Question about Brother SX-4000 Typewriter

Print head and ribbon do not in sync

When I type, the typewirter hammer hit the daisy wheel head correctly but it did not hit the ink ribbon for print (so the output is all blank). The typewriter had been dropped to the carpet once (from a 2 feet high table). What might be the problem to cause that? Is this something can be fixed easily?

Re: Print head and ribbon do not in sync

Sounds like the ribbon carriage is out of position, try holding the shift, and code keys, then power up, if thats no help the hold frame might have to be resitted.

How do I insert the daisy wheel on my Swintec 2416 DM typewriter?

Remove the ribbon, then remove the daisywheel, reinsert daisywheel, replace ribbon and it should work.

  1. Is the daisy wheel locked in the forward position?
    1. Pull the black lever back, away from the platen.
    2. Lift out the daisy wheel and inspect it for damage; replace the daisy wheel if it is damaged.
    3. Re-insert the daisy wheel and push the black lever towards the platen until it locks in place.
  2. Is the ribbon moving?
    1. Lift the ribbon cartridge out of the typewriter
    2. Inspect the ribbon for damage
    3. If the ribbon is silver, it is exhausted and must be replaced
    4. If the hammer has been striking in one place, there will be a clear area near the center of the ribbon.
    5. Turn the colored knob on the left side of the ribbon cartridge counter-clockwise to advance the ribbon a small amount. Replace the ribbon if it will not advance.
    6. Re-insert the ribbon
  3. Turn on the typewriter, insert a piece of paper into the typewriter and type a few letters
    1. Did the hammer move forward?
    2. If the hammer moved, did the ribbon advance with each keystroke?
If the hammer did not move or the ribbon did not advance, the typewriter will require service. If the typewriter still does not make an impression on the paper, your typewriter will require service.

My typewriter doesn't type..won't display letters, but keys work.

alot of the brother t/w's have 2 cam assemblies under ribbon holder. 1 operates the print hammer and 1 operates the correction ribbon lift. sometimes these will hang or lockup. sometimes turning on and off a few times will take care of it, but sometimes it needs to be worked on by a t/w tech. if you look when you type a character, most likely the print hammer is not firing or it is striking the correction ribbon instead of the black ribbon.

No Characters Typing

could be the ribbon is not lifting, do you see an image on the ribbon, also may be twisted inside the cartridge the shiny side has to be facing the keyboard.

Typewriter suddenly will not print!

It's been awhile since I've worked on these.

What is the typing mechanism in here? I believe Brother was using a wheel.

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.

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...

Ok,there could be two possibilities ,1, The daisy wheel may not be seated in properly. Of course I assume that the print side of the daisy wheel is facing the platen and that when the typewriter is switched on the print unit makes its customary re-setting motion and that the daisy wheel spins around at the same time. if this does not happen make sure that the lock-in lever for the daisy wheel is pushed home.. I am sure that you do all these elementary things so the only other possibility is the the hammer seleniod is not fully functioning and would have to be re-placed....Good luck!
