Question about HP scanjet 3970 digital flatbed scanner

I'm trying to get on-line help with my HP Scanjet 3970 Scanner but to do so I need the Serial Number - and I can't find it anywhere. Would anyone know where it is or where I can find it, like on my computer?

Thanks a lot -

Billy

The 10 character serial number and the product number are located (on my 3970) on a sticker on the inside of the cover.

You can verify that you have the correct numbers if you enter them at

http://h20000.www2.hp.com/bizsupport/TechSupport/WarrantyLookup.jsp?lang=en&cc=us&prodSeriesId=298547&prodTypeId=15179

That will tell you if they are the wrong numbers as well as the warranty status of your scanner.

Do you want combinations or permutations? They're different things. A combination of n items taken m at a time, sometimes written "nCm", selects m items from a group of n without regard to order. A permutation of n items taken m at a time, sometimes written "nPm", selects m items from a group of m with regard to order.

Given six numbers, there are six combinations of one number, 15 combinations of two numbers, 20 combinations of three numbers, 15 combinations of four numbers, six combinations of five numbers, and one combination of six numbers.

Given six numbers, there are six permutations of one number, 30 permutations of two numbers, 120 permutations of three numbers, 360 permutations of four numbers, 720 permutations of five numbers, and 720 permutations of six numbers.

What do you want Darrell?

Code reader or Professional scan tool?

I think your going to need a shop to work on it

Without wiring diagrams your done

You have to chase every wire from the under dash

connect to their ends, until you fix the issue & can

connect to the Bus & Data stream,we can't help with that

Use the words: decimal part, not decimal fractin

**Any number whose decimal part is periodic (has a recurring pattern that repeats indefinitely) is equivalent to a rational number, IS a rational number**

0.345 345 345 ... =345/999=115/333

In the following screen captures, discard the last digit if it does not belong to a period. It is the effect of rounding up of the calculator

**Period is 345**

**Period is 1**

Period is**09**

Period is** 79**

In general, if you have a decimal part of the form 0.d_1 d_2 d_3....d_n d_1 d_2 d_3 ...d_n ... where d_1 is the first digit of the period, d_2 is the 2nd digit of the period, ..., d_n is the n-th digit (and the last one) of the period, then the fraction representation of

0.**d_1d_2...d_n** d_1d_2... d_n ...=(**d_1d_2...d_n**)/(99...9) where the number of 9's in the denominator is equal to the number of digits in the period.

Once the fraction is found, one should reduce it to its simplest form.

How does the bulb look? Is it bright or kind of dim. The bulb warming error is designed to halt use of the machine until the scanner bulb reaches the correct output level. As these are basically a flourescent tube, they will dim over time and at a certain point they will not generate enough light to enable proper scanning. If the bulb is dim, it will require replacement.

Using the 1515 as a fax machine is a pretty simple procedure if everything works right. All you have to do is hook a working phone line up to the phone jack on the back of the copier (the one labeled LINE, not TEL).

Why won't the fax work? If it is giving you an error message, what is the message?

If you are not getting a dial tone when faxing, unplug the fax from the phone line and plug a working phone in, and see if the phone gets a dial tone. If it doesn't, there is a problem with your phone line.

You can also try plugging the fax machine into another phone line. If the fax works on that line, then there may be a problem with the first line.

Are you having problems sending faxes or receiving them, or both?
