Janome: The Company

Janome was founded in 1921 by Yosaku Osem. First named the Pine Sewing Machine Factory, it later became the Janome Sewing Co. in 1954. Now, Janome has divisions in the U.S., Canada, Mexico, Europe, and Australia, as well as many more countries.

Their stated mission is to provide sewing machines and sergers that are easy to use, reliable, and made of quality materials. They want to help users “make the most of their creativity.”

The Warranty

The Janome 4120QDC Sewing Machine comes with a 25-year limited warranty.

This protects any issues with the “materials or workmanship with the exception of electrical/electronic equipment, which is warranted for a period of two years from the date of original purchase.”

During the first year of ownership, you can receive replacements for any parts that are defective, as well as any labor free of charge. After the first year, defective parts can be replaced for free, but you must pay for labor.

The warranty does not cover anything caused by poor maintenance or repairs, nor does it cover any damage caused by “normal wear and tear.” The warranty only applies to machines that are bought through an Authorized Janome Retailer.


120 Stitches

This Janome sewing machine includes 120 different stitches and a built-in alphabet with three different fonts for monogramming.

The stitches range from basic to decorative to zigzag and fashion stitches. With this variety, you’ll never need a stitch and find this machine lacking.

Top-Loading Bobbin

This sewing machine has a top-loading bobbin, located near the needle plate for easy access.

This makes it simple to examine and address any issues, should the thread jam or the bobbin need rethreading.

Automatic Needle Threader

The machine also includes an automatic needle threader, so you’ll never strain your eyes (or patience).

To use the threader, lower the presser foot and raise the needle to its highest position. Pull the needle threader knob down. A hook will emerge from the needle’s eye.

Draw the thread through the guides and then slip it between the thread guide and the holder plate. Raise the threader knob up, pushing the thread through the needle. Pull it through, and you’re all set!

LCD Screen

Since this is a computerized sewing machine, it has a user-friendly LCD screen and control panel. This allows you to easily select the stitch type, length, and width.

You can also choose a pre-installed design or letter font, which the machine will create on your fabric effortlessly. For more customization, just visit the display screen and adjust the settings directly.

The Positives

Super Easy to Set Up

While this Janome sewing machine may look complicated, it’s anything but. By combining the automatic needle threader with the top-loading bobbin, you can have this machine fully operational in less than a minute.

Janome machines are usually intuitive and easy to set-up with simple guides to help you through. The 4120QDC is no different, leaving you with less to fumble with out of the box.

You’ll also have an instructional DVD guide at your disposal should you need some audio-visual cues! You won’t have to worry about being frustrated with this machine before you even begin!

While some sewing brands can be complicated to adjust to, Janome allows you to focus on other things, like actual sewing.

Very Easy to Use

We’re happy to report that using this machine is just as easy as setting it up.

Once the machine is threaded, you need only visit the control panel and the LCD display to choose your stitch type, length, and width, as well as your alphabet font or other options.

After that, just locate your fabric beneath the presser foot and use the lever to lower it down. Then, just press the foot pedal and get to sewing!

The learning curve on this sewing machine isn’t a big one – if you’re switching machines, you won’t be daunted when getting accustomed to this one.  A machine that’s easy to use makes it all the easier to tackle a variety of projects and grow with your machine.

The Negatives

Sews Up Some Noise

If you’re sensitive to noise or prefer to work in a quiet environment, this Janome may be a cause for some concern. Some users might find this sewing machine to be too loud.

The motor and gears inside generate more noise than expected. While this won’t be a problem for the majority of users, it’s worth noting for those of us who prefer a quiet machine.

If you’re particularly sensitive to loud sounds, this machine might get annoying. Or, if you live with housemates, you may not want to use this machine in the early morning or late at night, as it could wake someone up.

Not for Beginners

Due to the number of different options and features on this Janome sewing machine, it’s wise for beginners to try a less advanced model.

There’s a chance that it may be overwhelming, depending on how accustomed you are to sewing and sewing machines.

If you’re an intermediate or expert sewer, you should have no problem, but if you’re just starting out, you may want to wait before working your way up to this sewing machine.

On the Pricey Side

If you’re newer to sewing, this machine may also be out of your comfort zone due to the price and functions. That said, with all the features and craftsmanship involved, the price for this machine is understandable.

It will be up to you to decide if it’s worth it for your endeavours.
