Tip
Shares some advice on avoiding printer jams, “It has to do not only with the finish on one side of the paper, but the ‘curl’ of the paper. Hold an unpackaged ream by one end in your hand, and you’ll see that it curls down more easily with one side up than it does with the other side up. The paper should be loaded into the tray with the more easily curling side facing down.” And adds, “This becomes extremity important in the large high-speed printers and copiers that the whole office uses. It’s not as big of a deal in the slower desktop printers, although putting the paper in the right way helps reduce jams somewhat in them too. And it helps with the paper curl.”
Some helpful advice, “Don’t take canned air to a running projector. The bulbs get so hot that it can cause a dust fire when the dust becomes un-settled… Just caused a flash fire and horrible smell in front of a classroom of 32 fifth graders. They enjoyed it, the teacher and I did not… [and] the projector doesn’t work anymore.”
