Question about Brother SX-4000 Typewriter

Hammer doesn't strike

I was typing along one day when the machine just stopped printing anything on the paper. the print head moved normally, and I could hear the wheel clicking as it moved, but nothing was on the paper. I assumed at first that I had simply come to the end of the ribbon, so I replaced it. Of course that didn't work or I wouldn't be posting this. I realized then that the hammer isn't moving at all. I tried every mode. I tried resetting the machine. I tried turning it off. I even tried unplugging the machine. Nothing helps.

Try taking the wheel out and aliging it with the piece in the middle with a hole in it so that the pin and the wheel connect when you push the lever forward to connect the wheel to the disk.

Is the hammer moving at all? There is a rubber part on the I think left side of the ribbon hammer, down on the side of the printer. This will adjust the amount of impact. I really doubt if
this is the problem, but worth a try to look at. This part and I think it is a blue slide will move up and down to adjust the impact. Possible lubrication and there is a large spring that actually pulls that hammer forward, check to see if this spring is OK. Other than that electronic problems such as main board, printer motors, etc. Does hammer move freely by hand? Also mechanical binding in the printer... GOOD LUCK.

Bought new Brother ML300 will not type anything on the paper, please help!


I would check all the basic stuff first. Is the print wheel locked into position? Is the platen all the way forward? (lever right side) Is the ribbon installed correctly and not cocked up on one side? Do you hear the hammer striking the paper? If you hear the hammer striking the paper, it is a ribbon problem. If you don't hear it, it is a hammer / print wheel problem.

Horizontal print gaps on ml184+


Hello,

The most common cause of missing sections in the letters is a bad print head. These types of printers (Dot Matrix) create the print with the print head which has a line of small pins called hammers that are activated by an electromagnet. Each pin has its own hammer. If the electromagnet fails or you have something jamming the hammer then it will not move to strike the ribbon and make the image or letter. You can get a replacement print head online for about $15.00, the part number is 50063802. Here is a picture of what the print head looks like. :

You need to adjust the print head spacing. This is a lever along the side inside the printer by the print head. It just move the head closer or further away from the paper. The closer it is the harder it strikes the bottom pages and it should print darker on them. If you get it too close it can catch the paper and cause a jam so you have to give it a bit more space. You may end up redoing this if you use a different brand or type of nc form paper. Just open the cover look for a lever on the side and lick it a notch (should show circles so go to the smaller one) and try printing. You might have to waster a few pages before it behaves but this is all you need to do.

Brother GX 36750 - I replaced the ribbon, re-installed the daisy wheel, reset the pitch, pushed CODE RESET, but the letters I type are not matching what is printed on the paper. I press 't' and it types...


When you turn on the machine (or press [Code]+[Reset}) the print head moves to the right side, the print wheel spins, and the ribbon jumps up and down, that is the machine resetting its self.

If a reset does not work the reset tab may be out of alignment. I would

  1. Power it off and then turn it back on and test to again.
  2. If it's still typing the wrong or unreadable letters then turn off the power, open the lid. On the bottom of the case there is a metal frame on the right side of the frame you will see a small metal tab pointing towards the middle of the machine. When the machine resets its self, it uses that tab as a reference.
  3. That tab is easily bent which causes the reset to be wrong. Most people can bend it by hand, DON'T use a pliers! The tab can break off completely. It does not take much pressure and it does not need to be moved very far at all. Just nudge it towards the back (or the front) power up and test it. It might take a couple of tries to either direction to get it right. Be ready to turn off the power if when the print head resets. If you bent the tab too far the tab will not enter the print head correctly.

This reset tab most often gets out of alignment by a child playing with the machine, but if a foreign object is in the machine when the print head is moving.
