Re: letter G appear at the end of barcode
You have a "suffix" programmed into the barcode scanner. this is a common feature and allows for auditing (like a user signature) these can be removed, The code book should have pages of option programming barcodes, in which you should be able to find a section on programming prefixes and suffixes, there should be a control barcode which clears all suffixes. This should solve your problem
A 6ya expert can help you resolve that issue over the phone in a minute or two.

<p>Placing barcode equipment or other things makes it easier to
keep track of them. Instead of entering a long number, a quick scan with a bar
code reader eliminates keystrokes. There are many
different types of barcodes. The most famous is the Product Code or UPC
Universal, in almost all items sold at retail in the United States. The UPC
format only supports encryption of the songs. Other formats such as Code 39
(also known as Code 3 of 9) support letters and numbers. <br />
<p>1. Find a free TrueType font to the desired shape of the bar
code. For example, the Code bar code format is 39 different TrueType font
packages available free. Use an Internet search engine and type "Code 39
TrueType fonts" available in a free font found. Some specialized formats
may not be available for free as a result of copyright or other restrictions. <br />
<p>2. On your Windows PC, select the Start menu and click
Control Panel. Within the Control Panel, click Switch to Classic View "and
appearance of the panel. Find the" Fonts "icon and double click to
open it. On the File menu, select" Install New Font. "This opens a
menu dialog asking you to change the font to install. Navigate to the folder that
contains the downloaded TrueType font file. Select the font and click OK when
prompted to install it. The source of new bar code will be available in Excel. <br />
<p>3. Start Excel and enter "98765" in cell A1. This
value is converted to a bar. <br />
<p>4. In cell B1, type the following formula: "=
CONCATENATE ("*", "*")" A1 and press enter. The result
should be "* 98765 *". Code 39 format requires an asterisk at the
beginning and end of the text to be encrypted. Bar code format other will have
different rules. <br />
<p>5. Change the font in cell A1, choosing a different font
from the drop-down menu at the top of the screen in Excel. Under the menu
"Home", scroll down to "three of the nine free" source and
select it. The text in the cell will now appear as a barcode. Increase font
with a minimum of 28 points, so a scanner can pick up the scanning needs. <br />
<p>The primary purpose of bar codes is to encode the unique
characteristics of numbers and letters can be in a format that machines can
easily read. However, bar codes are read by people often also for this reason,
the codes generally include both parties readable and legible. The most popular
bar codes meet a standard called "Code 39". The latest version of the
code with 39 additional characters called "Extended Code 39." Among
other characters, Extended Code 39 allows users to include carriage returns
(CR) in bar codes. <br />
<p>1. Setting the bar code scanner to read "Extended Code
39," Code 39 is not as common support CR. The details depend on the
specific bar code scanning software is used, but you will usually find this
option under "Tools" then "Options." <br />
<p>2. Configure the software to generate bar code to the
"Extended Code 39" is also used. The details depend on the specific
software to generate barcode is used, but you will usually find this option
under "Tools" then "Options." <br />
<p>3. Type "M $" (without the quotes) at the point
where you want the CR model is within the barcode. M $ gives a CR Extended Code
39. <br />
UPC=Universal Product Code
The UPC encodes 12 decimal digits as SLLLLLLMRRRRRRE, where S (start) and E (end) are the bit pattern 101, M (middle) is the bit pattern 01010 (called guard bars), and each L (left) and R (right) are digits, each one represented by a seven-bit code. This is a total of 95 bits. The bit pattern for each numeral is designed to be as little like the others as possible, and to have no more than four consecutive 1s or 0s in order. Both are for reliability in scanning.
Since S, M, and E all include two bars, and each of the 12 digits of the UPC-A barcode consists of two bars and two spaces, all UPC-A barcodes consist of exactly (3 × 2) + (12 × 2) = 30 bars.
The UPC has only numerals, with no letters or other characters. The first digit L is the prefix. The last digit R is an error correcting check digit, allowing some errors in scanning or manual entry to be detected. UPC data structures are a component of GTINs (Global Trade Item Numbers). All of these data structures follow the global GS1 standards.
you can use the suffix or prefix to send characters, which are not included in the barcodes tgehter with the scanned barcode data.
If you dont need any character before or after the data, you can leave it blank.
It is usually used to add an Enter or Tab to switch to the next line, while scanning to some application like excel.
In general you can create an Advanced Data Programming Rule which will say: If you scan an UPC barcode, please send only the first 11 characters of the barcode.
There are programming barcodes in the manual for the scanner or you can use the 123Scan2 application provided at support.symbol.com to create the rule and print out an config sheet.
Hello paul blando. I think I can help you here. First, are you sure your barcodes with asterisks are Code128 like the others? Generally a Code128 barcode will look like: "(1234) 567890 (01) 123456" and wouldn't really use asterisks at all. However, I know that it is standard practice for people who make their own Code39 barcodes to start and end the code with an asterisk to denote a start/stop action. Could they be Code39? They would look like: "*123456789*". If this is the case, then I have the manual for the P370/P470 on my company's site here. Take a look at the Code39 Chapter and make sure to print and scan the pages to disable the check-digit transmittal. If that doesn't do the trick, then try the "recall defaults" or "reset to defaults" barcode to reset the scanner to it's initial defaults. That should put it on track. If you still have trouble, please feel free to send me a message or email me. I hope this helps. Good luck!
Be sure the Flic scanner is set to the factory default configuration by scanning the Defaults bar code given above.
Then check the Format options for Characters to Strip and Characters to Append (see page 10) and make sure these are set correctly.
In order to scan the ?Factory Defaults? bar code in the Flic Operator?s Guide to reset your Flic scanner to the default settings: Select Flicware , Tools , Format and add the appropriate control character(s) in the Characters to Append box.
