Check the Error Correction Mode setting
Usually, the printer monitors the signals on the telephone line while it is sending or receiving a fax. If the
printer detects an error during the transmission and the Error Correction Mode setting is On, the printer
can request that the portion of the fax be resent. The factory-set default for error correction is On.
You should turn off error correction only if you are having trouble sending or receiving a fax, and you
are willing to accept the errors in the transmission. Turning off the setting might be useful when you
are trying to send a fax overseas or receive one from overseas, or if you are using a satellite telephone
connection.
1. From the Home screen on the printer control panel, touch the Menu icon, and then touch Settings.
2. Touch Fax Settings, and then touch Fax Send.
3. Touch the button next to Error Correction Mode to turn the setting off or on.
Send to a different fax machine
Try sending the fax to a different fax machine. If the fax quality is better, the problem is related to the
initial recipient's fax machine settings or supplies status.
Check the sender's fax machine
Ask the sender to try sending from a different fax machine. If the fax quality is better, the problem is with
the sender's fax machine. If a different fax machine is unavailable, ask the sender to consider making
the following changes:
● Make sure the original document is on white (not colored) paper.
● Increase the fax resolution, quality level, or contrast settings.
● If possible, send the fax from a computer software program.

Introduction
Certain types of problems can indicate there is a network communication problem. These problems
include the following issues:
Poor physical connection
Check the cable connections.
1. Verify that the printer is attached to the correct network port using a cable of the correct length.
2. Verify that cable connections are secure.
3. Look at the network port connection on the back of the printer, and verify that the amber activity
light flashes indicating network traffic, and the green link-status light is continuously lit indicating a
network link.
4. If the problem continues, try a different cable or port on the hub.
