Problem Possible cause Solution
Images on faxes
received from the
MultiPASS C50 are
spotted or dirty
The receiving fax machine may
not be working properly.
Check the MultiPASS C50 by
making a copy. If the copy is clear,
the problem may be in the receiving
fax machine.
The document may not be
properly inserted in the
Automatic Document Feeder
(ADF).
Remove the document and feed it
correctly into the Automatic
Document Feeder (ADF). See page

The MultiPASS C50
cannot send a fax using
ECM (ECM TX does
not appear in the LCD
display when sending)
The receiving fax machine may
not support ECM.
If the receiving fax does not support
ECM, then the MultiPASS C50
sends the fax in normal mode
without error checking.
ECM receiving on the receiving
fax machine may not be turned
on.
If the receiving fax does support
ECM reception, call the other party
and have them check if ECM
reception is turned on.
Errors occur frequently
while sending faxes
The phone line may be in poor
condition, or you may have a
poor connection.
Lower the speed at which the unit
starts sending faxes in the Speed
option in the Send Fax tab. See the
MultiPASS Desktop Manager User’s
Guide.
