Scanning problems
• Make sure that you place the original to be
scanned face down on the scanner glass, or
face up in the 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 machine cable is connected
properly.
• Make sure that the machine 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 or the application you want to use
to make certain that the scanner job is being
sent to the correct port (for example,
USB001).
• 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.
• 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. Try your job again when that job is
finished.
• The selected port is currently being used.
Restart your computer and try again.
• The machine 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 machine 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.
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 machine 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.
• Check for copy paper or pieces of copy paper
remaining in the machine 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 scanner lid may be left open while copies
are being made.
• Turn the machine off and back on.
