For the sake of stability, we recommend that you choose a table/work surface that is rated for 500lbs to place the 4200 on. Let's take a look at the 4200's strengths and weaknesses. This makes the 4200 a great choice for production printing shops that use digital size sheets and presses. Another way in which the 4200 favorably compares to the Martin Yale 400 is that the 4200's jogging tray is much larger, and has a bigger capacity. The reason this is such a great feature is that now we have the ability to increase speed on larger sheets and reduce it for smaller pages and some heavier stocks. That's just how they do what they do. The 4200 does have a small metal stop in place, but if you aren't careful, larger sheets may fall forward into the jogger, and cause you some problems. Martin Yale used to build the jogging tray for this model out of wood, but it is now metal. One feature we really loved, and one that puts the 4200 a clear step ahead of Martin Yale's 400 series is the adjustable speed option that lets the user adjust the vibration at which the machine operates to suit the material you are seeking to jog. 3.. Strengths: 1. It is clear to us that this is a machine capable of handling the biggest professional printing or mail room jobs out there with no problem. A heavy duty paper jogger, the Martin Yale 4200 is a specialized machine that can jog envelopes, tab cards, collated sets, checks, and just about any document that you need to bind, cut or fold. The nature of paper joggers is that they vibrate a lot. 2. With its all-metal construction, it is obvious to us that the 4200 is a heavy-duty machine built for high volume use. Most of the time you will just want to place it in the standard upright position. You may also want to keep other equipment off the table that the 4200 is sitting on, for the same reason. However, if you are working with collated sets, you can use this machine to do crisscross jogging if you have that need. 3. When you are using the 4200, the goal is to adjust the vibrating speed so the each page is getting individually vibrated. You may also want to put an extra piece of carpet underneath to reduce vibrations and noise. With the 4200, you can jog sheets as large as twelve by eighteen. Another great feature of the 4200 is that you can adjust the angle of the jogging bin. We found that by tilting the jogging bin back just a little Tiancheng Grain Drying Machine Suppliers bit, and keeping an eye on the process, we could correct this problem. Weaknesses: 4. Over time, though, these vibrations can cause some problems that you will want to watch out for. One way in which the 400 has an advantage over the 4200 is that the 400 has plates placed on either side of the sheets that are being jogged, which prevents them from vibrating right out of the jogging bin. This is when you achieve the best results. You will definitely want to check the nuts and bolts of the jogger and the table that it sits on periodically to make sure they are still tight.
