First thing you need to try is remove all disks from the computer, CD's, DVD's, Media Cards, External Harddrives, Floppy disks or USB drives.

Any of these could be attempting to boot and causing the error. If you remove all of these and still get the same error, either the hard drive in your laptop or the installation of windows is damaged.

If the installation is damaged, you can restore the system using the factory set of Recovery disks from Toshiba but this will wipe out any files and programs you have saved on the computer.

If you try this and it fails, the hard drive is likely faulty and will need to be replaced, then the Recovery set can be used to set up the computer using the new hard drive.

Either way if you do have important files on the drive and need them back you may need to send the drive to a pro for Data Recovery. If so comment back here and I will get you contact info for one of the companies I use.

Not sending scan picture to computer

This sounds like a communication error. If you go to "Printers & Faxes" or whatever your opperating system calls it (in Control Panel) is the printer greyed out and showing as 'Offline'?

If so I have writtren a few guides for offline printer issues for Windows operating systems that can be found here:

Hope this helps.

You need restore disks or an opperating system to restore any computer to factory condition. Simply put the disk 1 in your dvd/cd drive and go from there. It usually takes 45-60 minutes to do this.

IF you don't have restore disks you can make them on your system (if its running) or you can call the manufacturer and they will send you them for a small fee.
