memory.
An error may have occurred during
reception.
The Multi-Purpose Tray may be empty.

* FAX-JX500/JX300 only.
Allow time for those documents to finish sending.
Print an activity report and check for an error (see page 54).
Make sure there is a dial tone when you press [Hook] or when you lift the
Handset. If there is no dial tone, contact your local telephone company.
Make sure the receiving fax machine is compatible with this fax machine (which
is a G3 fax machine).
Check the fax by making a copy (see page 18). If the copy is clear, the problem
may be in the receiving fax machine. If the copy is spotted or dirty, clean the
scanner components (see page 63).
Remove the document, stack it if necessary, and load it into the Document Tray
correctly (see page 16).
If the receiving party's fax machine does not support ECM, then the document is
sent in normal mode without error checking.
Make sure ECM is on (see ECM TX on page 51).
Lower the transmission speed (see TX START SPEED on page 52).
For the fax to receive documents automatically, the receive mode must be set to
<FAX ONLY MODE>, <FAX/TEL AUTO SW> (Fax/Tel mode), <NET SWITCH>,
<ANS.MACHINE MODE*> (see page 28), or TAM MODE* must be set (see
page 38). If you have set <ANS.MACHINE MODE*>, check that an answering
machine is connected to the fax and that it is turned on with an outgoing
message properly recorded (see page 30).
Print out any documents stored in memory (see page 36).
Check the LCD for an error message (see page 75).
Print an activity report and check for an error (see page 54).
Make sure paper is loaded in the Multi-Purpose Tray (see the Easy Setup
Instructions).
Make sure all line connections are secure (see the Easy Setup Instructions).
