Janome 350e embroidery machine is saying "short of memory space the file cannot be saved".

Try reading the USB memory stick on a PC to verify it functions.

Try formatting a new or different known good memory stick using your sewing machine.

Update--as in software? Probably your Janome dealer...

Try unplugging it and plug back in might reset

Machine memory is FULL. delete a few designs from the machine, and then you should be able to load a new design from the USB Drive.

Your machine memory is full, delete a design or two from the machine's memory and you should be good to go with the new design.

High Shank Machines are all the Janome Embroidery models MC 8000, MC 9000, 10000, 10001, 11000, 200E, 300E, 350E....etc
If yours is not an embroidery machine, it has a LOW SHANK .....the higher shank allows for easier access for the embroidery hoop

Your space is not formatted correctly to the size of the hoop. For example if the hoop is 5x7 your design has to fit within that space, and the space cannot be bigger than 5x7. Strange but true and it will fix the reboot and shut down issue.

There are different programs for 350E. I think, you was buy program different.

Firstly, format your compact flash card on your embroidery machine. This is presuming you have embroidery files in your jef format your machine reads on your computer. Place your compact flash in the compact flash card reader writer connected to your computer, open the compact flash card in your computer, open the file emb5. Now you can simply copy and paste a design from your computer to your flash card. It works for me. Goodluck.
