• IT4410/4710: Hold the imager 5.0 in (12.7 cm) for LR models, 2.0 in (5.1 cm) for the HD, and 7.0 in (17.8 cm) for the LX from the bar code symbol. This distance is measured from the imager's front window to the reading surface.
• The hand-held imager has a view finder that projects a bright aiming beam that corresponds to the imager’s horizontal field of view. The aiming beam should be centered over the bar code and positioned horizontally over the code (no tilt, skew, or rotation). If the symbol surface is shiny, the reader may have to be held several degrees below the normal position to avoid specular reflections.
If one or more of the measured parameters fail to meet the MAG, the PQA message is also sent with a beep. Note: With the IT4410/4710, screening mode outputs are also accompanied by a single beep if all parameters are okay or a triple beep if one or more of the measured parameters fail to meet the MAG.
If your imager is in keyboard wedge mode, enable Screening by scanning the following bar codes. Minimum Acceptable Grade = A Minimum Acceptable Grade = C You can exit both Full Report and Screening modes by either typing the menu command, 2D_PQA0, if you are using Quick*View, or by scanning the following bar code: Identifying Symbol Content...
While the details are explained below, this general format includes: • the encoded data (the usual output message) in the first line. • a banner " >>> PQA from HHP <<<" identifying the start of the 2D PQA report. • the symbology, its features, and approximate size.

{5} [A] < Row Height = 3.1 X {6} [A] < Useful Row Height = 2.5 X (82% Row) {7} [A] < Data Safety Margin = 100% (0 Erasures & 0 Errors) {8} [B] < Edge Accuracy = 59% {9} [C] < Print Growth = -43% of X where: {1} is always the Encoded Message, the usual data output.

if Useful Height >= 1.0 X, else otherwise In Screening modes, this parameter is reported as "Useful Row Height is Too Short (1.5X)" when that is the case. {7} lists the Data Safety Margin, which is the ratio of the unused error correc- tion words to the recommended (!) number of such words.
In rare instances where neither a valid Start nor Stop pattern is measurable, yet the symbol is somehow read, lines {8} and {9} are replaced by a message to that effect. The message is either: "[F] < Start/Stop Decode Fails" in a Full Report or "Start/Stop Characters are Bad"...
if Row Height >= 1.5 X, otherwise. {6} lists the Data Safety Margin. Because MicroPDF's error correction level is fixed, this parameter is just the "Unused Error Correction" and always between 0 and 100%. {7} lists the Edge Accuracymeasured in multiple scans through the Row Address Patterns.
Note: The reported X-dimension is approximate and based upon use of the IT4410LR at 4.7 in (12 cm) (see "Reading Techniques" on page 1-1). If you use different image engines, the X-dimension will vary. If you hold the reader closer than 4.7 in (12 cm), it will have the effect of reporting a larger than true X-dimension.

{7} [A] (Ok) < Bar Widths = 0.022 in. {8} [A] (Ok) < Inter-Bar Gaps = 0.023 in. {1} is the Encoded Message. {2} is the Banner heading. {3} identifies the Symbology, (POSTNET or PLANET Code), and lists also the symbol's size and allowed range of measured width.
4-State Codes The Full Report from a typical scan looks like the following (line numbers have been added in curly brackets): {1} B15AJ6T >>> PQA from HHP <<< {3} 4-STATE(British): 34 Bars, nominally from 38.5 to 42.3 mm. in Width {4} Bar Sequence: ADHTATDAHDDAADADAADTHTADHHDATHTADH {5} [A] (Ok) <...
Note: For the Canadian and Australian 4-State symbologies only, any bar error that has invoked their error correction triggers an additional PQA parameter line: "[F] < One or more Bars are in Error!" in a Full Report or "One or more Bars are in Error!" in a Screening mode. Table 1: Dimensional Tolerances for the Various 4-State Bar “Tall”...
Bar Sequence Bar Sequence is the bar height pattern within a height modulated, multi-state, postal-type symbology. In a 2-state symbol, a "1" represents a tall or full height bar and a "0" represents a short or half height bar. In a 4-state symbol, "A" rep- resents the ascending bars, "D"...
Encoded Message The encoded message is the information (alpha, numeric, and/or control char- acters) or message contained within the bar code symbol and output as part of the decoding process. This information precedes the calculated PQA parame- ters. This information must be manually compared to the characters that should be encoded.
Module Errors Module Errors are individual errors within fixed pattern/data areas. Although often benign, Module Errors in the fixed regions of a symbol can signal a fault that, in some instances, will prevent proper decoding. They can generally be corrected by using a larger X-dimension and/or cleaning up the print process to eliminate stray ink, voids, and other causes of inconsistency in the print.
height, giving more leeway to symbols printed with above minimum row heights (e.g., 4.0 X). A poor grade here is corrected by either stretching the symbol ver- tically or correcting the print condition (e.g., turning down the thermal burn set- ting or adjusting inking) that causes rows to interfere.
Quick*View Quick*View Demonstration Software Instructions Quick*View is a Microsoft Windows messages and captures images (for instance, ID photographs) from the imager. Bar code information and images are displayed in the Quick*View window. Note: For additional information about Quick*View, please refer to the user’s guide for your imager.
Note: If you have a unit capable of keyboard wedge mode, scan the bar code below. The unit will communicate in RS-232 mode, allowing it to work with Quick*View through an appropriate serial cable. To convert the imager back to keyboard wedge communication, cycle the power. IT4600/4800/4X80 IT4410/4710 2 - 2 Quick*View Quick*View...
Using the Quick*View Software Upon startup, the Quick*View splash screen appears for approximately three seconds. Quick*View will then attempt to establish communications with the Imager. If Communication Cannot Be Established This message appears if communication cannot be established: Quick*View defaults to com 1 as the communications port. If you have plugged the Imager into another com port, you must Cancel out of this message.
Scan Data Window Once successful communication has been established, you can scan codes and display the bar code data in a window. Select View - Scan Data Window. As you scan bar codes, the data appears in the Serial Scan Data Window. You can alter the font in this window by using the Font button, or clear all data in the window with the Clear button.
