Dell 1600n Multifunction Mono Laser Printer - Manual (Page 159)

Condition Suggested solutions
The scanner does not work. Make sure that you place the document to be
scanned face down from the scanner 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 cable is connected properly.
Make sure that the USB cable is not defective.
Switch the cable with a known good cable. If
necessary, replace the cable.
Check that the scanner is configured correctly.
Check the application you want to use to make
certain that the scanner job is being sent to the
correct port.
The unit scans very slowly. Check if the multi-function printer is printing
received data. Scan the document after the current
job is completed.
Graphics are scanned more slowly than text.
Communication speed becomes slow in scan mode
because of the large amount of memory required to
analyze and reproduce the scanned image.
