Candace, while not familiar with the 4.2, I've had thread jams on my trusty old Pfaff. I hope this helps!

If you are able to totally remove the bobbin cover/stitch plate, please do so. Ideally, there will be one or two screws holding it in place.

remove the bobbin

carefully inspect the bobbin housing; thread likes to hide behind the housing. If you find some thread, use a tweezers to remove it.

If no thread is found, see if there are one or two screws holding the bobbin holder/raceway in place, or just a lever. Try to remove the bobbin holder, carefully noting what the orientation is of all pieces is (using a cellphone to capture pictures of before and after is great!).

Clear any threads from the raceway, carefully re-assemble everything, test and good luck!!!

SOURCE: Threads knotted under the plate in the feed dogs.

Some sergers have a threading guide inside the door on the front of the machine.

If you need a manual, please provide the brand & model.

SOURCE: Pfaff quilt expressions 4.0 shows

A lot of these Ex 4.0 have defective cutter motors. The arm that the cutter is attached to passes by a sensor that tells the machine when the cutter is at the rest position. And what is happening is that the arm is no longer in place to tell the sensor where it is, and it stops short of the rest position. This part is covered by PFAFF for a 5 year period. You'll just have to have a PFAFF dealer install it and pay a labor charge.

Not sure what the problem is but you might try this:

Remove the top thread completely from the machine.
Make sure the machine is cleaned under the needle plate, the hook/bobbin area, the feed dogs, etc.
If your manual instructs oiling, do so as described.
Confirm that the feed dogs are in the raised position.
ALWAYS RAISE the presser foot then rethread the top thread from the beginning.
Verify the thread path is correct.
Confirm the needle is installed correctly (does the flat part face the right direction?). Is it the right needle for your machine.
Set the top tension to the midway point.
Check that the stitch length is set to at least #2.
Re-test your machine. Tweak the top tension until the top and bobbin threads meet in the middle of the fabric.

Some machines have a presser foot pressure adjustment that increases or decreases the amount of pressure the presser foot applies to the fabric and the feed dogs. You may need to increase this pressure.

Where can I locate the fuse<


Hello,

The Pfaff 7570 Creative Designer is a computerized sewingand embroidery machine that has the ability to connect to the computer, andhave embroidery designs sent to the embroidery machine. The sewing andembroidery machine has many features, including hundreds of general sewingfunctions, a separate embroidery module, and on-screen editing features. TheCreative Designer 7570, manufactured in the 1990s, was the first sewing andembroidery combination machine ever made by Pfaff.

1. Usingthe Sewing Machine
1 Turn on your sewing machine using the "On"button located just below the turn wheel on the right side of the machine.Thread your Pfaff 7570. Note that Pfaff sewing machines thread from left toright, not right to left like other sewing machines. The upper tension discsshould be raised at their highest position while threading, and the presserfoot should be raised up until you thread the needle. Drop the presser footright before you thread the needle. The prevents thread problems during use. 2 Insert a full bobbin and retrieve the bobbin threadthrough the thread plate. Raise your sewing foot and needle to its highestposition; hold the needle thread taught with your left hand, lower the needleinto the thread plate using your right hand, and then raise the needle. As youraise the needle, the needle thread will catch the bobbin thread, and pull itup. There should be a loop of thread intertwined with the needle thread. Usetweezers, your finger, or a straight pin to retrieve the bobbin thread that isvisible through the thread plate, and pull it through the plate. 3 Place the fabric under the presser foot, and drop thepresser foot. Choose the stitch you want to use from the top stitch display,right above the top thread feed. Press the '0-9" button located on thesewing machine's front panel, and a display screen will come up. Input thethread number, and press the 'OK' button located on the sewing machine's frontpanel. The stitch will display, and you are ready to sew. Repeat Step 3 foreach stitch you want to use.

2. SettingUp the Embroidery Unit
1 Turn the sewing machine off. Take out the embroiderymachine unit, locate the connection bushing on the back of your embroideryunit, and match it up with the connection bushing on your sewing machine. Theconnection bushing should be located next to a yellow sticker on yourembroidery unit, and somewhat resembles a serial port on a computer. Slide theembroidery unit onto the sewing machine with the sewing machine turned off. Connectto the bushing carefully as you slide the embroidery unit onto the sewingmachine. Use your embroidery unit manual if you need assistance. 2 Insert an embroidery card. Your embroidery unitshould contain an embroidery card labeled embroidery card 1. Use that or useanother Pfaff 7570 card that you own. Turn on the sewing machine. 3 Open the bobbin case area just below the threadplate, and lower the feed dogs by pushing the feed dog switch to the right.Press the card button located on the front face of your sewing machine. Adisplay with pop up; choose embroidery designs or monogram and a new screenwill pop up with your design choices. Choose the design you want, and press"OK." A checklist screen appears. Do everything on the checklist, andpress "OK." Use your embroidery unit manual if you need help. 4 Start embroidery by pressing the foot pedal. At thistime, your hoop should already be attached to the embroidery unit becauseyou've already gone through the checklist. Your embroidery manual displayscolored picture diagrams that are very helpful in understanding everything inyour checklist menu.

The first few stitches are just fine but then the machine seems to seize up and stops. When I try to remove the fabric I can barely lift it and then I must cut through a veritable bird's nest of threads on...


You may have a jam under the needle plate. Take it off and have a look.
It is often a simple case of one of the threads not passing through the tension discs correctly. Try re-threading upper and lower, making sure the presser foot is up at the time.

Are you sewing a fine material? Sometimes fine fabric gets pushed down through the universal needle plate hole which is slightly elongated. If this is the case you need a straight stitch needle plate. You cannot do zig zig or anything other than straight stitch with this plate.

If re-threading does not do it and you do have a soft fabric, try popping some freezer paper or similar under the first few centimeters of sewing before buying another needle plate, it might work.

Tension Problem on Pfaff 2034, bobbin loops


Rule of thumb.. Loops on the bottom, problem on the top. Loops on the top, problems on the bottom.

Set your upper tension at 4, and rethread the machine from the top. Just before you thread the needle, but the presser foot down. If the thread pulls right thru easily, then the thread is not thru the tension wheel right. Because, if you can't pull the thread thru with the presser foot down, you have it threaded right.
