Scanning in the IRCs Using the Epson 4490

Need to know how to scan using the Fujitsu ScanSnap? Instructions here.

All scanners are kept in IRC 3, the talking IRC, due to the noise they produce while operating.

Scanning an Image

  1. Make sure the scanner is connected to your computer and to the power source.
  2. Go to Machintosh HD>Applications> and launch EPSON Scan.app .
  3. If an EPSON Scan cannot be started error appears, quit the program. Unplug the USB cord from the back of the computer and plug it in again. Also make sure the scanner is plugged into power. Reopen EPSON Scan and try scanning again.

  4. On the top right of the EPSON Scan window, click on the drop-down menu under Mode and select Home Mode.
  5. Open the scanner and place the image/text to scan face down on the bed of the scanner.
  6. Click on the drop-down menu under Document Type in the EPSON Scan window and select an appropriate document type.
  7. Under Image Type choose the correct color type.
  8. Under Destination choose Screen/Web for low-quality images or Printer for high-quality images and text.
  9. Click on Preview.
  10. In the preview window, click and drag to mark out the section you want to scan with the crosshair pointer.
  11. Click on Scan.
  12. In the File save settings dialog, choose the location to save the picture i.e. the Pictures, Documents or Desktop window.
  13. Under Image format, choose a suitable format according to the quick guide below.
    • JPG is typically suited for snapshots or web images, as it produces small, highly compressed images with some loss of image quality. In the Options button, you can trade size for quality. Higher quality images take up more space.
    • TIFF saves your image no loss of image data. TIFF files are usually large and thus unsuitable for email or webpages. This format is commonly used by people who plan to edit their images or otherwise need very high-quality.
    • PDF is the standard format for scanned text.
  14. Click on OK.

Find your files in the location you saved them. Consider editing your images in Photoshop. For PDF or Multi TIFF files, you can add another page to the same document by clicking on Add page on the dialog box following or save the document as it is by selecting Save File or scan another page in place of the previous scan by clicking on Edit page.

Changing the Image Resolution

  1. Go to Machintosh HD>Applications and launch EPSON Scan.app
  2. On the top right of the EPSON Scan window, click on the drop-down menu under Mode and select Home Mode.
  3. Under Destination select one of Screen/Web, Print or choose Other and enter a DPI (Dots Per Inch) value based on the quick guide below:
    • A lower DPI makes for a faster scan.
    • A higher DPI will create a clearer scan, but will take longer.
    • If you are scanning an image for a web page or a computer screen 72 DPI will suffice (that is the resolution of a standard computer screen).
    • If you wish to enlarge the image from the size you are scanning, increase the DPI.
    • Below 300 DPI is sufficient for most scans of photographs or printed material.

Scanning Film or Slides

  1. If you want to scan film or slides, ask for a film holder at the CUS Helpdesk. They will also install it for you.
  2. Go to Machintosh HD>Applications and launch EPSON Scan.app
  3. On the top right of the EPSON Scan window, click on the drop-down menu under Mode and select Professional Mode.
  4. Click on the drop-down menu under Document Type in the EPSON Scan window and change it to the type of film you are scanning. Before you scan, make sure the resolution is at least 300 DPI - you may have to increase the resolution to anywhere up to 3200 DPI (see Changing image resolution) for instructions on how to do this.
