At some point, the machine has probably been over-oiled--perhaps not by you. If the oil is coming from the needle bar or presser foot bar, you can try cleaning those bars with a clean cloth to remove any excess oil. (Drop the presser foot and the needle so you can wipe as high as possible.)

If it continues to be an issue, you may need to have your machine cleaned.

Have you tried oiling all moving parts. Go under presser foot under bobbin and remove all lint. Try to change the needle.

look in the operation manual to see if it's self oiling or if you have to oil the machine, if you have to oil it, only oil the places it says In the manual..
clean under the needle plate and in the bobbin area for lint
when the machine is not in use, keep it covered with a cloth cover
also remember to use the right needle for the fabric being sewed

Oil? Maybe needs oil on that part of the machine.

contact brother customer service about the oiling.

No oiling a computorized sewing machine. These areas are factory sealed and only serviced by a Brother tech.

Refer to the care and maintenance section of the manual for cleaning as this needs to be done more often with sewing/embroidery machines that have the drop-in bobbin.

Look for thread snips and lint.

Raise the needle to it's highest position before removing and replacing the bobbin case.

You can get a manual, if needed at the Brother website to view or download at no cost.

Eventually you will have to take the machine in for service. The site has a dealer locator, if needed.

A lot of the newer computer models don't seem to recommend oiling. I went to the manufacters website for my machine- brother pc-420- to find out, because like you, there were no indications in my manual. Brother website informed machine was oiled plenty already and advised oiling could cause damage. Seems like a way to put services centers back in business if you ask me! My advice would be to call Simplicity and see what they have to say about maintenance. In the meantime I will be making the same call to Brother. Hope we both stay out of repairs. Good luck! =)

oil all moving parts and try turning handwheel by hand to work oil in. it really needs a service by a technician

More than likely the machine is okay but when you do the embroidery the presser foot is not all the way down and it has no tension. The other possibility is that the thread is not in the take up lever all the way or is slipping out.
