20 Most Recent Casio DR-T220 Calculator Questions & Answers

Put the roll in and feed the loose end up and actually all you need to do is put it between the two pieces of the hinge top. it is a thermal printer so it does not need to be fed like a regular calculator...it took me a few tries before I figured it out.

I ACTUALLY HAD A HARD TIME MAKING THEIR STEPS WORK. BUT WHAT I FINALLY FIGURED OUT WAS THE "FORMAT" WASN'T CORRECT. I WOULDN'T MOVE PAST THE DAY WHEN I WAS SETTING THE DATE. IT WOULD ENTER THE MONTH OK BUT THEN STOP AT THE FIRST DIGIT OF THE DAY AND WOULDN'T ADVANCE TO THE 2ND DIGIT. BUT WHAT I FIGURED OUT WAS THAT THEY WANTED THE DAY AND MONTH SWITHCED. SO INSTEAD OF ENTERING 07-29-2015 I HAD TO ENTER 29-07-2015 HIT TIME TIME AND IT WAS DONE. VERY FRUSTRATING BECAUSE THE MANUAL SAYS TO ENTER IT THE AMERICAN WAY 07-29-2015. ANYWAY, IT WORKED FOR ME. HOPE THAT HELPS. :o}

Below are the steps to assist you in
setting the Date and Time on your calculator.

NOTE: The "Time Set", "AM/PM", "12/24" and "Format" associated keys are
on the faceplate above the respective key. Position the calculator so
that you can look directly over the keypad to see the notations.

Setting the date:

1. Press the CALENDAR/CLOCK Key. The default date will appear.

2. Hold the TIME SET key down for 3 seconds or until you see the first
digit begin to blink in the display.

3. Input the correct date.

4. Firmly press and release the TIME SET key. The first digit should
stop blinking and the date is then set.

Setting the time:

1. Press the CALENDAR/CLOCK key. The default time will appear.

2. Hold the TIME SET key down for 3 seconds or until you see the first
digit begin to blink in the display.

NOTE: The seconds will disappear.

3. Input the correct time. If you need to adjust to AM or PM, press
the AM/PM accordingly.

4. Firmly press and release the TIME SET key. The first digit should
stop blinking and the time is then set. The seconds will again be
displayed.

Follow by pressing the CLEAR key to return to the calculator mode. To
return to either the TIME or DATE, press the CALENDAR/CLOCK key to
toggle between them.

Sir,
Follow the link below to download the user manual, you would need to identify the model number of your calculator.
The book will help you to do everything you need to do.
I can`t help you further because you didn`t identify the model number.
Good luck.

The Casio DR-T220 does not use regular adding machine tape, it requires a thermal tape since it is a thermal printer. There is no ink or ink ribbon in this caculator, it is heat activated and it is the special paper that make the numbers appear. Thermal tape is available at all office supply stores.

Turns out the incorrect type of paper was being used. The paper needed is the paper that is sensitive to pressure and this paper was not.

press the plus key again, it should work. ie put a number in and press the plus key twice, it should double, and again it should double again and so on

I have a model DR-T120 maybe it works the same way.

Try resetting the calculator. There should be a reset button on the underside of the machine. Press it with a pen and that should clear the E that is on your display.

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

Here is the Service Manual, but in normal instances, you would just buy another one, or return it to Casio for service.
