The AMAYA thread feed rollers are consumable parts (need to be replaced periodically) because they wear out. Wear of the rubber on the thread feeder roller can occur because of the following reasons:
The rubber on the thread feeder roller is damaged quickly if the thread is pulled through by hand without lifting up the lever (pinch roller) before pulling the thread through. This leads to rough spots and nicks on the rubber belt, which will catch thread and pull it inside through the cover, causing birdnesting inside the thread feeder. For these reasons, it is important to pay careful attention to the thread and material feed settings.
Metallic and cotton blend threads can cause thread feeder rollers to wear out more quickly than Rayon or Polyester threads.
Thread feeder rollers of needles that are used the most frequently will wear our more quickly than others.
Tighter tension can cause thread feeder rollers to wear out more quickly.
If you are experiencing any of the following problems, it is recommended that you check the thread feeder rollers. It is possible that worn out rollers could be the source of the problem.
Birdnesting inside the thread feeder
Thread breaks
Inconsistent looking bobbin on the back of embroidery
Looping stitches
Skipped stitches
If you can easily pull thread without lifting the pinch roller, you need to inspect the thread feeder roller for wear/damage. Click here for instructions on removing the roller.
After the roller is removed, inspect it for nicks or a groove in the rubber (the following image displays a roller with a groove in the rubber). If the roller is damaged or worn, it needs to be replaced. Click here for instructions on installing the new thread feeder roller.
It is possible for rollers to become coated with silicone (from certain threads, such as rayon thread). This silicone makes the surface of the roller very slick. If needed, use a clean cloth to remove the silicone coating from the surface of the roller.
Follow the guidelines in the table below to troubleshoot thread feeder roller, pinch rollers, and other thread feeder issues.

|
Thread wrapping around thread feeder roller Clear the resulting "birdnesting" in the thread feeder following the procedures shown in "Clearing Thread from Thread Feeder Roller" |
Thread feed setting to high |
Decrease the thread feed. Refer to "Thread Feed Tab" in the AMAYA Operator Manual. |
|
Material feed too high |
Decrease the material feed. Refer to "Thread Feed Tab" in the AMAYA Operator Manual. |

|
Damaged rubber pad on roller |
Pulling thread through without lifting up the roller. (This creates a groove in the rubber pad or cuts it). |
Replace the roller |
|
Broken thread feeder arm |
Lifting or forcing thread feeder arm up |
|
|
Jumpy or uneven thread feed |
Broken teeth on drive gears. |
If the thread feeder gear on the thread feeder stepper motor is damaged, replace it. If the gears in the thread feeder assembly are damaged, replace the thread feeder assembly. |
