Basic troubleshooting tips
Simple issues such as smudges on the scanning glass or loose cables can cause your product to
produce fuzzy scans, operate in an unexpected manner, or fail to operate. Always check the following
items when you encounter scanning problems.
●
If scans are fuzzy, check to see if the scanning strip to the left of the scanning glass is dirty or
smudged. If so, clean the scanning strip.
If you are scanning a document that will be analyzed using Optical Character Recognition (OCR),
make sure that the original document is clear enough to be analyzed.
●
Make sure that the Ethernet and power cables are firmly seated in their respective connectors on
the back of the product, and that the power cord is plugged into a working electrical outlet or
surge protector.
●
Ensure that the product is receiving power.
◦
Check that the green LED on the power supply case is on.
◦
If the green LED is not on, ensure that power is available to the power outlet or surge
protector that the power supply is plugged into.
◦
If power is available to the power outlet or surge protector but the green LED is still not on,
the power supply might be defective. Contact
for assistance.
●
Make sure that the two formatter status LEDs on the back panel drawer assembly are green (one
should glow steadily, the other should blink). This indicates that the formatter is functioning
correctly.
●
Make sure that the product buttons are enabled.
●
Press the Power button to turn off the product, wait 30 seconds, and then press the Power button
again to turn on the product.
●
Make sure the automatic document feeder (ADF) hatch is closed.
●
Verify that the product is connected to the LAN, and that the product is correctly configured to use
the network.
If you continue to have problems, it is possible that your firmware or associated drivers are out of date
or have become corrupted
to locate firmware and driver updates for your
product.
