WHILE TRYING TO USE THE ADD-SUBTRACT MODE, MY CALCULATOR PRINTS ALL KINDS OF SYMBOLS AND STAGGERS THE PRINTING OF THE FIGURES. I HAVE THE SETTINGS AS FOLLOWS: DECIMAL +; ROUNDING ON LEFT UP ; GT OFF; PRINT ITEM. CHANGING ANY OF THE SETTINGS DOES NOT STOP THE CRAZY PRINTING OF THE SYMBOLS.

SOURCE: reset?

Okay, I did what the best solution did and worked with it.

"1. press 2nd F (left top corner)

2. ENG/FIX (the button next to 2nd F)

3. press 0 (if you don't want calculator to round off any decimals)"

In order to get your exact value of pi, in step #3, instead of 0, press the decimal [ . ]

This should give you no decimals when entering a number and give you 3.141592654... when you input pi.

Hope that works/helps.

As I added on to the previous solution on the other problem.

SOURCE: i cant make the decimal mode work (5000=50.00)

At the top of the keypad area, there is a switch with the following above it: +023F. Leave the switch in the + position and it should automatically place the decimal 2 postions, i.e. enter 5000 and the display will show up 50.00.

SOURCE: my calculator will add, but

If your calculator is more of an adding machine it works a little bit differently than a calculator. For an example: 10 + 5 - 2 on your machine do the addition of 10 + 5, then to subtract the 2 press 2 then the minus sign to get the total of 13. I hope this is helpful.

the function buttons are labeled + and -

to add put in the number then press the + button then put in the next number and + and son for all the numbers you are adding up

to subtract put in a number then press the- button ,then put in the next number and press the - button and so on

to do a combination calculation put in a number then press the + button and so on until you come to a number that you want to subtract in which case you put in that number then press the - button and if the next number is to be added ,put the number in and press the + button

The manual mentions an add mode, turning the calculator into an adding machine.

If this is the case, you can do this test and see if it works to confirm that it is acting like an adding machine.

4+

3-

5+

*

Think of these as integers. The 4 is positive, the 3 is negative, the 5 is positive. When we add all these integers together, we get positive 6.

Good luck.

Let me know if you have any questions.

Make sure it is switched to print mode. not just on.

With an adding machine, which is what this is, you enter the number followed by the + or -. If you wanted to add 10+20, you would enter 10 then + then 20 then +. This would show your answer. If you are using the printer and you wish to see the final answer on the paper, hit the * key and your answer will print.

If you are subtracting, let's say 100-40, you would enter 100 then + then 40 then - then *. Adding machines expect you to enter long strings of numbers to total. You may have both positive and negative numbers. So, you always enter the number first followed by either positive + or negative -.

You might have 100 + 25 - 37 - 1 + 50. For that enter:

100+25+37-1-50+ then *

Different than a calculator but the same for all "adding machines". This machine should really be called an adding machine since that is the kind of input it is looking for.

The asterix (*) next to the big fat plus key prints the running total.

Just figured that out. Why doesn't Canon have a downloadable manual for this thing?

First keep the manual aside .

From "columns of figures ",do u mean a set of calculations.If this is the case, if your calculator has brackets{ } or [ ] ,use this function to add or subtract columns of figures.

Eg: [789+546+123+852+6547+65]=8922

OR

[789+587+6598+458] - [ 548+2587+456+584]=

8432 - 4175 = 4257

I hope this solution solves your problem.

my calculator is printing odd symbols and will not print the correct total.

Same problem. Happened after I changed print cartridge. I put in a tech support email to Canon. Will respond back with answer once it is received. - Sue H.

Canon Tech Support never emailed so I called. They suggested to unplug the calculator wait at least 15 seconds them simultaneously press the reset button while plugging in the unit. This did not work for me and neither did multiple resets. Tech support suggested that the was something possibly wrong with the roller and suggested I send in for warranty repair.
