Taking the back off The Casio JF-100 calculator is similar to the ...TE. Remove the two screws at the top back. Place a small screwdriver blade along the seam where the back plate fits into the front plate. There are 3 fasteners on each long side and 1 fastener on each of the front and back sides. Find the spot where it's the easiest to separate the back plate from the top plate (there are only two). Carefully twist the blade to cause an opening. Then proceed sequentially around the perimeter releasing each fastener. The front plate will easily separate from the back plate at this time. There are no parts that will fall-out--don't worry. Replace the battery. Press the front and back plates together to snap the fasteners.

It is solar powred and will turn off by itself. Don't worry it doesn't cost anything.

If your Casio fx-991EX calculator is displaying [Dec], it means it's in Decimal mode. To switch back to normal calculations, press the MODE button and select the desired mode, such as COMP for computation or MATH for mathematical functions. I think this will solve your problem

The NEWYES NY-991MS and CTIFREE fx-991ES PLUS calculators do not have a dedicated "FACT" button like the Casio FX-83GTX. However, you can still find prime numbers on these calculators.To find prime numbers:NEWYES NY-991MS:Press the "MODE" button.Choose "PRIME" from the list of options.Enter the desired number and press "=" to check if it's prime.CTIFREE fx-991ES PLUS:Press the "MODE" button.Select "TABLE" or "TABLESET."Input a starting point and an ending point, then observe the table for prime numbers.Although the techniques may vary from those used on the Casio FX-83GTX, they prove to be effective for prime number calculations on the designated calculators.

Is there lights on, on the printer? Does it have a receipt paper roll in it? You can do a Power Cycle of the Terminal and the Printer. Unplug the printer for the wall socket. Remove the data socket, replace the data socket making sure the connection is tight. Disconnect the terminal from the main power, and count to 20. Plug the terminal back in. Now go to the kitchen and plug the printer back into the mains. The reset should fix it. The rest is in the manual, which I told you earlier today. Yes it is complicated and you may have a network switch if you have multiple terminals and possibly a computer joining everything. If you find that too complicated, call the company that sold you the unit and tell them to bring a new ticket printer with them 'just in case'. That type if ticket printer is fairly specialized, but they are common. They normally don't charge for that type of help In the manual under Remote Printer Control. https://totalpos.co.nz/wp-content/uploads/2020/03/QT6600-Reference-Manual.pdf More here https://www.google.com/search?q=Casio+QT-6600+connect+kitchen+printer ..

Yes, the Casio fx-991EX scientific calculator has a feature called "natural display" which allows you to input and display mathematical expressions exactly as they appear in textbooks, including variables such as "x".

To perform the calculation you mentioned, 2x * 2 = 4x, simply enter the expression "2x*2" into the calculator, and it will display "4x" as the result. You can then use this result in further calculations without having to enter a value for "x".

To enter the variable "x", you can use the "ALPHA" key followed by the corresponding letter key. For example, to enter "x", press "ALPHA" followed by "X".

Note that if you want to solve for a specific value of "x", you will need to use the solver or equation mode on your calculator to input the equation and specify the value of "x" you want to solve for.

To load paper into the Casio DR-T220 thermal printer calculator, follow these steps:

1. Open the printer cover by pressing the release button located at the front of the calculator.
2. Carefully insert the roll of thermal paper into the printer with the paper facing forward, and the end of the paper coming out of the top of the roll.
3. Adjust the paper guide to fit snugly against the paper roll.
4. Close the printer cover.
5. Turn on the calculator and press the "Feed" button to advance the paper to the correct position for printing.

Please Note: Be sure to use the correct type of thermal paper for your calculator, as specified in the user manual.

The "syntax error" message that you are seeing on your Casio fx-991EX ClassWiz calculator is likely caused by the fact that the calculator does not support the use of decimal values in the exponent. The calculator can only accept integers (whole numbers) as exponents. To work around this issue, you can try rounding the decimal value of the exponent to the nearest whole number. For example, if you need to calculate 1x10^7.2, you can round the exponent to 8 and calculate 1x10^8 instead. This will give you a close approximation of the desired result. Alternatively, you can use a different calculator or software that does support the use of decimal values in the exponent. This will allow you to calculate the value more accurately.
