"World's First" Home-Use Four-Needle Embroidery Machine
Refurbished Janome MB-4S Four Needle Embroidery Machine
We've taken everything you love about Janome embroidery and quadrupled the capacity! With our four needle machine, you can set up your embroidery and move on to other projects while the MB-4S gets it done.
The MB-4S is built to work with most embroidery formats, including those used by industry professionals. It is compatible with six industry-standard Tajima hoops, as well as the four available Janome hoops to further expand your creative opportunities.
Key Features
NEW! Extra large bobbin
Extra large bobbin is 1.4 times larger than a regular bobbin.
Remote Computer Screen (RCS)
The Remote Computer Screen (RCS) gives you total set-up and editing control with up to 65,536 colors. One RCS can power many machines, saving the cost of additional controllers.
LED Light
The LED Light offers precise lighting for outstanding results.
Automatic Thread Cutter
The MB-4S automatically cuts jump threads - even between letters - saving you time and hassle.
Dedicated Bobbin Winding Motor
This feature - not found on professional machines - winds new bobbins even while the machine is stitching a design.
On Board Control
The MB-4S includes an on-board sub-control device. You can use it without the controller! The MB-4S also includes 3 MB of memory which can store up to 1,500,000 stitches or up to 100 designs.
Link Directly to PC
The on-board USB slave port connects directly to your PC with Digitizer MB software, sold separately.
