upper case number 2

very hard to do without breaking something. take to repair shop

it could be a broken wire in the harness from the control board to the hammer

Sounds like the drive clutches are out of sync or a spring has come off the hammer. You will need a trained tech to repair unit. I would go to brother-usa.com to find the nearest service center. Please do not try to take unit apart yourself, too easy to break plastic latches.

check to see that when yu replace the ribbon it has not slipped in front of the print ribbon and that you have not got the button for corection pressed by mistake it is using this to print you letters not the ink ribbon

it may have come loose from its post or something in the ribbon drive broke

press the cap lock key

You can only print the symbols that are on the keyboard.

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.

Go to brother.com you can download a manial there. DickyO

why not put some singer oil. maybe it is all dusted and dirty.. try to clean it once in awhile

Sounds like you have diagnosed the problem. Remove the correct tape and make sure that it's not the "sticky" type. (it will be hard to unwind if it is). Next try to manually lift the part that's supposed to move to see if it does. If it's sluggish (hard to move) put rags around it to prevent over spray and carefully clean all the moving parts with WD40. Make very sure that the WD40 does not get on any electronic parts! It will also mess up the platen. So, the more rags around the moving parts, the better. I used to work on IBM typewriters, and WD40 sometimes works wonders.
