Brother ML100 Typewriter:All of the sudden, it just won't type. It seems the 'hammer' doesn't hit the daisywheel. We've replaced the daisywheel, corrective tape, ribbon and still it goes through the motions of typing but nothing actually types.

So many 'AX 100', but none have a daisywheel.

Looks like it might be an antique Brother typewriter? Try lubrication or the hammer unit with switch cleaner.

..

The ink ribbon cartridge is either used up or missing.

Check to see if you are in the display mode (it displays what you are typing, the carriage moves along, but only prints when you hit the return key)

Probably the print wheel homing pawl is broken you need atech.

Turn the machine off and allow it to rehome itself. If that doesn't help the printwheel homing pawl is probably broken. you will need a tech.

First, be sure you are using a Brother compatible daisywheel. Some other manufactures' daisywheels "look" the same but the charters are in different order, so they will not function properly.

If you have not changed the daisywheel, the next thing to check is that the wheel is correctly installed. The easiest way to check it is to remove and reinstall it. To do that;

1. Open the top cover.

2. On the right side of the hammer (the metal piece that strikes the daisywheel) there is a small lever (see attached figure). Pull that locking lever towards you to release it.

3. Remove the cassette that holds the daisywheel.

4. Reinstall it, making sure that you lock the lever towards the paper roller.

5. When you close the top cover the carriage (otherwise known as the print head) will move to one side and do a procedure known as "Homing."

6. Test the machine. If it is still mistyping, continue with the next part. Continued in part 2

The letters on the Daisywheel have slightly curved faces to match the curvature of the paper around the platen and the hammer will contact the letters and apply pressure to the top, bottom left and right depending on where it is adjusted. Test the machine by typing Capital MWMWMW and also /////// along with the rest of the alphabet including gggyyyqqqppp. The solution may be as simple as replacing the Daisywheel (may be worn from use). If all of the letters strike more heavily on the top than the bottom, the hammer may be adjusted closer to the paper which will apply more pressure to the bottoms of the letters. Also the face of the hammer could be worn and need replacement. If the Daisywheel is in good shape, you might try adjusteing the hammer position, but it can be tricky to get perfect.

The typewriter will print the incorrect letter, or the face of the hammer if it does not spin properly to the correct position. 1. Turn the machine offf for 15 seconds and turn ON, or Depress MODE RESET(the Q key). This will rehome the Daisywheel.I If it prints correctly for awhile then looses its' position, check for ribbon or correction tape interference with Daisywheel movement. If it does not print correctly as soon as you start typing, remove the Daisywheel and inspect the spokes to see if any are bent. Reinstall the Daisywheel and power ON. If the Daisywheel has a bent spoke or two, you can try to straighten them, howvever the cause of bent spokes is a concern. While typing, carefully watch the print hammer movement. It should always return to the same position and not move towards the paper until a letter is pressed. If it does not come to rest properly, the hammer is not in proper timing and may enter the Daisywheel while it is spinning to the character, thus causing damage to the Daisywheel or causing it to lose homing. .The hammer cams would require adjustment ore replacement. If bent spokes is a persistent problem, make sure to get the hammer problem repaired before buying a new daisywhel.

Removed and reinstall the Daisywheel. Inspect the ribbon and lift-off tape to eliminate interfering with Daisywheel spinning. Make certain the daisywheel has no bent spokes. Type slowly while carefully watching the hammer come to rest after printing. If you see the hammer moving towards the paper after a print cycle, the hammer is probably causing the Daisywheel to lose homing and will need to retimed or have the hammer cams assembly replaced.
