You need to use the Scan to SMB function.
First create a folder, share it over your network.

Go to the MFP and under the scan to SMB enter the IP and path to the folder, enter the ID and password for the computer.

This will scan to the shared folder.

• in the device manager check the USB chipset if it is VIA, or ALI, or SIS then it is the usb 1.0 compatibility issue , it ll work some time and sometimes it ll not ....
• the usb cable shuld not be more than 6 feet in length

Thanks for the tip...the problem is NOT a black line but a wide yellow line on the right side of the paper. It starts out about a quarter of the page in width and diminishes in size to about a half inch in width after many repeated scans.

The glass IS clean , and even when the glass had some smudges here and there, I never had a yellow stripe problem!

Scanner bulb is bright and even the entire length of bulb (no dark areas) so I don't think it is the bulb!
