After you have added the shredder oil, you have to hold down the "Lubricate" button for about 5 seconds. This resets the counter and it will remind you to add oil when you have gone through about 250 more pages. Note: holding down the "Lubricate" button for 5 seconds will reset the counter and make the message disappear whether you add the oil or not, but it is highly recommended that you use the oil.

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.

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.

### Why doesn't the equal button work when I do additions and subtractions?

Your calculator is fine. It is an adding machine first, so it uses adding machine logic and you hit the star button to print the total on the tape. The equals sign is only used when multiplying and dividing.

Adding machine logic is as follows:

5+ total 5
3- total 2
7+ total 9
* print out total

Good luck,

### Why are totals rounding off

In the product details of this calculator, it states that there is a "decimal point selector." This is normally a slider starting with the letter F followed by the numbers 0123 etc. It is probably on 0. You can set the number of decimals to whatever you want, or use F for full numbers. For example, if you set this to 2, you should always get 2 decimals.

Good luck,

### How to install paper

Without a manual, look at the picture of the calculator. Mount the paper, with the feed coming forward and over the top of the calculator. Insert the paper (recommend cutting it flush) into the feed slot in the back. Then use the paper advance key to advance the paper through the rollers. Unfortunately the manual is not available from the Staples website. Good Luck,

### My calculator will add, but after my total and then I want to subtract, it subtracts by the number I added.

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.

### Tring to subtract

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.
