If a black stripe appears on the back-side of scanned images or if dirt appears on the paper documents upon scanning or for preventative measures, we recommend that you clean your scanner as needed with a cleaning card.

It is best to perform a cleaning at the beginning or end of the day. A cleaning card does not clean the ink jet nozzles, so please remove the ink cartridge and perform a nozzle cleaning.

1. Turn OFF the scanner.
   
   
   
2. Disconnect the scanner and computer.
   
   
   
3. Turn ON the scanner while pressing the START button and the STOP button.
   
   
   
   If the scanner turned ON properly, the power LED continues to flash.
   
   
   
4. Pull the Eject Stopper.
   
   
   
5. Place the cleaning card in the document tray.
   
   
   
   
6. Press the START button to start cleaning.
   
   
   
7. Please repeat steps 5 and 6.
   A typical cleaning is feeding the card 3 to 7 times. If the scanner is extremely dirty, you may need to use another cleaning card.
   
   
   
8. Turn OFF the scanner.
   
   
   
9. Connect the scanner and the computer.
   
   
   • You cannot scan the document without the computer.
   • Allow 1 to 2 minutes for the moisture on the Canon CR-Series scanner from the cleaning card to thoroughly dry before scanning documents.
