# Calculation vs. print-out error

Calculates correctly, but prints completely different numbers than what's on the screen. Also, on a different calculator of the same version, I can't get the red ink to work when using doing a subtraction calc and it prints black dots all over my paper.

It has a little ink roller under the plastic on the right side as you are looking at it. It is made of black plastic and pulls straight up to come out

SHARP EL-1801V DON'T KNOW HOW TO SET THE DATE AND TIME

Posted on Jun 12, 2008

i had a problem with this as well and found a user manual online. I thought the whole thing came out but it doesn't. If you pull up on the little red thing on right and then the black one on the right you have it. Imagine that! That's all that you change. Then just put some new ones in and your good to go.

SOURCE: how to calculate

It's very simple: the calculators have a default base 10 so that log x it's log x base 10 so here is some logs:
log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y
Hope it's helped

Yes look you can't enter the base in calculators it's default 10 so use:
log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y
so instead of log 8 base 2 input log 8 / log 2 it's easy
hope you understand :)

### I am using a Casio fx-9750GII, when I try drawing something, it says range error. How to fix and I need to know WHAT the numbers should be set to.

That's something we can't tell you, Paige, until you tell us exactly what calculation you're using to draw on the screen. You can't just throw numbers at it in hopes of drawing something, its purpose is to show you what a calculation looks like graphically so you can better visualize your results or predict the results of a subsequent calculation. It's not built to be a toy, it's built to be a working tool.

### Can't find a manual online. What does 5/4 mean, and how do I turn it off? Same for E. My biggest problem is that when I add up numbers with the print function on (for depositing large batches of...

The manual for the Canon P1-DHV is online at http://www.usa.canon.com/app/pdf/calculator/P1-DHV_G_USA_HWB.pdf>.
When the display shows "5/4", the calculator is doing 5/4 rounding which means: 5 or above round up, 4 or below round down. To control rounding press the "5/4" key.
When the display shows "E" the calculator could not complete a calculation. It can be because of dividing by 0, or because the total exceeded 1 trillion, or because the operator entered calculations faster than the calculator could complete them. Press the CI/C key to clear it.
I can't explain why you are not getting a total on the tape. Try the following example from the manual exactly as shown, and let me know if your tape shows the total.
1. Clear the calculator (press [CI/C])
2. Choose 5/4 rounding (press [5/4] until "5/4" displays)
3. Choose add mode (press [DEC] until "A" displays)
4. Choose cost-sell-margin mode (press [B-T] until "B" displays)
5. Turn printer on (press [PRINT] until "PRINT" displays)
6. To calculate: \$12.55 + \$15.75 - \$5.30
7. Key in: 1255 [+] 1575 [-] 530 [=]
8. Tape shows: [0. C] ... [12.55 +] ... [15.75 -] ... [5.30 =] ... [23.00 *]

### THE CASIO HR-100TM HAS AN E ON THE SCREEN AND THEREFORE I CANNOT USE TH MACHINE. HOW DO I REMOVE THE E

First, check the batteries, and ensure there is not a paper jam in the printer.
If both are fine, then while the calculator is in the "Print" mode, press the [CA] (or [AC]) button 20 times consecutively to clear out memory buffers. Try some numerical calculations, and if the problem persists, repeat pressing the [CA] button 20 times.
If the problem still persists, then the calculator may require service.

### Printing error

the problem is with the printer. try to examine if the printer head is on the right side. the default must be on the right side. if you can't move the printer head towards the right it means it got stuck up. if you will look inside it you will see a 'rail like' object on the bottom of the printer you can push it down with any pointed object for the pinter head to get back to its original position. if this doesn't solve the problem look for the nearest service center coz the printer needs an alignment.
