Question about Brother ML-100 Typewriter

1 Answer

How does the print head on a Brother ML-100 sense when it has reached the left hand side after a carriage return?

I am working on a project that uses the print head from this ML-100 typewriter, and I would like to understand how the position sensing works. I have removed the print head and examined it closely, but without tearing it apart, I am having trouble understanding how the sensing works. I have tried finding a service manual online, but so far no luck. Thanks for reading this!

When the print head reaches the left side it touches a switch to cause it to inter the setup for the print wheel and ribbon mechanism

Testimonial: "Thanks for the quick reply. I see a small cone-like thing on the left side of the carriage area intrudes into the print mechanism as the print head moves to the left. This pushes a white lever of some sort, but it doesn't seem to do anything, and I don't see any microswitch (yet), nor do I see how it sends that position information back via the wiring to the control circuit board. Any additional clues? Thanks again :-)"

    Thanks for the reply, but this isn't anywhere near specific enough. There are three sets of wires in the harness in total, and none of these lead to any kind of sensor in the print mechanism. One set is used for the stepper motor that moves the print mechanism down the paper via a rack and pinion system. A second stepper motor is used to select the letter on the daisywheel, and a final pair of wires is used drive a DC motor that has multiple purposes.

I am working on a little project to use the print mechanism from a brother typewriter (ML-100). Unfortunately, I have been unable to find service manuals anywhere for this typewriter. My current q


I found a small piece of plastic caught under neath the carriage
of my Brother GX-6750 Electronic Typewriter. The piece looks as if it slipped onto some type of small end cylindrical peg one sixteenth long and one thirty-seconds in diameter. The piece has a lip where it latches on to something and the other end is flat with a tiny edged lip. The middle piece is where some peg goes into it and the piece is one piece. The carriage works improperly and fails to type. The hammer mechanism won't move forward on it's pivot to punch the daisy wheel. When the keys get punched, nothing happens. I just bought the GX-6750
through ebay and it arrived that way today. I'm looking for suggestions to get it fully operable.

Use your space bar to move carrier to desired location, hold down Alt key button on bottom left (next to space bar) and press the number 5 numeric key on top row. That should set your right margin.

How do i release the left and right margin


Move the carriage (print head) to the margin you would like to clear. When you hear the beep, hold down the [ALT] key and press [6]. Now use the backspace or the space bar to move the carriage to where you want the margin set. Now hold down [ALT] and press [7] to set the left or [8] to set the right margin.

Brother MFC 240c error 30 after printer jam.


Several conditions may cause the error message Machine Error 30, 33, 34 or 35 to be displayed on the LCD. This error may be the result of one of the following:
  • The print head carriage is failing to return to its home position to the far right of the unit.

  2. Using the dial pad, press 2 (Replace Ink). The display will prompt you PLS OPEN COVER.
  3. Pull the Scanner Cover release lever located under the Control Panel and lift the Scanner cover. The carriage should move to the left in order to replace the ink. If the carriage does not move to the left, your machine will require service.
    If your machine is still within warranty, click here to locate a Brother Authorized Service Center in your area or click here to obtain contact information for the appropriate Brother Customer Service Center.

  4. After the carriage moves to the left, press down each cartridge cover and remove all ink cartridges from the machine. There are 2 springs located on each side of the carriage that hold the print head against the carriage assembly. They are thin silver springs approximately 2 1/2 inches, set at an angle.
  5. If the spring is out of place, press the spring back into place. You can use the spring on the opposite side of the carriage as a guide as to the correct position.
  6. If the spring is not out of place, reinstall each ink cartridge.
  7. After installing the ink cartridges, close the covers and verify they are securely locked into place. Your machine then prepares for a head cleaning and goes online. The LCD screen prompts you to verify if a new ink cartridge was inserted for each color you removed. For example, DID YOU CHANGE BLCK 1. YES 2. NO.
