I have a Sharp Elsi Mate EL-334A model caculator and my display is still not working right even after installing a new battery, is it toast? Or, is there something else wrong? This has been a really good calculator and I would hate to have to toss it out. Thanks for your help!

Easy. Press M- key [has RATE SET] above it. This will shown your current setting say 17.5. Amend to 20.0 and Press M- key again. Rate should now be set at 20%.
Test by entering:
100 and pressing +TAX key - Answer should be 20.
100 and pressing -TAX Key - Answer should be 83.33
Not knowing what to do, I tried anything that could possibly help: I installed fresh batteries and I pushed the reset button on the back of the calculator (Sharp EL-546L) and finally, it work all right after more than 5 years I own the calculator and where it did work correctly for 5 minutes. I tried the reset button in the past (long time ago) and it didn't work. This time it worked because, maybe, I've used fresh batteries. Marcello
If the model is EL-2125 , and not 2125C or 2125E the following will work
2)press CE and then CA (you should see 0. with small 00 in top left hand corner but nothing else)
3)press M- button (rate set button),current tax rate 17.50% will appear with tax at left hand side
4) type new rate eg 15.00 (making sure to hit the decimal and two zeros, tax at the left and % should still be on the screen)
5) press M- (rate set button) (small 00 will appear in top left hand corner)
6) press = ( new rate and G will appear small 02 in top left hand corner and = sign below it)
hope this works for you, please let me know either way
Sounds like the printwheels are out of time. Sorta of major repairs. gears on side of printer have to be lined up in proper areas. there are small black arrows on the gears. Best bet is look at a working machine and try to line up. Machine may not be worth the time unless you jsut want to try it. Sharp uses the same printers in many different models.
