Canon CR-55 Images Are Not Scanned, Documents Do Not Feed Properly

Check the following if the scanner does not scan an image when you perform the scanning operation:

•Is the scanner correctly connected to the PC?

•Has the scanner driver been installed?

•Has the application software been installed correctly? Has the application software been set up correctly?

•Is there a problem in the PC system?

Note

•If a system error causes the scanner to stop functioning, turn OFF the scanner and wait at least ten seconds before turning it back ON.

•Make sure that the last document scanned was scanned correctly when scanning resumes.

The following are possible causes of a document failing to feed properly. Check each possible cause.

Cause	Attempting to scan a document of a size, thickness, or
	weight that the scanner cannot scan.
Remedy	Check the size, thickness, and weight of the document. (For more
	information on precautions concerning documents, see
	“Documents,” on p. 37.)

Cause	The rollers inside the scanner are dirty or worn.
Remedy	Clean the rollers. (For instructions on cleaning the rollers, see
	“Cleaning the Sensor Glass and the Rollers,” on p. 46.) If the
	rollers are worn, then they should be replaced. Contact your local
	authorized Canon dealer or service representative to purchase a
	roller replacement kit.
