Question about Sharp EL-1701C Calculator

"P" appears on screen

At random, during calculations - plus, minus, equal, anything - suddenly the letter P appears in the window. I have to total the calculation out and start over. Is there a way I can stop it from doing this?

    I also have the problem with the P appearing on screen during calculations.I am very frustated with having to total the column and start over again.

    The screen has P.E locked I can't get anything else. I have used the reset button on the back, pressed the 2nd button M+, M- and just about every combination possible

    Like everyone else. The P appears in the middle of a calculation. I think the current solution posted may be correct. I've tried to loosen the screws to no avail...paobably because they're too tight.

    Have had this problem since I bought the calculator. Should have returned it!

    The "P.E" appears only in the "print" mode! The manual suggests that there is a paper jam, However, this problem occurs even if the paper transport is free, loose and clean without any jam inside the rollers or transport system.

    I loosened, re-thightened the backside mounting screws as suggested elsewhere, but without success.

    I'll gladly fax a copy of the manual, should anyone has a need of it. (...If the requests are not overwhelming).

    same problem "p" appears after entering a few numbers.

    I used this calculator for two years without this problem occurring.

    I loosened the screws on the back of the calculator but that did not help.

    I was thinking maybe my batteries were low. I then removed the batteries and put the same batteries back in. Turned on the calculated and it kept revving so I hit the "reset" button on the back to make it stop. This turns the calculator off. I then turned the calculator on and it has been working fine ever since.

Well , I've been having the same problem for a while now. I tried taking out the screws but they were way too tight so I tried the oldest trick in the book. I banged it up a little and so far everything seems fine!!!

Did that and the P still shows up.

Thank-you so much!

I had the same problem and was going to buy a new adding machine but I did a quick search and found your website.

I loosened the screws (which seemed loose already) on the bottom but the "p" came up almost immediately.

Next I tightened the screws up and voila!! It works!! The problem was that the screws had loosened up during years of use.

Try loosening the screws on the back. On ours they were installed too tightly, probably pinching something inside and causing the P to appear at random.

The ribbon will only print red ink

While in the D position or PD position, N Count
is OFF. In the N Count N position every
Plus, Minus, Equals Plus, Equals Minus,
Memory Plus or Memory Minus key depression
is counted. The Accumulator and its N Count
or the GT N Count can be printed by
depression of the Subtotal or Total key. When
either Memory Subtotal or Memory Total is
depressed, Memory N Count will print. N Count
is always printed in red, left justified. If the
Equals key is depressed immediately after the
Subtotal Total, Memory Subtotal, or Memory
Total the average of the entries is printed.
When the N Count prints on the 7150, an audit
symbol will print to the left of the N Count.
The audit NA will identify the Accumulator
register N Count, NG will identify the GT
register N Count and NM will identify the
Memory N Count.

How do i use the equal sign when solving an equation?

You enter the problem into the calculator and when you are finished you press the equals sign to make it give you the answer to your problem.

Here is an example;

If I wanted to know what the sum (or total) was for 2 + 10+ 16 - I would enter the number 2 and then the plus sign + and then the number ten and the plus sign + and then the number sixteen and the plus sign again + and then press the equals sign which looks like this =. when I press the equals sign = the calculator gives me the answer to my question of what the total of those numbers are.

I hope this helps?

How to graph y=-5/2x-2 on ti-84 plus calculator

Press Y= (the key at the very top left, above the blue 2ND key). On the Y1= line, enter (-) 5 / ( 2 X ) - 2 if the function is "negative five over 2x minus 2" or (-) 5 / 2 X - 2 if the function is "negative five-halves x minus 2".
(The (-) is the key to the right of the decimal point.) Then press GRAPH (the very top right key) and the graph should appear. You can press WINDOW (just to the right of the Y=) and change the window settings if you wish.

If this doesn't do it, post a comment and we can go from there.

Its a little strange. Suppose you want subtract 10 from 38. Do this:
Enter 38 press plus key.
Enter 10, press minus key.
Press the equal sign. You will have the result.

How do I get this calculator to substract

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.

There is no "plus equal" key!

press the plus key again, it should work. ie put a number in and press the plus key twice, it should double, and again it should double again and so on
