20 Most Recent Casio HR 100TM Portable Printing Calculator Questions & Answers

Once you enter your number like so (5.00 press (+) 11.00 (+) 5.00 (-) then press the *key, should be bottom key next to + = key). Hope this helps, sorry to be so late with an answer.............

The ink supply is a small roller. Remove the clear plastic cover over the (printed) paper and the roller will lift out. It only takes a couple minutes to do the job. I suggest not wearing anything white as you will probably get a little ink on your fingers.

Move selector switch to (add 2) then when you enter a number it aumatically insterst decima. Example enter 1234 and it will print out, 12.34

Try clean the tiny black roller in the back of the black plastic (see picture). It doesn't pick up the paper when it's too dirty and dusty. I wetted a tiny piece of paper towel with alcohol, pressed it on the roller and pressed the "feed" button so that the roller spins and gets clean up. Hope it helps.

What model is the calculator and if it's a inker type then you have to replace the ink roller. If it's the ribbon type then you have you replace the ribbon. You can pick those inker or ribbon from Edmonton Cash Register Co. Ltd. or send us a email to order

The E is an indicator that the Paper Spool is EMPTY so either the paper sensor is defective or You have forgotten about a "bar" that the Paper must go through to be sensed. Or Your Feed motor has fed it's last. Best of Luck!

Press the CA button twice. Then push and hold down the %/set key until the 0 disappears 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. Posted on Feb 25, 2008

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
