    My Brother typewriter will now print letters but the letters are not syncronized with the keys, so if I hit K it prints "," etc.

    How do I fix this. 
    Also I am unable to easily install the new ribbon cartridge. How do I uninstall the correction ribbon cartridge to be sure that the two cartridges are properly seated.

What can be the solution's, I am typing the letters on the keyboard and it is printing all different characters on the paper -- is there a command set that should be cleared?

First pull out printwheel and see if the "spokes" are even and straight, Second try a new wheel, and third, on this Brothers, when you turn it on the carrier has to go to the left and you will hear the wheel turn and cycle to the correct home spot. Some times there is a arm that comes out of the left side frame that loosens up and throws the time off, check for loose bracket on left side. But a new wheel may solve the problem Good Luck.

The characters printed do no match the ones typed. I have taken the print wheel out and put it back several times.

Check the pitch slide switch on the L. of the keyboard, it should be in 10 or 12. If it is push down and slide it up and down a few times they do get dirty.

Hi, I have a 1967 Smith Corona Corsair portable typewriter with case. All works fine except that the ribbon does not lift when keys hit the paper. So the keys end up hitting the paper directly (not through...

Is the ribbon selector lever located on the right side of the keyboard switched to either red or black? If it's on white, the ribbon doesn't come up.

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.
