Hi,
a 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of.(from cars to computers, handyman, and even drones)
Goodluck!

Press the CA button twice. Then push and hold down the %/set key until the 0 dissappearsd and reappears. Then type in your tax rate and the percent key (eg: 8.25%) and then press the TAX+ key. It should save the new tax rate.

SOURCE: Tring to subtract

With an adding machine, which is what this is, you enter the number followed by the + or -. If you wanted to add 10+20, you would enter 10 then + then 20 then +. This would show your answer. If you are using the printer and you wish to see the final answer on the paper, hit the * key and your answer will print.

If you are subtracting, let's say 100-40, you would enter 100 then + then 40 then - then *. Adding machines expect you to enter long strings of numbers to total. You may have both positive and negative numbers. So, you always enter the number first followed by either positive + or negative -.

You might have 100 + 25 - 37 - 1 + 50. For that enter:
100+25+37-1-50+ then *

Different than a calculator but the same for all "adding machines". This machine should really be called an adding machine since that is the kind of input it is looking for.

SOURCE: how do you subtract

Its a little strange. Suppose you want subtract 10 from 38. Do this:
Enter 38 press plus key.
Enter 10, press minus key.
Press the equal sign. You will have the result.

First, check the batteries, and ensure there is not a paper jam in the printer.
If both are fine, then while the calculator is in the "Print" mode, press the [CA] (or [AC]) button 20 times consecutively to clear out memory buffers. Try some numerical calculations, and if the problem persists, repeat pressing the [CA] button 20 times.
If the problem still persists, then the calculator may require service.

SOURCE: how to load paper in

Put the roll on the arms "like a toilet paper roll on the extender", and pull it under. There is a slot, slip the paper into this slot, and press FEED until the paper reaches the ink.

### What does the MU/MD key on the Casio HR-100TM do?

Here's how to use the MU/MD key. Say you want your item that COSTS you \$120 to be priced such that you end up with a 40% margin. MU'MD calculates the final price to achieve the margin.

Enter: 120 X
Enter: 40 MU'MD
Result: 200.00

Proof: 200 - 120 = 80 / 200 = 40%

Essentially the same as using the COST/ SELL/ MAR keys.

The Casio HR-100Tm manual is pretty pathetic. Expected a better one on their website, but alas.
