Although the Helpdesk does not provide support for student-owned scanners, there are several Epson scanners available around campus.



Scanners can be found in the following locations:


Scanning images, slides, and even photo negatives can be accomplished via Adobe Photoshop or Epson Scan.

Using Adobe Photoshop

  1. Open Adobe Photoshop.
  2. Click File > Import > "Scanner.''
  3. Select the image type, and then click scan.

The image will be automatically imported into Photoshop. Depending on the scanner, you may need to Preview the image before actually scanning.

Using Epson Scan

This option is available to Macs only.

1.  Check the scanner to see that it's green light is on (indicating it's on). Please note that the scanner is usually on, but if it is not, press the button on the front left. Additionally check for dirt and dust, wipe it clean.

2.  Place the top corner of your document in the top left of the scanner. Note whether it is portrait or landscape and make sure to change the setting to match later.

3.  Go to Applications > Epson Scan software and a small window should pop up. In said window select Professional Mode

4.  For increased detail, change the dpi (dots per inch) to a higher number- also keep in mind that 300 dpi is standard.

Set the resolution to 72 or 96 dpi for Powerpoint or the web. Set the resolution for 150 dpi for low resolution printing, 300-600 dpi for high resolution printing. If you are making archival scans, the resolution should be set at 600 dpi or higher.

Note: in terms of the scaling what you see in the screen is not always what you get when you print your images.

5.  Press Configuration in the bottom middle of the window. Go to the Other tab, and change Work Area from Macintosh HD to Scratch Disk. Press OK.

6.  Change any parameters you need to (Size, Orientation, B/W)

    1. Click on Descreening Filter at the bottom of the settings window
    2. Place item on the glass and click Preview.
    3. Crop the image by drawing a box around it.
    4. Set Target Size (expand window by clicking on lower right corner and dragging) to 3,000 pixels on the longest side of the image.

7.  Press Scan

8. Edit the Image Type/Name and File Location and press Scan again.

    1. Save the image, title as desired. Tiffs are recommended for archival purposes, images for the web should be jpgs. If you make tiffs, then jpgs or any other image format can be made as derivatives of any size. If you only make jpgs, your images will be ready for the web but will not make good derivatives in other formats and as changes are made to them, data will be lost.

9. Voila! You just scanned a page. If you want to scan more than one image in the same document, select PDF in the Scan window. After you scan a page, keep clicking Add Page in the “Scanning complete” window until you’ve scanned everything.

Scanning Special Media

Student Computing labs located in the CMC are equipped with scanners that are capable of scanning both slides and negatives. The Nikon Super Coolscan located in CMC 102 is designed specifically for scanning these types of media. Please refer to the Slide Scanning article for more information on using this device.

It is also possible to scan various media including slides, photos, and photo negatives using the standard Epson flatbed scanners available in the CMC. To scan these items special templates or attachments are needed from the SCIC. For specific directions on scanning media try one of the links below:


OCR, optical character recognition, is used to scan printed text such that it may then be edited on a computer. Adobe Acrobat Professional, which is installed on all lab computers, is capable of OCR. To recognize text in a scanned image, first create a PDF using either "PDF from Scanner". If you already have the image in an electronic format, "PDF from File" will work as well. Once the image is in PDF form, go to Document > OCR Text Recognition > Recognize Text using OCR.

The text created by Adobe Acrobat will be in PDF form, which can be annoying to edit. It may be faster to copy/paste text into Microsoft Word before working with it.
