Unable to communicate
(general fax)

Symptom
When the Authentication/Accounting feature is used and you send
a fax directly from the computer, you must set the user ID and
password registered on the device to the fax driver.
Reference
Clean the document glass.
Reference
If the density is appropriate, adjust the fax density.
Reference
Check if the recipient's device has no problem.

recipients' display or activity reports is wrong, correct the local

Reference
Turn off the Transmission Header Text feature.

Symptom
The device is equipped with connectors to which to connect phone
lines. Communication is enabled only when the phone line is
connected to the correct connector. When the cable connection is
correct, the On-hook feature allows you to call via general lines.
Use a telephone near the device to check whether you can make a
phone call. If the phone call is disabled, the problem is in the phone
line, not in the device.
The device cannot receive a fax when turned off. Switch the power
on.
Load paper in the device to receive faxes.
Check the touch screen display. If it says that a paper jam occurs,
remove the jammed paper.
Reference
The device cannot receive a fax in the System Administration
mode. Exit the System Administration mode.
For details on the Authentication/Accounting feature, refer to "Authentication and
Accounting Features" (P.355). For details on how to directly send a fax from the
computer, refer to "Direct Fax" (P.149).
Refer to "Cleaning White Chute and Constant Velocity Transport Glass" (P.403).
Refer to "[Lighten / Darken]" (P.150).
Image quality may be affected by a problem of the recipient's device,
not just by a problem of yours.
Refer to "[Local Terminal Information]" (P.288).
Refer to "[Transmission Header]" (P.152).
Refer to "Paper Jams" (P.451).
