MB-4S
Step up to multi-needle production with the Janome MB-4S four-needle embroidery machine! Engineered to set up projects and execute stitching independently, the MB-4S accepts professional industry formats and multi-hooping setups across 6 standard Tajima hoops and Janome hoops. Featuring 50 built-in designs, 10 monogramming fonts, a 5.7" Remote Computer Screen (RCS), a Sub-Control Panel, 1.4x extra-large bobbins, high-speed 800 SPM performance, and direct PC link connectivity, the MB-4S delivers commercial-grade speed and reliability.
Dual Interface Control: RCS features start/stop, auto-cutter, trace, jog, carriage return, stitch travel, and movie help keys. The built-in sub-control panel handles stitch counts, color section settings, needle bar selection, and tracing without attaching the RCS.
Effortless Swaps & Extended Stitches: Front-loading vertical hook allows quick bobbin changes without removing the embroidery hoop. Uses extra-large M-style bobbins holding 1.4 times more thread than standard bobbins, paired with an independent auto-stop bobbin winder.
Professional Versatility: Compatible with 6 Tajima hoops and Janome hoops (includes M1, M2, and M3). 50 built-in designs and 10 monogramming fonts can be edited on-screen: enlarge/reduce, rotate, turnover, drag & drop, re-edit, zoom, arc, and combine.
Precision Optics & Color Management: Built-in thread brand selection matches Janome, Robison-Anton, Madeira, and Mettler colors accurately. Illuminated by 4 eco-friendly white LED lights across the work area for shadow-free visibility.
Four-Needle Setup
Four Colors, Zero Rethreading, With Colors That Match
Four dedicated needles let you set up four thread colors at once, so multi-colored logos and motifs run straight through without stopping to manually swap thread between colors — and built-in thread brand selection matches colors accurately across Janome, Robison-Anton, Madeira, and Mettler.
Remote Computer Screen (RCS)
A Remote Screen With Every Control You Need
The 5.7" Remote Computer Screen puts start/stop, auto-cutter, trace, jog, carriage return, and stitch travel controls in one place — plus a movie help menu when you need a visual walkthrough instead of a manual.
Sub-Control Panel
Run the Machine Without the Remote Screen Attached
The built-in Sub-Control Panel handles stitch counts, color section settings, needle bar selection, tracing, and LCD brightness on its own — no need to have the RCS attached for basic operation.
Front-Loading Vertical Rotary Hook
Swap Bobbins Without Removing the Hoop
The front-loading vertical rotary hook lets you change bobbins directly from the front of the machine — no need to unhoop your project just to check or replace the bobbin.
Extra-Large M-Style Bobbins
Bobbins That Last 40% Longer
Extra-large M-style bobbins hold 1.4 times more thread than standard L-style bobbins, meaning fewer bobbin changes across a long production run.
Independent Bobbin Winder & Spool Stand
Wind a Bobbin While the Machine Keeps Stitching
An independent bobbin winder with an auto-stop sensor lets you wind a new bobbin while the machine is actively embroidering — no pausing production to get the next one ready. A 4-spool front sewing stand keeps active colors ready, with a standby row and a dedicated rearmost pin just for bobbin winding.
On-Screen Design Editing
Edit Designs With a Full Toolkit
On-screen editing covers enlarge/reduce, rotate, turnover, drag & drop, re-edit, zoom, arc, and combine — enough control to adjust a design fully before a single stitch happens.
4 LED Lights
A Workspace Lit for Precision Work
4 eco-friendly white LED lights illuminate the work area from multiple angles, keeping close embroidery work — tight color changes, small text, fine detail — visible without shadows getting in the way.
