Using the Microtek ScanMaker IISP Scanner

Scanning

 To Scan a document, take the following steps:

1. Turn on the scanner and wait for it to warm up (i.e., wait until lights stop blinking).

2. From the Program Manager, start Photoshop SLE from the Scanner group.

 3. Place document face down on glass.

Orientation should be such that the top left of your document is placed into the bottom left of the scanner (into the large red arrow in the corner).

4. Scanning the document

a. Specifying scan settings.

In Photoshop SLE, go to the File menu, and select Acquire followed by TWAIN...

This will bring up a dialog box for scanning. You will probably want to use different settings for different purposes. Here are a few suggestions for settings:

Purpose: OCR Black&White Grayscale Color

Scan Mode Line Art Line Art Grayscale Color

or Grayscale

Resolution 300 dpi 72 dpi 72 dpi 72 dpi

Scaling 100% 100% 100% 100%

If you are scanning something to display on the screen (and not for printing), use 72 dpi for the screen resolution. If you are having problems applying OCR to a document, you might try even higher resolutions. These are just suggestions. Feel free to adjust the settings to see what works best for what you are trying to do.

b. Preview the document.

Click on the Prescan button to preview the document.

c. Select the area to scan.

Use the cross hairs tool to select the area of the document you wish to scan (i.e., you do not have to scan the whole document). If you are scanning for OCR purposes, you do not need to create separate scans for separate columns.

d. Scan the document.

Click on the Scan button to do the actual scanning.

5. Refining the scanned image.

Play around with the Photoshop tools, if you want. :-) (You shouldn't need to make any adjustments if you are scanning for OCR.)

6. Saving your scanned image.

For OCR: save as: tif file format (IBM tiff, no compression), in the c:\scans directory.

OCR

1. From Program Manager, start the PageKeeper Portfolio application from the Scanner group.

(click OK, when it prompts you with a dialog box)

2. File menu, select Import from File...

Use the file dialog box to select the tiff file(s) you created when you scanned your document(s).

When you have selected all the files you wish to import, click the Import button -- this will open a new dialog box.

The main setting you may need to change here, is the Language. Use the Language button to specify the language(s) of the document (e.g., Spanish, English, etc.). Click OK to import your file(s).

If you choose to verify text, any ambiguous text will be highlighted in color. You can change this text, and then select Save Changes from the File menu when you are done. To complete the import, select Finish Import from the File menu. (If you are not doing any verification, you will not have to specify anything during import.)

To view your file, click on the Folders in the main PageKeeper window. Your imported documents will appear in the Shoebox folder. You can double-click folder icons to expand and shrink them and double-click document icons to view them. I have no clue how the imported files get named. :-)

3. Please use the file manager to delete your scanned tiff files when you are through.

P.S. DON'T FORGET TO TURN THE SCANNER OFF WHEN YOU ARE DONE!
