Who says girls can't fix things?

Our printer at work broke today. Before I could understand the problem, the girls had ripped open the machine and started taking pieces out, washing them and fussing with the parts. I had no idea if they had done this before or knew what they were doing, and when I asked they assured me that they would call someone. Would: future tense. They hadn't yet actually consulted a technician who could identify the problem and talk them through the solution process. After they had removed half the printer guts, a phone call was made. Fortunately, following the reinstallation of all the parts, the printer still worked! Unfortunately, the problem was not fixed and every document continues to print with a 1/4 inch vertical line at the left of each page. At least they didn't make it worse!
