Page 57: Operating Your 7890 Scanner
Operating Your 7890 Scanner The 7890 Scanner Components The 7890 Scanner Components Before using your 7890 Presentation Scanner, you need to be familiar with some of its components. Figure 4-1 shows the scanner and identifies some of the parts and features.
Page 58: Presentation Scanning
Operating Your 7890 Scanner Presentation Scanning Presentation Scanning Presentation scanning is much different from that used at checkout stands, such as in grocery stores. In the checkout stand environment, normally large quantities of items must be scanned in a short amount time.
Page 59 Operating Your 7890 Scanner The 7890 Scanner Components Figure 4-2 Presentation Scanning (1 of 3) Position the bar code label completely within the red Laser Scan Pattern as indicated in Figure 4-3. Normally the bar code should be three to four inches from the scanner.
Page 60 Operating Your 7890 Scanner The 7890 Scanner Components Move the bar code label away from the scanner as shown in Figure 4-4. The scanner is now ready to read another bar code label. After not detecting an item for a period of time, the laser light turns off. To read another bar code, simply perform these three steps again.
Page 61: Pick-Up Scanning
In these circumstances you can pick up the scanner and take it to the merchandise. The 7890 Scanner includes a handle so that you can easily pick the scanner up and hold it. Being light-weight, you can present the scanner to the merchandise with little effort.
Page 62: Label Orientation
Operating Your 7890 Scanner Label Orientation Label Orientation Because your 7890 Scanner produces a dense, omnidirectional scan pattern, labels can be read from many different angles. In order for the scanner to read a label, the center 90% of Scan Pattern one scan line must cross the bar code.
Page 63: Label Rotation
Operating Your 7890 Scanner Label Orientation Your 7890 Scanner can read labels that are presented in Label Rotation many different positions. As shown in Figure 4-6, you can present labels that are rotated left or right 30 degrees from center, up or down 30 degrees from center, and 360 degrees around center.
Page 64: Distance From Scanner
Label Orientation For optimum reading, the distance that you must place Distance from the label from the 7890 Scanner depends on the density Scanner and height of the bar code. You can relate this to focusing a camera, where you change the focus setting based on how far away the object is.
Page 65: Read Indicators
When using IBM 468x communications, the Status Indicator flashes red (group of nine flashes repeated at 3-second intervals) when the 7890 is offline. This can be caused if the IBM host terminal has not established communications with the 7890, the host terminal is not turned on, or the interface cable is not connected.
Page 66: Indicator Functions
The details for programming the "Good Read Tone" are in Chapter 5, Programming Your 7890 Scanner. Your 7890 Scanner comes with the "Good Read Tone" enabled. As you move the bar code label into the scan pattern, Indicator Functions the scanner tells you if it is able to read the label.
Page 67: Bar Code Quality
The ability of your 7890 Scanner to read bar code labels depends greatly on the quality of the label. Although the 7890 can often read bar codes that appear to be bad, it cannot read bar codes that are obstructed, defective, or damaged.
Page 68 Operating Your 7890 Scanner Bar Code Quality The readability of a label depends on variables such as sizing, placement, color, paper type, ink viscosity, and package coatings. The middle of a printing run can yield erroneous labels due to the many variants involved.
Page 69: Taking Care Of Your Scanner
Also, totally avoid abrasive scrubbing or excessive cleaning agents. Your 7890 Scanner is designed to provide you with long, trouble-free service. However, it is up to you to care for your scanner. The following list identifies things you should consider in taking care of your scanner.
Page 70: Scanner Operation Summary
The scanner gives either a Good Read Indication or no 2 Observe the Read indication. A Good Read is indicated by the Status Indication Indicator going from green to red and then back to green. If the Good Read tone is enabled, the 7890 also beeps. 4-14 User’s Guide...

Page 92: Timers
Programming Your 7890 Scanner Timers Timers The Timers Programming mode controls the two 7890 Scanner timers: Lockout Time and Active Time. Refer to the Timers worksheet in Appendix A. The Lockout Timer prevents the scanner from Lockout Time repeatedly reading the same bar code. After reading a...
Page 93: Active Time
Programming Your 7890 Scanner Timers You can program specific lengths of time that your 7890 Active Time scanner stays on after the last good read. You normally want to pick a time that is long enough for the operator to pick-up and scan the next item of a sale. However, remember that you also want to minimize the amount of time the laser is on.
Page 94: Parameter Shortcuts
Programming Your 7890 Scanner Timers The Timers Programming mode contains four shortcuts: Parameter Shortcuts A, B, C, and D. After entering this programming mode you can go directly to a specific parameter by scanning the appropriate shortcut Hex tag (Hex A, Hex B, Hex C, and Hex D).
Page 95: Entering The Program
Programming Your 7890 Scanner Timers You can enter the Timers parameters in one of two Entering the ways. One is to enter all parameters, the other is to Program enter specific parameters using parameter shortcuts. Enter all Parameters In the Base Programming state, scan the Hex 1 tag followed by the Hex 2 tag.
