There is a
problem either with the Line Interface Unit (LIU, also known as the
fax/phone line connector) or the fax hardware, because the unit is
having problems sending or receiving faxes. The unit may hang on
"Initializing." This document explains how to troubleshoot the LIU and
Please perform the following:
Front panel hangs on "Initializing"
Testing the LIU
Pull the power cord connector from the back of the base unit to recover from the error.
Unplug the LIU from the back of the
ADF. It is located on the left side (facing it), and is where you plug
in the telephone lines.
Plug the power cord back in, power it up, and see if it hangs without the LIU inserted.
If it does not hang without the LIU
inserted, power the unit down, plug the LIU back in, and power it back
up. If it hangs, the LIU is faulty.
If it does hang without the LIU attached, unplug the ADF from the base and see if it hangs. If it does, the base is faulty.
The primary test for the LIU is whether or
not you get a dial tone. Sometimes, you need to re-seat the phone line
several times to get a good connection. If after trying the things
below, there is still no dial tone, or initialization hangs, the LIU may
need to be replaced.
Verify that the phone line is connected directly from the wall jack to the plug in the LIU that says "To Wall Jack."
Verify that the LIU is plugged
securely into the product. If it is not, there will be a message at
power-up saying the LIU is not connected. If it is, the date and time
If the LIU was re-seated, cycle the power on the unit. The unit should display the date and time.
Unplug all other accessories, like a
telephone answering machine or modem. If the LIU appears to work fine
after unplugging them, these accessories may be interfering.
Place a document in the Automatic Document Feeder (ADF). The display will flash "Document Loaded."
Press Start Fax to verify there is a dial tone. If so, try sending a fax.
If there is not a dial tone, unplug
the product from the wall jack, and plug in a regular telephone to
verify there is a dial tone at the wall jack.
If there is no dial tone on the telephone, the wall jack or phone line may be faulty
