I just bought a new lexmark copier, scanner, fax,

OCR stands for Optical Character Recogniton.

It's a program that can take images of scanned documents, (text), and recognize each character, then retype it as a text document that can be edited or reformated as you wish.

Chances are you tried the OCR function, and haven't installe the option for OCR.

It's one of several software programs that would have come with the Installation CD which would also have included, the Drivers for the printer and scanner, a copy utility, diagnostic utility and other stuff.

In the opening menu, perhaps an extras menu will have the option to install OCR.

Try the installation again to see if there is the option.

Other than that, you should be able to "Aquire" images through the scanner via an immage utility (File / Aquire / Scanner), or Microsoft Office program (Insert / Image / From scanner or camera).
Also there is a PhotoCopy function on the device that takes a Scan from the scanner and prints it directly to the printer.

This should give you a good explanation of what ocr is.
