My Dell 964 printer is on the list that says it's not compatible with Windows 7. I use the Compatibility mode, I used Vista SP2 and my printer installed on Windows 7. We had some issues recently with a Belking N not communication with a 3300 adapter, may or may not be related if you have a Belkin N router.
Please follow the instructions below and then tell me what happens.
First, let's make sure your computer has the latest Windows Updates, especially .net framework, needed to run many applications and the latest Java.
I recommend that you use these Recommended Wireless Router Settings to get the best communications between the printer and all the computers.(This printer can be used wirelessly if the printer has the wireless card)
Disconnect your printer.
Download and run this patch to completely remove the printer from your computer. Run the patch(a MUST on Vista machines) untiul it prompts you to restart yopur computer. The patch mau or may not work for Windows 7 If not, then Manual Printer Driver Removal
Restart your computer.
Download the proper drivers.
Right click on the setup.exe file, left click properties, left click compatibility. Change the compatibility to Vista. Then install the proper drivers. You'll be prompted when to connect the printer(powered on)
***To install drivers, sometimes the file unzips and does nothing. You have to look for the setup.exe file, right click on it, then left click run as administrator***
Choose your printer. Beneath your printer, select your operating system. You'll be redirected to another page. Then click on show all steps. It will walk you through the installation process.
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.
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.
