If it is 2 vertical lines the printwheel has a bent or broken spoke.

Try this. Touch Keypad simulates a wireless phone keypad on the touch screen to allow you to enter text, numbers, and symbols just as if you were using a wireless phone keypad. Touch Keyboard simulates a 20-key QWERTY (typewriter) keyboard on the touch screen to allow you to enter text, numbers, and symbols similar to the way you would using a QWERTY keyboard. To use Touch Keypad or Touch Keyboard:  In a program, tap the Input Selector arrow, and then tap Touch Keypad or Touch Keyboard. To type lowercase letters, tap the keys on the dial pad or keyboard. To type a single uppercase letter, tap the Shift key and then tap the corresponding key. To type all uppercase letters, tap the Shift key twice. To change back to all lowercase letters, tap again. To enter a space after the word, tap the Space key. To start a new line, tap the Enter key. To backspace and delete a single character in any input mode, press the Back key. To open the Symbol pad, tap the Symbol key. To change the input mode:  Tap the Input mode key to switch to a different input mode: XT9 (predictive), Multitap (abc), or Numeric (123).

Hope this helps, let me know if this works or if I can help you with anything else.

With my IBM Thinkpad, I had to hold Shift+ScrLk to turn off Number Lock.

check to see if their is a keyboard selection switch on the keyboard.
It may have a setting that says international, symbol, standard, etc.

look for kb1 and kb 2 or your pitch is selected at ps instead of 10 or 12

Is the hammer striking the paper? What letters print when you press a key? Can you determine if the printwheel is turning?

Your are on the wrong keyboard setting. Look around the typewriter,usually on the left side of the keyboard, and you will see a setting 1,2 or 3. Keyboard one is the one you want.

The ML-300 needs to be reset each time the Daisy Wheel is removed or replaced or if the Keyboard Switch changes position. According to Brother, if this is not done the typewriter will print incorrect characters. Try these steps: 1) Open the Top Cover. There is a lever directly behind the Daisy Wheel. Pull the lever back towards you. Remove the Daisy Wheel by pulling it up and out. 2) Verify that it is the Standard Daisy Wheel that came with your machine and not a Symbol or International Daisey Wheel. Write down the Pitch (10, 12, or dual pitch 1012) printed on the wheel. 3) Reinstall the Daisy Wheel (the plastic top ear goes to your right.) Push the lever (step 1) forward. 4) Press the ALT key plus the PITCH key and the number 1 key simultaneously. Verify the Pitch setting is the same as is printed on the Daisy Wheel. 5) Press the CODE key plus the RESET key and the letter Q key simultaneously. This will reset the typewriter mechanism and align (or time, in technical terms) the carriage mechanism. Check if the typewriter prints correctly now. If still incorrect, perform these additional steps. 6) Verify the three position Keyboard Switch (inside the top cover, on the right side, at the bottom) is in the I=Standard position. The other positions are: II=International and III=Symbol. 7) If the Keyboard Switch is in the correct position, slide it to position III and then back to I. (This will clean the switch contacts in case they are dirty and not making good electrical contact. 8) Press the CODE key plus the RESET key and the letter Q key combination again to reset the typewriter mechanism. Check if the typewriter prints correctly now. If still incorrect, the only other things I can think of is that: 1) an incorrect Daisy Wheel is installed that does not work in the ML-300. Brother sell a "B type" Daisy Wheel with two plastic ridges/raised slots below the center of the Daisy Wheel (viewed with the raised top tab on your left.) The B type are incompatible with your machine. 2) the typewriter has failed and needs repair.

Your T/W neads a new keyboard membrane, you cannot clean this type membrane so you will have to replace it.
