On the lhs of the keyboard check the Pitch Sel slide switch position;...it may be in the PS position...change it to 10,12 etc, to match your print wheel.

change Cassette daisy wheel. with the letter

MAKE 7 model/ dICKYo

there is a slide switch on the L.H. side of the key board that reads 10,12,15, PS
the switch needs to match the print wheel stile you have in your typewriter. most typ's have 10 or 12.
PS stands for proportional spacing a takes a spicule print wheel

Check the print wheel to see if any spokes are bent or missing, be sure that you have the proper correction tape (tack free) and that you are not in proportional space or have an international print wheel.

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.

The printwheel has lost it's home position. Release the lever holding the printwheel, remove it and re-install it. Push the lever toward the platen to lock it in. Turn the typewriter on. The printwheel should spin, the carriage should move to the left and the come back to the left margin. You should be OK after that. Let me know if it helps or not Ed
