To scan documents for editing and saving as PDF file, you will need to install the Lexmark OCR scan software on your computer. The Lexmark scan software (no downloadable version) is only available on the installation disc that came with your printer. If you lost the disc, please contact Lexmark Technical Support Center for assistance.

Please visit the Lexmark website to download and install the Lexmark Prevail Pro705 Printer Driver on your computer.

Simply follow the instructions on your computer screen to complete the installation.

Reinstall printer to fix problems

If you are scanning documents to edit or save as PDF file, you will need to install the OCR scan software on your computer. The Lexmark OCR scan software is available only on the installation disc that came with your printer. If you lost the disc, please contact Lexmark Technical Support Center to request for one.
If scanning from your printer to your computer was working previously, then it could be just a slight communication problem. A quick fix for most communication errors can be achieved by resetting the printer and/or rebooting the PC. Simply disconnect the printer from your computer (if USB connected) > reboot your pc > unplug and re-plug the printer into the power source to reset it. When the printer turns on, reconnect it to your computer. Then try to scan again once the computer fully recognizes the USB connection (if USB connected). If printer is connected wireless, wait until the WiFi light on the printer turns on solid green before trying to scan a document.

You will need to update the printer software installed on your computer to install the OCR scan software. The Lexmark OCR scan software is available only on the installation disc that came with your printer. Just re-insert the install disc into the computer hard drive and run the installation setup.
If you lost the disc, please contact Lexmark Technical Support Center for assistance.
