Scanning problems

Dell Scan Manager problems

Blank copies print 
out

Ensure that the original is face down on the 
scanner glass or face up in the ADF.

Image rubs off the 
copy easily

Replace the paper in the tray with paper 
from a new package.

In high humidity areas, do not leave paper 
in the printer for extended periods of time.

Frequent copy paper 
jams occur

Fan the stack of paper, then turn it over in 
the tray. Replace the paper in the tray with 
a fresh supply. Check/adjust the paper 
guides, if necessary.

Ensure that the paper is the proper paper 
weight. 75 g/m

2

 (20 lb bond) paper is 

recommended.

Check for copy paper or pieces of copy 
paper remaining in the printer after a paper 
jam has been cleared.

Toner cartridge 
produces fewer 
copies than expected 
before running out of 
toner

Your originals may contain pictures, solids, 
or heavy lines. For example, your originals 
may be forms, newsletters, books, or other 
documents that use more toner. 

The printer may be turned on and off 
frequently. 

The scanner lid may be left open while 
copies are being made.

SUGGESTED SOLUTIONS

CONDITION

SUGGESTED SOLUTIONS

The scanner does 
not work

Ensure that you place the original to be 
scanned face down on the scanner glass, or 
face up in the ADF.

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.

Ensure 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 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.

The unit scans very 
slowly

Check if the printer 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.

Message appears on 
your computer 
screen:

“Device can't be 
set to the H/W 
mode you want.”

“Port is being used 
by another 
program.”

“Port is Disabled.

“Scanner is busy 
receiving or 
printing data. 
When the current 
job is completed, 
try again.”

“Invalid handle.”

“Scanning has 
failed.”

There may be a copying or printing job in 
progress. When that job is complete, try your 
job again.

The Selected port is currently being used. 
Restart your computer and try again.

The printer cable may be improperly 
connected or the power may be off.

The scanner driver is not installed or the 
operating environment is not set up properly.

Ensure that the printer is properly connected 
and the power is on, Then restart your 
computer.

The USB cable may be improperly 
connected or the power may be off.

SUGGESTED SOLUTIONS
