Brother M-100 Won't Grip Paper

Best way is to remove the top cover, with out taking the Platen(large rubber roller) that the paper goes around out look to the rear there is a spring that breaks that puts pressure on a pan with feed rollers in it , replace spring or at least put a new hook in it or if you are lucky and it is not broke I could just be unhooked. Also clean all those rollers that are rubber with something nail polish remover. Do not touch plastic with this cleaner, it may melt plastic.

If nothing happens no carrier movementor paper feed you probably have a bad keyboard.
If the carrier moves but no feed the index motot may need to be lubed.
If the roll moves but the paper dosen't you may have debris on the paper tray or bad lower fed rolls.

The key I push is not the letter that prints

Many factors affect correct character selection. To isolate the problem, follow the directions below:

  1. Is the daisy wheel locked into the carriage correctly?
    1. Open the top, locate the black lever near the hammer and move it away from the platen.
  1. Lift out the daisy wheel. Inspect the petals to see if they may be damaged.

  1. Locate the small spring loaded pin near the center of the daisy wheel hub. If the pin is missing or sticking, or the daisy wheel has damaged petals, replace the daisy wheel.

    1. Look into the opening from where you removed the daisy wheel. Ensure that there is no debris in the area; use canned air to blow out the area.
  1. Reinstall the daisy wheel or install a new one if the old one is damaged.

  1. Remember to push the black lever towards the platen until it snaps into place.

  1. Close the top cover and turn on the typewriter.
    1. After the carriage moves to the left margin, insert paper, and open the top cover.
    2. Push the hammer forward until it presses the daisy wheel petal onto the paper.
    3. It will leave an impression on the paper; it should be a lower case "h".
    4. If the impression is any other letter than those above, the typewriter may require service.
  2. Examine the keyboard area. If there is any contamination, i.e. spills, pet hair, etc, the keyboard may need to be cleaned by a trained technician.
  3. If the problem is not resolved after these actions, the typewriter may require service.

While typing there was a metalic "clunk. The paper would no longer remain around the bar.

There is a strong spring tha holds the lower rolls on the paper it may have broken but more likely the plastic point where it hooks broke off.

Letters don't show on paper no imprint on ribbon. keys sound like they are typing but nothing shows on paper

Chances are that the print head is not locked forward. This happens when the daisy wheel or either of the ribbons are replaced. Just push it forward until it clicks

I need the letter key M/m for the Swintec 1146 CM model can you help me replace it?

If you are saying that the "M" key dosen't enter you can try this. Gently Pry the keytop off, Make a small paper spit ball, push it down the hole below the keytop, reinsert the keytop.
If one dosen't do it try two. If this doden't work you will have to replace the contact pad inside the keyboard.

You probably have a keyboard problem. With the T/W turned on tap the space up key and the micro up & down keys if they space without pressing them you may need a keyboard. If you find the offending key try popping off the key top this may get you by for a while.

First things first:
1) See if something is missing /part or something is broke on your unit.
2) See if some part when you put the paper is forcing in the wheels or a wheel is broke. to take out the paper.
3) replace if you can the system.
