rds332000,

Make and model of your computer would be helpful. There are a few issues with a couple of model numbers.

First, let's make sure your computer has the latest Windows Updates, especially .net framework, needed to run many applications and the latest Java.

Disconnect your printer.

Download and run this patch to completely remove the printer from your computer. Run the patch(a MUST on Vista machines) until it prompts you to restart your computer.

Restart your computer.

Download the proper drivers.

XP Drivers

Vista 32-bit Drivers

 Vista 64-bit Drivers

All other drivers

Now install the proper Drivers. You'll be prompted when to connect the printer(powered on)

As for scanning, if you have the disk that came with the printer, then insert the Printer disk and stop it from running. Go to My Computer and double click on it. Look for the drive with the Dell disk in it. Right click on it, left click explore. Look for the OCR Folder. In the OCR Folder, there is an Abbyy Folder. right click on setup.exe, that's in the Abbyy Folder and left click run as administrator. This will install the OCR program.

Or

Try this FREE OCR Program.

Scanning

Scanning using USB connection, open the Dell All-In-One Center, click on scanning and copying and scan from there.

Scanning wirelessly, use the scan buttons on the printer.

What happens now?

rds332000,

Did you right click on the patch, left click run as administrator and run it until it prompted you to restart your computer?

Did you right click on the Vista 64-bit drivers and ;eft click run as administrator to install the printer drivers?

I still do not know if you have a laptop, desktop or what.

There are issues with the Dell Studio™ 1536 Is Unable to Print Documents

Rick

Is a Laptop.

Yes, a run the patch.

Sorry, I make a mistake, it's a desktop

rds332000,

Disconnect the printer, run the patch, install the proper drivers but when prompted, try a different USB Port. Please use a 5ft or smaller USB Cable.

Rick

If the back USB port(s) don't work, they try the front USB port(s)
