If none of the above solve the problem, try unplugging the MultiPASS

Chapter 8
Possible cause
An error may have occurred
during sending.
There may be a problem
with the telephone line.
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
Automatic Document
Feeder (ADF).
The receiving fax machine
may not support ECM.
Solution
Print an activity report and
check for an error code. See
the MultiPASS Desktop
Manager User's Guide.
Make sure you have a dial
tone on the handset. If not,
contact your local
telephone company.
Make sure the receiving fax
machine is compatible with
the MultiPASS C50 (which
is a G3 fax machine).
Check the MultiPASS C50
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
Automatic Document
Feeder (ADF). See page 6-6.
If the receiving fax does
not support ECM, then the
MultiPASS C50 sends the
fax in normal mode
without error checking.
