic we'll have our problem solved.
Several hours later we have the printer in several pieces and can't find anything obviously amiss. Sometimes it'll feed the paper OK, most of the time it makes strange noises and jams.
I finally tell my partner that unless he has any bright ideas that we'd better just part it out, save the parts that can be re-used and junk the chassis.
About a half-hour later he comes out of the shop chuckling. Says to me, "You're going to have to come see this to believe it!"
He points 'way to the back of the printer where I can just see a tiny little corner of something sticking out of the printer. I turn it around and get a look from another angle ... it's one of those faux business cards, plastic on the front with a magnetic backing on it. It's stuck to the paper feed rollers. Apparently sometimes it'll fall off and let the paper feed but eventually the magnet on the back and the vibration bring the card back into contact with the metal roller bar ... and wham! the paper jams between the business card and the chassis of the printer.
A couple minutes careful work with a pair of needle-nose pliers extracts the card intact, with only some scratches and a few ink smears to show where it's been. We re-assemble the printer, run some tests ... looks OK now, so back on the shelf it goes.
(By the way, we never did find that missing piece of plastic. <sigh>)
We take the business card back to the customer ...
"Hmmm ... I wondered where I'd lost that. Thanks!"
:rolleyes:
