Brother PC-420 Questions & Answers
What does error F2 indicate?
An error message from F1-F9, means the machine is malfunctioning, so it's best to see a technician who can fix it. You can't fix it yourself. Sorry.
How can I reset the stitch length?
Try resetting it according to the manual on page 56. First turn the machine off, unplug it and wait 2 - 3 minutes and re-plug it and turn it back on and reset the stitch length - the screen for the stitch setting will appear, the down arrow makes the stitch shorter, and up arrow makes the stitch longer. If that don't work you might have to contact sewing machine serviceman, or you might can call Brothers and they can help troubleshoot the problem.
How do I get the stitch length to be consistent? It changes with speed
consistent stitch length depends primarily on tension settings. there are 2 different tension settings on all machines. 1. upper thread tension. 2. bobbin thread tension. since these work together to create the correct stitch length+width, having either of these adjusted inappropriately can significantly impair stitch quality. "knowing' your machine has a lot to do with knowing how tight or loose the tension should be for BOTH settings. the settings will be different for each type of stitch, for each type of needle used, and for each type of thread used, meaning tensions will need to be re-adjusted after each change. in other words, the setting for a medium-width zig-zag with a size 10 needle using mercerized cotton thread to sew light-weight canvas will be completely different than the settings for a regular straight stitch using a size 8 ball tip needle using polyester thread to sew silky lingerie material.
Bobbin won't move

Can you turn the hand wheel at all ? If not, something is jammed tight somewhere.
Have you removed the bobbin from the bobbin case and cleaned thoroughly around it, removing all lint, dust, loose thread bits ?
If that does not help, can you try taking apart the shuttle assembly, which the bobbin fits into ?
Sometimes you may get thread wound around in these parts and it causes a jam. Please, observe how the parts of the shuttle assembly fit together so you know how to put it back together. There may be a small lever or pair of levers that must be moved to allow the parts to be pulled out. There aren't many, usually two or three pieces.
It's very useful to snap pics.. of it the way it looks before you touch it, and then each step as you take it apart, so you have a guide to putting it back.
It's also possible a gear is jammed. Most machines allow you to remove the upper casing and bottom casing. You'd have to take out some screws to do this. If anything is jammed between gears that you can see, remove it carefully. If you have to use a tool to pull out something jammed, take care not to damage the gear teeth, as that's a big repair job and often not worth the expense compared to buying another machine, sadly.
I dropped the feed dogs and they won't come back up.
Ignore all the other comments, they are wrong. The feed dogs are driven by the feed driver mechanism, turn the hand-wheel forward and the feed dogs will come up. (Providing you have the feed dog switch to the up position).
