Question: Your answer about the 550e is the best I’ve seen! I am having issues with my 350e. I’ve used it for years so I usually have no problem. Now it doesn’t read new USB sticks, but still reads older ones. I tried 2GB sticks and formatted them to FAT32, but designs don’t appear. Any advice?

What Usually Works with the Janome 350e

• USB size: 1GB–2GB only (larger drives often fail)
• Format: FAT16 (most reliable for older machines)
• File type: .JEF only
• File location: Use machine-created folder (EMB or My Designs)
• File name: Max 8 characters, no symbols (example: bear.jef)

Step-by-Step Fix

1. Format USB to FAT16

On Windows, open Command Prompt and run:

format X: /fs:fat

Replace X: with your USB drive letter.

Alternatively, use a formatting tool like HP USB Disk Storage Format Tool.

2. Let Machine Create Folder Structure

• Insert empty USB into Janome 350e
• Let machine create folders (EMB / My Designs)
• Remove USB and connect to computer

3. Copy Files Correctly

• Copy ONLY .JEF files
• Do not create subfolders
• Keep file names short and simple

4. Reinsert USB

• Insert USB back into machine
• Go to Open → USB
• Check if designs appear

Extra Tips

• Avoid Mac formats, exFAT, or NTFS
• Do not rename machine-created folders
• Use simple USB drives (no encryption or partitions)
• Recommended brands: SanDisk, Kingston, Verbatim

If It Still Doesn’t Work

Please provide:

• Your computer type (Windows or Mac)
• USB brand and model
• Whether the machine can save files to USB

We’ll help you troubleshoot further 😊

Conclusion

The Janome 350e is sensitive to USB format and file structure. Using FAT16, correct file naming, and proper folder placement solves most issues.
