Image of received fax is very poor. Contact the person sending 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 machine
to ensure that it is working properly. Then ask them to send the fax again.
If there is still a problem, try making a copy of a document on the local
machine to make sure it is working properly.
Dialling was tried with a Speed Dial number but nothing happened.
Make sure that the Speed Dial number being used is programmed
correctly. When dialling a two or three digit number, be sure to press
Speed Dial before entering the number. Check to see if the Auto Start
feature is turned off. If in the OFF state, Start must be pressed before dial-
ling will commence.
Local machine will not answer the telephone or receive faxes. First
check to see that the power cord is connected properly. Also check the
reception mode setting of the machine. This machine will not receive
faxes automatically in the manual answering mode [TEL] (see Machine
Settings).
Documents received are light or have vertical streaks on them, and
machine is not out of toner. Gently wipe the lens surface of the
machine's LED array, and then check to see if the machine is working
properly (see Toner Cartridge Replacement). If the machine still does not
work properly, remove the image drum (see Image Drum Unit Replace-
ment), tap the toner cartridge, and slowly swing it 20 to 30 degrees verti-
cally several times. Be careful not to let the toner leak from the cartridge.
If this does not work, the image drum unit may need to be replaced.
Contact your supplier to get a replacement.
Machine is set for delayed transmission but it did not send. Check the
display to make sure that the machine's clock is set to the correct time (see
Clock Adjustment).
Machine will not poll a remote machine. Call the person at the remote
machine and make sure that they have loaded documents and that their
machine is set to polling transmission mode.
Machine is connected to a PBX but it is not possible to dial out. Be
certain that the dial prefix is entered before the telephone number for each
number dialled or programmed into the machine. Additionally, the
machine must be programmed for PBX operation before it will work with
a PBX (see Connecting to a PBX).
