How to use the subtotal function on Casio HR-100TM

Big calculators work a little different than handheld calculators. Like the above commentor explained, if you have a basic "whats 100 minus 20?" You have to entered as 100 + 20 -- And when you hit the minus button at the end, it will give you the total. 100 is the positive number, and the 20 is the negative number that your subtracting. Also you can hit 20 -- 100 + and get the same total because you entering 20 as the negative and 100 as the positive, just in reverse.

I was able to order the part I needed at Americanperfit.com

Thanks

100:25 = 4
What?! Am I doing your homework. Should you be using a calculator for this?!

Hi...This calculator takes a IR-40T ink roll.
Turn off the power.
Open the top cover,
There is a flat tab on the ink roller, lift up, remove.
Hold the new roller by the tab, line it up in the slot and snap in.
Turn on the power and test.
If it doesn't work you might not have it snapped in properly or all the way.
Good Luck........

1. Remove the top gray lid of the calculator
2. Insert paper through the back side slot near the power charger
3. Turn the calculator on print
4. Press FEED a couple times

Its probably worn out. I have been messing with mine and if it does feed it is slipping and overwrites.

use air can from radio shack and use dry cleaning spray while you press the button many times

The problem of your unit is its printer. Probably the gears has misaligned. Only an authorized technician can align the printer of that unit, because it is a bit difficult to align the gears.

Try to contact the nearest service center of casio in your area.

HI..if this is a printing calculator and the print mode is turned...if there is a problem with the printer and E for Error will appear. The ribbon or some paper could be jammed in the printer..a key could be stuck down..check your entire keyboard key for sticking.
The calculator wont hurt itself and that is why the E is on. Examine it very carefully and look for something caught in it.
If none of the above you might have to get a pro to look at it.
Hope this helps you out....

The way to do it is this; Divide the number by 2, get the integer quotient for the next iteration. Get the remainder for the binary digit, repeat the steps until the quotient is equal to 0.

It is because it is not set up correctly. For you to fix it, just press on the lower right button for few seconds till it displays " cas10" then let go of the button
