The machine features 50 embroidery designs and 10 fonts with 2 & 3 letter monogramming option. To top off the built-in collection, you may import up to 1,500,000 stitches or 100 designs to the internal 3 MB storage to expand your old techniques or keep to your own style preferences.

The 5.7-inch Remote Computer Screen, or RCS, provides remote access to all stored designs and fonts, displaying them in 65,536 available colors in order to make preview more realistic.

You can edit any selected style with the computer’s built-in editor to suit the aesthetic of each project. Once the design is selected, you can enlarge, reduce, rotate, drag and drop, re-edit, zoom, or arc it as well as combine several styles.

In addition to the RCS, the onboard sub-control panel with backlit LCD screen lets you customize all settings directly from the machine. Janome Artistic Digitizer Software ensures the correct operation of all digital features, adding a comprehensive feature package for improved accessibility.

Supplied along with a set of Janome branded accessories, the four main embroidery hoops are manufactured specifically for the use with the MB-4S machine, while the work field itself is compatible with six industry-standard Tajima hoops, making it suitable for different types of craft projects.

One of the standout components is the machine’s new bobbin design that measures 1.4 times larger than standard bobbins. Moreover, the upgraded bobbin winding motor—which you won’t normally see on professional embroidery appliances—is able to quickly wind a bobbin without interrupting the machine’s sewing process.

The work field and needle area are clearly lit by 4 white LED lights, giving you clear visibility of action at all times of day. As for embroidery sizes, the maximum hoop size of this model measures at the impressive 9.4” x 7.9”.

Built-in automatic thread cutter works for both needle and bobbin threads, while the automatic cutting of jump threads can be engaged even between letters. In addition, the machine offers programmable thread trimming for faster operation.

The positioning of all hoops can be adjusted depending on the project, and the thread sensors inform you if a thread breaks while the machine is sewing. Supported thread brands are Janome, Robison-Anton, Madeira, and Mettler.

The exclusive bonus package supplied with this machine includes additional hoops, namely Janome MB-4S Hat Hoop, Janome Lettering Hoop Holder Unit, Janome No.7 Lettering Hoop J8, and Janome No. 9 Lettering Hoop J6. These are best applied for accessory decoration, such as hat and shirt processing, as well as detailed lettering and monogramming.
