10-20 Troubleshooting
Cause
The one-touch or coded
speed dialing number you
used may not be registered
for the feature you want
to use.
The other party's fax may be
out of paper.
There may be other documents
being sent from memory.
The telephone line may not
be working properly.
The receiving fax machine may
not be a G3 fax machine.
The receiving fax machine may
not be working properly.
The document may not be
properly inserted in the
ADF.
The other party's fax may
not support ECM.
The phone line may be in
poor condition, or you may
have a poor connection.
The sending fax machine may
not be functioning properly.
Solution
Check the one-touch or coded
speed dialing button and be
sure it is registered correctly.
Call the other party and ask
them to make sure paper is
installed.
Allow time for the current
document to finish sending.
Make sure there is a dial tone
when you lift the telephone.
If not, contact the local
telephone company.
Make sure the receiving fax
machine is compatible with
the MultiPASS (which is a G3
fax machine).
Check the MultiPASS by
making a copy. If the copy is
clear, the problem may be in
the receiving fax machine.
Remove the document and
feed it correctly into the
ADF. See page 1-13.
Some fax units do not
support ECM transmission.
If the other party's fax does
not support ECM trans-
mission, then the document is
sent in the normal mode
without error checking.
Lower the transmission speed.
See the Advanced: Send Fax
dialog box (page 8-5) and the
Advanced: Receive Fax dialog
box (page 8-9).
The sending fax machine
usually determines the fax's
quality. Call the sender and
have them make sure the top
cover and scanning glass on
their fax machine are clean.
