The E-B1 error on a Brother embroidery machine indicates a problem with the input/output controller. Here are some steps you can take to fix the issue:
- Turn off the machine and unplug it from the power source. Wait for a few minutes before plugging it back in and turning it on again. This can reset the machine and clear any temporary glitches.
- Check the embroidery hoop. Make sure it is properly attached to the machine and that there are no obstructions or interference.
- Check the embroidery design. If you are using a pre-loaded design, make sure it is compatible with your machine. If you have created your own design, check it for any errors or issues.
- Check the input/output controller. Make sure it is clean and free from any debris or dust. If it appears to be damaged, it may need to be replaced.
- Check the machine’s connections. Make sure all the cords and cables are connected securely and that there are no loose wires or connections.
If these steps do not solve the E-B1 error, it may indicate a more serious problem with the input/output controller or the machine’s internal components. In this case, it is best to contact a qualified technician or the manufacturer for assistance
