A jogger is usually the first step in paper handling because it removes static electricity and un-sticks paper before the stack is processed in a folder, folder-inserter, copier, printing press, etc. The benefits of removing static electricity and separating sheets are more efficient paper processing and the prevention of paper jams. The Martin Yale 4200 is a very popular paper jogger for a variety of reasons. We've received feedback that this model is preferable to the Martin Yale 400 because of its open design. The fact that it only has three walls instead of four makes loading and unloading paper much easier. This 4200 is also much larger than the 400, with a tray that is easy to tilt to accommodate a greater variety of paper sizes. To be specific, the Martin Yale 4200 handles a capacity of 17" x 22" x 3" inches. Place your stack of paper into the jogger, press the power button located on the back of the jogger, and watch as your paper becomes precisely aligned and static free. The 4200's variable speed control ensures that you will be able to jog your paper properly regardless of paper weight or quantity. Its heavy gauge steel construction makes the Martin Yale 4200 extremely durable. Although heavy-duty in design, the 4200 weighs only 50 lbs. and can thus be easily relocated around the office. With a high sheet capacity and easy operation, the Martin Yale 4200 paper jogger is the choice machine for print shops and copy centers.
