Do not use a SCSI ID for more than one SCSI device. Turn off the PC and all the devices in the SCSI chain down before changing SCSI IDs, connecting, or disconnecting SCSI cables. Hardware damage may occur if this precaution is not followed. Setting the SCSI ID 1. Turn off the PC and all connected SCSI devices. 2. Determine which SCSI IDs are not being used. 3. Using a pointed object, set the switches to an unused SCSI ID. · The Dimâge Scan Dual's SCSI ID is factory preset to 5. If 5 is not occupied, there is no need to change the SCSI ID. · Two operating SCSI devices in the same SCSI chain cannot share a SCSI ID. SCSI ID Dip Switch Settings 6 CONNECTING THE HARDWARE Connecting the SCSI Cable The SCSI cable SC-11 (DB25-to-SCSI-1) has been packaged with the Dimâge Scan Dual.

The current colour, brightness, and contrast changes are automatically applied to the preview image 2. Click on the appropriate window or move the sliders to increase or decrease the contrast and/or brightness. · The changes are automatically applied to the preview image. · Additional contrast and brightness simulations will be mapped around the center image. Correcting th e brightness an d contrast may eliminate the need for colour correc tions. Adjusting the Colour The colour picker consists of a colour map and a pointer. Adjust the colour of your image +/­ 20 points in any direction by clicking on any colour tone within the colour map. Colour corrections at the edge of the colour map are more saturated (stronger). Colour corrections closer to the center are less saturated. Colour corrections are automatically applied to all of the image simulations. 3. Place the colour correction you want to apply to your image within the the cursor, then click the mouse button. · The pointer will move to the new position on the colour map. · The RGB correction values are displayed to the right of the colour picker.

Click on . · The cursor will change to an hourglass and a progress bar will appear. · To cancel the scan, click on or press the escape key until the Cancelling Operation message box appears. Do not remove the film holder until the scan is finished. Interfering with the scanner during scan could result in image distortion. 2. Click on to exit the Dimâge Scan Dual driver software. The image will be opened in your photo application software. · The driver window will automatically close after each scan if "Close driver after scanning" was selected in the preferences dialog box. 3. Save the image using the instructions from your photo application software. Multiple imag es can be scanned befo re closing the software if Pho toshop is the host softw are.

Click on the corners of the cropping frame to resize the scan area proportionally. Click on the sides of the cropping frame to resize the scan area non-proportionally. Dimâge Scan Dual 39 SETTING THE RESOLUTION Image resolution is the number of pixels per inch (ppi or dpi) that represent your scanned image. Image size and resolution determine the size of your image file. Lower input resolutions result in shorter scan times. Higher input resolutions make larger output sizes and higher output resolutions possible. The rule to follow when scanning is, "bigger is better". We recommend you set the output resolution to the highest value your output device (printer, monitor, etc.) can handle. The input resolution will vary with the size of the scan area, magnification, and output size. 1. Select the desired output resolution from the output resolution drop-down list. · Values can also be entered directly to the output resolution list box. · This menu is dimmed and cannot be accessed when the units menu is set to pixels. 2. The dimensions of the cropping frame are displayed in the input size text boxes. · Values can also be entered directly to the input size list boxes. · The values will change if a different unit of measure is selected. 3. Enter the desired output size (maximum 3 digits). · The output size is limited by the maximum resolution of the scanner. · The values will change if a different unit of measure is selected. · The output size windows are dimmed when the units menu is set to pixels. 4. The input resolution list box displays the lowest input (scan) resolution necessary to achieve the desired output size and resolution. · Input scan resolutions can also be selected from the drop-down list or entered directly into the input resolution list boxes. · Click on to lock the inpu t size settings. The icon will change to . Click again to unlock. · The magnific ation window displays the ou tput/input size ratio as a perc entage. 40 RESOLUTION NOTES Resolution and Output Size Output resolution is determined by hardware. The Dimâge Scan Dual driver software automatically determines the correct scan resolution to obtain the desired output size and resolution. To determine the final dimensions of a displayed or printed image yourself, multiply the dimensions of the scan area by the scan resolution (input resolution), then divide by the resolution of the output device (output resolution). Resampling Up Resampling up occurs when pixel values are interpolated to create an output resolution higher than the input resolution value. Resampling up generally results lower image quality. Users of the Dimâge Scan Dual need to be aware of resampling because image corrections entered in the driver software are applied after the image has been scanned and sent to the CPU. Resampling up will occur when the scanner's output resolution is set higher than the input resolution at magnification greater than 100.
