This is a replacement belt for the light scanner used on White, Superba and Singer knitting machines. This listing is for the belt only and does not include the copper clips.
The designer of this product makes no claims or warranties as to its quality, longevity or value. You are buying this product at your own risk and assume all responsibility for all damages incurred during installation and use.
The belt is manufactured from Shapeways' "Strong & Flexible Plastic". Per Shapeways, the material is heatproof to 80ºC / 176ºF degrees and higher temperatures may significantly change material properties. I have not monitored the light scanner to determine how hot it gets. That may or may not be sufficient. I’d strongly suggest you keep an eye on things during initial use. You may want to go as far as periodically removing the cover to check the surface of the belt for any warping, slippage, discoloration or other symptoms of heat stress.
I'll be posting photos, video and an installation guide as soon as I can get them done. In the meantime, here are a couple of tips to get you started:
- Detailed instructions for replacing the belt and sensors are in the vault (see section E around page 5).
- When you receive your belt, it may have a light coat of plastic dust produced during production. I'd recommend washing it in warm soapy water and allowing it to try completely before installing.
- IMPORTANT! If you're ordering one of these, chances are you're replacing a broken belt that can easily be removed from the scanner. The first bit of advice is to ignore the initial assumption that you should install the clips on the belt, then install the belt on the scanner. This is what I did and the result was a broken clip. The copper fingers on the clips are extremely fragile and there's a much easier way to install them on the belt.
- Use a #2 (or #1) phillips head screw driver to remove the clips from the old belt. Each clip consists of three pieces: the screw, the cap and the housing for the photosensor. On the bottom of the photosensor, you'll see a slit. With the front of the box facing you, that slit rides on the back rail of the design card guide assembly. If you look closely, the back rail is slightly bigger than the front rail.
- Mount the belt on both belt sprockets making sure the teeth on the belt are securely seated in the sprocket. The three pairs of extruded teeth should be facing the back of the light scanner. Note that while the belt will rotate cleanly, it will not stay centered on the sprocket until the clips are in place.
- With the front of the box facing you, slowly slide a photosensor (the bottom piece of the clip) onto the back rail from the left-hand side. As you do so, use a small flat-head screw driver to guide the first copper hand into the channel between the two rails. As you continue to slide the clip onto the rail, do the same for the other copper hand.
- Position the photosensor in the middle of the rail where it's stable and easily accessible. Rotate the belt to center one pair of extruded teeth on the photosensor. While holding the photosensor in place, gently life the belt up and drop the two extruded teeth into the two sockets on the photosensor.
- Center the top of the clip on the photosensor. You may need to fiddle with it a bit to lock it in place. If you're lucky, you'll hear a little click when it locks. I'd recommend practicing on a loose clip so you know what it's supposed to look like. Once you have the top mounted correctly, attach it with a screw.
- Continue rotating the clip towards the right side of the box. The clip should easily glide under the right bracket and around the socket. If it hangs up, chances are the top of the clip isn't mounted properly. Using your finger to keep the belt on the sprockets, make sure the clip rotates cleanly a full 360º in both directions before mounting the remaining clips.
IMPORTANT! As the clip moves around the sprocket, make sure the fingers on the copper hands are securely between the rails. The replacement belt is slightly thicker than the original due to the printing capabilities of the material. If the shortest forward-facing finger isn't securely behind the front rail, it will catch on the rail as it rounds the curve, the finger will bend and ultimately break. It is particularly noticeable when rotating the belt in a clockwise direction and the clip is moving around the sprocket towards the top of the scanner. If you hear a scratching noise, it means one of the fingers isn't where it should be.
- Repeat the process for the other two clips. After all three clips are mounted and secure, do another one or two rotations to make sure the belt is tracking properly, the clips are rotating cleanly and the copper hands are riding between the two channels.
