Q Is the telephone line working properly?
A Make sure there is a dial tone when you press [Hook] or
when you lift the optional handset or the handset of any
external telephone connected to the machine. If there is
no dial tone, contact your local telephone company.
Q Is the recipient's machine a G3 fax machine?
A Make sure the recipient's machine is compatible with your
machine.
Q Did the recipient's machine answer within 35 seconds
(after all automatic redialing attempts)?
A Ask the recipient to check the machine. For an overseas
call, add pauses to the registered number. (See "Dialing an
Overseas Number (With Pauses), " on p. 3-20.)
Q Is the Processing/Data indicator lit?
A The external phone is busy. Please wait until the external
phone becomes free.
Q Is the machine overheated?
A Unplug the machine and let it cool for about 5 minutes.
Then plug in the machine and try sending again.
Memory fills up immediately when you try to send.
Q Are you sending with the resolution set to <SUPER
FINE>?
A If you want to keep your document quality, divide the
document into some parts and send them separately.
A If your document does not contain fine text or
photographs, set the resolution to <STANDARD>.
A If your document contains fine text or photographs, send
it directly rather than using a memory transmission.
Q Is a document stored in memory, leaving little memory
available?
A Print, send, or delete any documents stored in memory.
Faxes sent from the machine are spotted or dirty.
Q Is the recipient's machine working properly?
A Check the machine by making a copy. If the copy is clear,
the problem may be in the sender's machine. If the copy
is spotted or dirty, clean the scanner components. (See
"Scanning Area, " on p. 7-6.)
Q Is the document loaded correctly?
A Make sure the document is correctly loaded. (See "Loading
Documents, " on p. 2-4.)
