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. 75 g/m
2
(20 lb bond) paper is
recommended.
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 machine may be turned on and off
frequently.
The scanner lid may be left open while
copies are being made.
Scanning problems
Condition Suggested solutions
The scanner does
not work.
Make sure that you place the original to be
scanned face down on the scanner glass, or
face up in the DADF.
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 printer cable is connected
properly.
Make sure that the printer 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.
In case of use of account feature, make sure
that you have extra scan count remained. For
example, if you try to scan 10-page document
while you have 5 scan count left, the scan job
would be canceled.
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.
