Check all line cord connections. Make sure the telephone line cord is plugged into the
telephone wall jack and the LINE jack of the machine. Make sure your machine has a dial
tone by pressing the Hook button in Fax mode. If you subscribe to DSL, VoIP, or
MagicJack services, call your service provider for connection instructions.
Make sure you pressed Fax and the machine is in Fax mode.
Print the Transmission Verification Report and check for an error.
Contact your administrator to check your Secure Function Lock Settings.
Ask the other party to check that the receiving machine has paper.
Try changing your resolution to Fine or S.Fine. Make a copy to check your machine's
scanner operation. If the copy quality is poor, clean the scanner.
There is probably temporary noise or static on the line. Try sending the fax again. If you
are sending a PC-Fax message and get RESULT:NG on the Transmission Verification
Report, your machine may be out of memory. To free up extra memory, you can turn off
Fax Storage, print fax messages in memory or cancel a delayed fax. If the problem
continues, ask the telephone company to check your telephone line.
If you often get transmission errors due to possible interference on the telephone line or if
you are using a VoIP system, try changing the Compatibility setting to Basic(for VoIP).
Make sure you are loading the document correctly. When using the ADF, the document
should be face up. When using the scanner glass, the document should be face down.
Black vertical lines on faxes you send are typically caused by dirt or correction fluid on the
glass strip. Clean the glass strip.
Suggestions
This is usually caused by a poor telephone connection. Make a copy; if your
copy looks good, you probably had a bad connection, with static or
interference on the telephone line. Ask the other party to send the fax again.
The corona wire for printing may be dirty.
Clean the corona wire in the drum unit.
The sender's scanner may be dirty. Ask the sender to make a copy to see if
the problem is with the sending machine. Try receiving from another fax
machine.
Left and right margins are cut off or a single page is printed on two pages.
Turn on Auto Reduction.
