You sent a fax but it was received completely blank. Make sure that
you have loaded your document face down.
The image received on your MFP machine was very poor. Contact the
person sending you the fax and ask them to change their Transmit
Resolution and Type of Original settings. Ask the person to make a copy
of the document on their fax machine to ensure that it is working properly.
Then ask them to send the fax again. If you still have a problem, try
making a copy of a document on your machine to make sure it is working
properly.
You tried dialing with a One-Touch key or an Auto Dial code but
nothing happened. Make sure that something is programmed into the
One-Touch key or Auto Dial code you are using. Check the fax number to
make sure it was entered correctly (see the Dial Directories chapter).
When you are dialing with an Auto Dial code, be sure to press the AUTO
DIAL key before you enter the code. If your MFP machine has the Auto
Start feature turned off, you will have to press the START key before
dialing will begin (see the section on Programming).
Your MFP machine does not answer the phone or receive faxes. First
check to see that the power cord is connected to the AC outlet. Also
check the reception mode you are using. Your MFP machine will not
automatically receive faxes in manual answering mode [TEL]. See
"Setting the Answering Mode" in the Installation section.
Your received documents are light or have vertical streaks on them
and you are not out of toner. Gently wipe the lens surface of your MFP
machine's LED array and then see if the machine works properly (refer to
"Replacing the Toner Cartridge"). If your MFP machine still does not work
properly, remove the image drum unit (refer to "Replacing the Image
Drum Unit"), tap the toner cartridge, and slowly swing it 20-30 degrees
vertically several times. Be careful not to let the toner leak from the
cartridge. If this does not work, you may need to replace your image drum
unit. Contact your dealer to get a replacement.
You set your MFP machine for delayed transmission but it did not
send. Check the display to make sure that you have set your MFP
machine's clock to the correct time. See "Setting the Clock" in the Instal-
lation section.
