I have checked the print wheel, and performed the [code]+[reset]. Most characters print correctly except for the following: f=@ j=[ v=# !=$ @=v #=& $=* (=% )=( -=/ _=? J=f. Any help would be greatly appreciated!!

First try opening and closing the top cover. If that does not reset the print wheel to the correct characters, check and make sure the correction tape is not interfering with the wheel as it spins. If that is not the case remove the print wheel and make sure non of the spokes are bent. If they are you can try bending them back to the right position or you may have to replace it.
REMOVE & RE-INSTALL THE DAISY WHEEL, MAKING SURE THE HOMING PIN IS IN THE HOLE NEAR THE HUB OF THE WHEEL. IF IT STILL DOESN'T PRINT THE RIGHT CHARACTERS, THE PRINTWHEEL MOTOR OR MAIN BOARD COULD BE BAD. TOSS IT AND BUY ANOTHER MACHINE
Geno111 doesn't know what he's talking about. Look closely at your correction tape once it has passed the daisy wheel. Does it looked roughed up a little? I just had this same error and discovered that my daisy wheel was hitting my tape when spinning and not allowing it to jump characters like it needed to. I simply put a little double sided tape on the daisy wheel cover between it and the metal tab that holds the ribbon at a certain distance, to increase the space the daisy wheel has to spin. It seems to have worked so far. If anyone has a permanent solution, or answer as to how it spins wobbly, I'd love to hear it.
I downloaded the manual from http://www.devicemanuals.com/downloadguide.php and then, following the instructions there, I removed then re-inserted the daisy wheel. This solved my problem. Perhaps it had somehow gotten out of adjustment. At least, it is something to try if you haven't tried it already.
Assuming that you have the correct print wheel fitted and that the typewriter is on standard key board setting then I would look at anything that might be interfering with the rotation of the print wheel. First, remove the print wheel and check that none of the character arms are distorted,then look at how the correction tape is fitted. If this tape is not fitted correctly it could be interfering with the rotation of the 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.
Normaly this would not be a user adjustment, possibly the grub screw hold the wheel hub to the motor has come loose, very small allen key needed, you make be able to shift it back to right place.
Usualy this is done with special alignment jig
Does it always type the same wrong letter ie
a always prints u or w ? if so the print wheel drive gear is out of position. if not and it get random letters some thing may be interfering with the wheel rotation.
