Installation and configuration

Installation and Configuration

  • An installation CD that includes drivers, manuals, and diagnostic software will be included with the scanner.

    • The same tools may also be available as downloads from the manufacturer's website.


Power and connect a scanner

Power and Connect a Scanner

  • Scanners can connect to a computer using a USB, FireWire, network, or parallel port. Some scanners may connect using a SCSI interface.

  • Some scanners can draw all the power they need from the USB or FireWire connector.

    • All-in-ones connect directly to AC power.

    • Scanners that do not include a printer can connect using an AC power adapter.

  • After unpacking the scanner, connect the appropriate power and data cables.

    CAUTION:Some scanners are packed for shipping with the scanner assembly taped or blocked off to prevent damage in transport.


Install and update device driver

Install and Update Device Driver

  • Once the scanner is connected and started, the computer operating system may be able to discover the scanner through the Plug and Play (PnP) process.

  • Install the driver software from the manufacturer.

    • The manufacturer's website may provide more up-to-date software.


Configuration options and defaults1

Configuration Options and Defaults

  • A scanner may come with applications such as:
