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.

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).
Good luck!

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.

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.

You need an IR40T Ink Roller

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.

Couldn't find a manual or user guide. The closest I got were two pages, one with the calculator, and one with the group of calculators that explains some of the functions.
