Errors occur frequently while sending or receiving.
The telephone lines may be in poor condition, or you may have a poor
connection.
Lower the transmission or reception speed. (If you are using the Fax Setup
Utility, see the MultiPASS Desktop Manager Software Guide. If you are using
the operation panel, see the Standalone Fax Manual.)
The sending fax machine may not be functioning properly.
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.
Cannot receive a fax automatically.
The MultiPASS may not be set to receive automatically.
For the MultiPASS to receive faxes automatically, the receive mode must be set
to FAX ONLY MODE, Fax/Tel Mode, or ANS.MACHINE MODE. If you have
set ANS.MACHINE MODE, confirm that an answering machine is connected
to the MultiPASS and that it is turned on with an outgoing message properly
recorded.
The MultiPASS may have a document stored in memory.
Print out any faxes stored in memory (see page 4-20).
An error may have occurred during reception.
Check the LCD display for an error message (see page 7-6).
The multi-purpose tray may be empty.
Make sure paper is loaded in the multi-purpose tray (see page 2-11).
The telephone line may not be connected properly.
Make sure all line connections are secure (see your Quick Start Guide).
