Is a surge-protection device installed?
◦
A surge-protection device might be installed between the telephone jack and the product to
protect the product from electrical power that passes through the telephone lines. These
devices might cause some fax communication problems by degrading the quality of the
telephone signal. If you are having problems sending or receiving faxes, connect the device
directly to the telephone jack to determine if the problem is in the surge-protection device.

Is a telephone company voice-message service being used?
◦
If the messaging service rings-to-answer setting is lower than the product rings-to-answer
setting, the messaging service answers the call and the product will not detect incoming faxes.
If the product rings-to-answer setting is lower than that of the messaging service, the product
answers all calls and no calls will ever be sent to the messaging service. The only voice-
messaging system that can be used with the product is a standard telephone-answering
machine.
●
Is a standard telephone-answering machine installed?
◦
An answering machine must be connected to the port that is labeled with the telephone icon
(or it can be shared on the same telephone-line extension). Set the product rings-to-answer
setting for at least one ring more than the number of rings that prompts the answering machine
to answer a incoming call. For example, if the answering machine is set to answer calls after
three rings, set the product rings-to-answer setting to four rings.
NOTE: If an answering machine is connected to the same telephone line but is connected to a
different jack (for example, in another room), it might interfere with the product to fax reception.
Table 7-4 General fax troubleshooting
The document stops feeding into the ADF while the product is sending a fax.
Cause
Solution
A page cannot exceed 356 mm (14 inches). Attempting to load
a page longer that 381 mm (15 inches) will cause the fax to
stop.
Press Cancel on the control panel. If the page is jammed, clear
the jam. Fax the document by using multiple pages (each less
than 356 mm [14 inches] in length) instead of one long one.
The page is too small. Press Cancel. If the page is jammed, clear the jam. Make sure
that the page is at least 89 x 44 mm (3.5 x 1.75 inches) in size
before you load it into the ADF. If the page is smaller, use a
carrier sheet or affix the page to a larger sheet.
The fax activity log is printing at inappropriate times
Cause
Solution
The fax activity log settings are incorrect. Print a configuration report and check the fax activity log
settings. Set the fax activity log settings at the product control
panel.
NOTE: The fax log might be set to automatically print. Use
the product control panel to change the setting.
