I have the Lexmark 3430. Print and copy works but it will not scan.

There is a firmware update for the Lexmark Pro900 Series printer that addresses print quality issues. Please visit the Lexmark website to download and install the Lexmark Pro900 Series Firmware Update.
After successfully updating your printer, try to print, scan or make a copy again to verify that the problem is fixed.
Should the problem continue, it might be a printhead problem. Please contact Lexmark Technical Support Center for further assistance.

okie first of all click on to start and then go to control pannel and then go to printer and faxes and then click on to add printer .then it would ask you to put the driver cd into the computer ,put the driver cd into the computer and then the computer would start installing the driver and after the driver is installed your printer will start working .if it doesnot work write me an email with your phone number and i will try to help you out on the same ,

The Vista drivers available on the Lexmark website do not contain the All-In-One Center. They are minimum drivers. Although the scan drivers are shipped with the web package, they cannot be used by the All-In-One Center since it is not included. Please use Windows Scanners and Cameras or Photo Gallery for Scanning.

Try this:

Uninstall printer and printer programs. Go to this site download and reinsall program/driver.

No it doesn't work in the X3430 printer, I tried using the #23 cartridge myself. Only after trying it did I read the side of the box, which doesn't list this printer.

i lost my disk for my Lexmark 3430, is there still a way i can load it?

what kind do you have, cancel the print job. turn printer off, check to ink, take it out and shake it put it back in. start printer, let it run thue it's thing. then try to print. The ink maybe out.

I believe you have to push the scan button in order for it to scan and save. The copy buttons will only print either a black copy or a color copy.
