How can I fix my cash register,Tec Electronics,MA-1400A-100?

If you happen to own a TEC MA 1100 model cash register, the above answer from Jacob (Sept. 2008) will reset your register too. You also have to have the TEC "S" (service) key to do this ! My register had a problem for over two years and until I used instructions from Jacob as above. Thanks to Susan Albright for the question, Jacob for the answer and "How to mend.com" for giving us All the answers !

You will have to reset it.
Use the service key (the one with the "S") on it and move it one past the "Z" position.
Turn the register off.
Press and Hold the "0" button as you turn the register back on.
Release the "0" button and turn the key back to the "REG" position and then press the "No Sale" button.
This is a fix from the MA-1450 model but it does work with the MA-1400A-620 model and it might work with the MA-1400A-100 also.
Hope this helps.
(I know this, because it just happened to me and this is what the service guy told me to do)
