Scanners

Document Scanners

High-Speed scanners are production model scanners which are adequate to scan the daily work load of the customer and may also have capacity for back-scanning of the customer’s existing files. The scanners operate mostly in an unattended mode because of smooth paper feeding and automatic features such as double-feed detection, LED panel controls and paper jam audible alarm. The scanners are relatively maintenance-free usually requiring changing the feed rollers (replacement roller kits) after 500,000 pages or so. Major savings include reduced paper consumption, copying costs, file storage costs and labor costs.

Value-Added Testing & Scanner Installation

When you purchase a scanner from KeyNet, it is thoroughly tested at KeyNet before it is shipped to you. KeyNet provides the results of this testing in the form of a Scanner Installation Guide. These documents provide information on how to install the scanner drivers, differences between operating environments, and other details about the proper operation of the device.

KeyNet’s Tips for Production Scanners

Connecting a new scanner to computer system can be a simple and intuitive task. Unfortunately this is usually the exception rather than the rule, and when problems do occur, it is often difficult to determine origin of the difficulty. Our technical bulletins present a methodical approach to scan driver troubleshooting.  Some low-end scanners use the EPT port, and USB devices are becoming more common, but in most cases you will be dealing with a SCSI scanning device. Understanding a few things about this interface will help you avoid most of the common problems.

RESIST TEMPTATION TO TRY ‘LOAD AND GO’

When you purchase a new scanner, especially if it is a high performance device, there is always the temptation to plug it in, install Setup from the CD and try it out. Sometimes this works, but USUALLY it ALMOST works, leaving you with the impression that you have a problematic device, software or both. If you resist that temptation, and methodically satisfy some basic requirements, your new scanner’ experiences will be consistently error-free, and you’ll save a lot of time and frustration.

SCSI ADAPTER

KeyNet recommends Adaptec SCSI Adapters. The AHA2930 is a high quality adapter and is relatively inexpensive.  When a SCSI adapter is seated firmly into a PC, your system you should see a test message from the SCSI adapter which indicates that the adapter has been recognized and acknowledged by the computer. SCSI devices must be assigned a SCSI ID. This assignment is made either through a physical switch on the scanner, or through a scanner control panel setting.

CABLE

The SCSI cable that connects the computer to the scanner is the next challenge and worthy of consideration. Make sure your cable was supplied by a reputable vendor, and is not over 6.5 feet (2 meters) in length. Check to ensure that the cable is connected properly and firmly at each end. Make sure the cable is not under excessive stress either by stretching or bending. SCSI cables tend to be fragile and should be handled and connected carefully.

SCANNER

There are a couple of things you need to know about the operation of a SCSI device. First, make sure the scanner is powered ON before you apply power to your computer. If the SCSI device is not powered ON first, it will not be recognized during the Boot process.

EZSCSI/ASPI/WINASPI DRIVERS

Your adaptec card should have come with a CD or diskette containing drivers for the specific adapter you are using, and for the specific operating system. For example, there is a Windows NT EZSCSI driver for the Adaptec 2930 card. No other driver will work so make sure you have installed this driver properly.

RECYCLING SCANNER POWER

Some Scanners (particularly the Fujitsu brand devices) require a power-down/power-up sequence after drivers have been installed, or re-installed. Since it does no harm and could resolve problems using the scanner, we suggest, as standard procedure, that you recycle power to the scanner and then reboot your system whenever you have installed new scan drivers for a device.

TEST THE SCANNER USING THE PROVIDED SCAN UTILITY

If you have booted your system and seen the scanner included as a listed SCSI device, and have been able to successfully install the ASPI and TWAIN drivers you are now ready to test the scanner with the software shipped with it. Start the utility application and select the TWAIN mode. Then attempt to scan a few pages. If this utility does not work, one of the above steps has not been done properly, or the scanner is incompatible with the operating platform.

USING THE SCANNER WITH CO-STAR

Once you are sure the scanner is working properly with software shipped with it, you are ready to drive the scanner with Co-Star KCAPTURE.

A WORD ABOUT VRS

VirtualReScan (VRS) is a technology invented by Kofax Image Products. Software VRS (SVRS) provides the advantages of virtual rescan by capturing the image, and then automatically cropping to page size, and adjusting brightness, contrast and gamma values to produce consistently high-quality images.  VRS may automatically switch to “interactive” mode when it encounters a ‘problem’ document. Interactive mode allows you to change VRS settings and preview their effect on the offending image WITHOUT RESCANNING.

Scanner Specifications

Criteria Unit of Measure Comment
Speed Rating pages/minute @ 200 dpi Pages per minute is a standard measure of the peak scanner speed.
Duty Cycle pages per day Duty Cycle is a measure of the scanner average daily throughput. Mid-range scanners (25-40 ppm) can be operated several hours per day but some manufactures limit the warrantee daily throughput. Therefore the duty cycle should be evaluated carefully for scanner selection.
Scanning Mode Simplex/duplex Simplex scanners scan one side (front) and duplex scanners scan front and back in one pass. Most office and production scanners offer simplex/ duplex scanning
Color/Grayscale and Monochrome  (B/W) na Black & White (Monochrome) scanning is used for most high-speed document scanning applications.  Grayscale and color scanning are used in selected specialized applications to enhance text/graphics documents.
Paper Size Business Card to 11″x17″ Production scanners typically provide continuous feed (Automatic Document Feeders; ADF) for business card to legal size documents. Selected scanners provide up to 11″x17″ size.
Paper Weight Tolerance From 12 to 34 pound weight (2.5-6 mils Paper weight and thickness tolerances are important measures of the scanners ability to feed continuously (ADF)
Document Feeding Mode Automatic Document Feeder (ADF) ADF is standard on most office scanners. Flatbed is offered as an option.
Service Options Return to Depot, Swap, On-site Depot service, Hot-Swap and on-site service options are attractive in most environments.
