Hi Chazellepe.

So that we can better assist you, how is the printer connected?  Is it connected directly to the computer with a USB cable, or with a LAN cable to a router?  If it is connected with a USB cable, how long is the cable, and are there any devices, such as a USB hub or extender, connected between the printer and the computer?  Finally, which version of Windows 7 are you running on your computer?  Is it the 32-bit or 64-bit version?

We look forward to your reply.  Should you need immediate assistance, please contact us at 1-800-OK-CANON (1-800-652-2666).

Thank you for your reply chazellpe.

To ensure that the issue is not with the scanning unit of the machine, please make a copy and verify if you experience the same issue with blank lines.

If you don't then it indicates that there may be a communication issue between the printer and the computer.  Please unplug the USB cable from the computer and the printer.  Plug the cable, firmly, back into the printer first, and then plug the USB cable into a different port on the computer.  Next, scan a document.   If the error persists, it is recommended that you change the USB cable. 

If the issue still appears, after changing the USB cable, please contact us at 1-800-OK-CANON for further assistance.
