Re: Brother ML300 Typewriter

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

I should snap in try spreading the part it goes into, EAZY DOES IT

1 Answer

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.

Daisy wheel will go to the letter pressed, but the hammer will not strike. It moves along like it's typing, but the daisy wheel is the only thing responding.

The keys typed are not the letters coming up

The SX 4000 is a "Daisy Wheel" printer. A plastic Wheel with the letters embossed on them spin via the input of the keyboard. I would suggest that your Daisy Wheel mhas slipped its index, presenting a offset letter., or the wheel is on inproper, but I do not see how it could happen, short of forcing it on. You may have to buy another Daisy Wheel, if that one is broken at the hub. See:

My ML300 types wrong letters and I have done everything that the manual says to do. Where can I buy a new daisy wheel? I think mine has one tine overlapping another.

We have wheels in stock they are 39.95 including shipping, however the problem may be a broken printwheel homing pawl and you will need a tech.

Change font size on my bother ML 100

A typewritter is not like a computer. It is a mechanical device, that works by pressing an embossed letter in the daisy wheel through a inked tape into the paper.
The only way you can change either the font type or the font size is by buying and replacing the daisy wheel by another one with different font type/size letters.
To get to know more about your typewritter and accessories that might still be available to it, download Brother ML-100 Typewriter User's Manual
Click on "Go to View/Download Page" and in the new page click the "View/Download" button.
Look for page 16 (last page) of the manual for a list of cassette daisy wheels.

Cannot get daisy wheel to type correct letters

Turn oFF the typewriter, take the ribbon out.....use the lever on top to release and remove the print wheel cartridge. Lightly rotate it to see if it will move and reinsert the cartridge. snap it back into place.
Turn on the machine, the typewriter should move the carrier to the left and reset the printwheel....if it is snapped back properly.

Not typing the correct letters

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.
