When i hit the x,t,pie,n key, it comes up as pie. i need the x variable to come up. how do i change that?

Step 1:
What sort Of stuck ?

A stuck key on a keyboard is one of those annoying things. The typical desktop keyboard has about 104 keys, a laptop keyboard has a few less. The problem of a stuck key can be a hardware or a software problem or the key itself might be the culprit.

Hit the key several times. This will almost always unstuck a key. Clean the keyboard with an approved keyboard cleaner. These often come as wipes. People sometimes spill food and drink that can make keys sticky. Pop the keys out using a small knife or flathead screwdriver. Most keys pop right out and can be pushed right back in place. Look for something that might be blocking the key and remove anything you find.

To convert a symbolic result to numeric, press diamond then ENTER. To have all results come out in numeric form, press MODE to bring up the mode screen, press F2 to go to page 2, use the arrow keys to move to the Exact/Approx line, press right-arrow, select Approximate. Press ENTER to save the change and exit the mode screen.

it sounds like your hitting the secondary key button and just putting in letters you should use x on variables button substitute other letters your using for x (sorry i couldn't make this much clearer)

The calculator is set up to produce exact results. If you want the expression to be evaluated put a decimal mark at the end of the 4.
to making 4 a floating point number instead of integer.
Alternatively, press the [MODE] key. Scroll down through the pages of options until you reach the line labeled Exact/Approx. When cursor is on that line, use the right arrow key to open the menu. Select [3:Approximate]. Press [ENTER] to save.

Hi you can try this.

To reset waste tank full error in MP730.

1. Hit the "menu": Key
2. Hit "Copy" Key
3. Hit "#" Key
4. Scroll thru the menu headings until you come to "Test Mode" - 12th heading
5. Hit the "3" button- this will bring up Eprom Clear
6. Hit "0" button
7. Hit the "Stop" button

Can only try then your printer go on longer but some time the other you need to clean out the waste ink it inside the printer go to open up all.



Please come back and just gave a vote, it will gave me some satisfaction to know am helping some one so I will keep on helping.

No you don't have to download a interpolations program, you can enter it in as a function like this:

:dp(xx1,yy1,xx2,yy2,x)
:Func
:yy1+(yy2-yy1)*((x-xx1) / (xx2-xx1))
:EndFunc

How I do it is, I put it in a folder dc so, you create a folder name dc

2nd key then - key which will be the VAR-LINK key
hit F1 key then the 5 key to create a new folder. Type in what you want to call your folder in my case dc and hit enter.
Next,
Hit APPS key then 7 key then the 3 key, then you see the word program highlighted open it up and change to Function hit enter.
Then slide down to your new folder you just created in my case dc, once you find it highlight it and hit enter.
Next,
slide down to variable and type dc and hit enter.
Next, type in or make it look like this:

:dp(xx1,yy1,xx2,yy2,x)
:Func
:yy1+(yy2-yy1)*((x_xx1)/(xx2-xx1))
:EndFunc

Now when I'm at the home screen in the main folder, I type:
dc\dp(0,0,5,100,2)
And I get 40 for my answer.
Here's my logic:
0,0 is the starting point, let's say my circuit max voltage is 5 volts and my max resistance is 100 ohms. I want to interpolate or know how many ohms I would have if my circuit measured 2 volts, which is 40 ohms.
Now if I had ohms and wanted volts I just set it up like this:
dc\dp(0,0,100,5,40)
which equals 2 volts
i hopethis helps you. raklein62

change the mode to stat and then start operating it in statistical mode

try clearing the memory of all the variables..that might solve the problem mohit

goto home and type Define x
