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.

Remove the plastic window where the paper comes up. See the printer ink roller on the right side. Lift it up and replace.

I am not sure what you mean. You computer has a built in software calculator. If your calculator has a USB port and is designed to connect to a computer (the Casio HR-100TE does not seem to have hat capability), you can use it as a numeric keypad. It would have a key to make what you type on the calculator echo on some number handling application like Excel.

On some calculators there is a key marked with K (on the key or around it on the calculator face).Try entering the divisor then the division key then press K. If that does not work try another order.On some other calculators you press the operation key twice. Try entering the divisor first then press the division key twice. The next number you enter will be divided by the one enter before pressing the operation key. (divisor).

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.

I get all of my stuff from Amazon. com. Sometimes Office Depot will have it, but you need to be SPECIFIC about which model you have

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.

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

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...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........

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....

Printing models (except HR-8TE): 1. Have calculator in ?print? mode 2. Press [CA] 3. Hold [SET/%] key for about 3 seconds 4. Input the tax rate 5. Press [TAX+] 6. Press [SET/%]

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

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.
