How do I use my x5495 to scan a resume and then to edit it with my Dell XP computer?

Greets - This is taken right from the device manual:
Scanning text for editing
Use the Optical Character Recognition (OCR) software feature to turn scanned images into text you can edit with a word-processing application.
1 Make sure: • The printer is connected to a computer, and both the printer and the computer are on. and that the ABBYY Fine Reader is installed.
2 Load an original document facedown on the scanner glass.
3 From the desktop, double-click the Productivity Studio icon.
4 Click Scan.
5 Select the Document option.
6 Click Start.
The scanned document is loaded into your default word processing application. You can now edit the document.
Happy editing, Mikeywaf

You'll need to scan the document with an OCR software package (Optical character recognition) that will recognize the letters themselves and transmit them to word processing application, such as Word for Windows. Most scanner packages come with some form of OCR utility, so check your installed software. You may already be set up!
Best of luck, William
