Samsung SCX-4520S, SCX-4720FS manual Scanning Problems

Scanning Problems

Condition	Suggested solutions
The scanner does not work.	• Make sure that you place the document to be
	scanned face down on the document glass, or
	face up in the Automatic Document Feeder.
	• There may not be enough available memory to
	hold the document you want to scan. Try the
	Prescan function to see if that works. Try
	lowering the scan resolution rate.
	• Check that the USB or parallel cable is
	connected properly.
	• Make sure that the USB or parallel cable is not
	defective. Switch the cable with a known good
	cable. If necessary, replace the cable.
	• If you are using a parallel cable, ensure that it is
	compliant with IEEE 1284 standards.
	• Check that the scanner is configured correctly.
	Check scan setting in the SmarThru
	Configuration or the application you want to use
	to make certain that the scanner job is being
	sent to the correct port, for example, LPT1.
The unit scans very slowly.	• Check if the machine is printing received data.
	If so, scan the document after the received data
	has been printed.
	• Graphics are scanned more slowly than text.
	• Communication speed slows in scan mode
	because of the large amount of memory
	required to analyze and reproduce the scanned
	image. Set your computer to the ECP printer
	mode through BIOS setting. It will help to
	increase the speed. For details about how to set
	BIOS, refer to your computer User’s Guide.
