General Troubleshooting
Reception Fault
1. Cannot Receive.
a. Answering mode is incorrect.
Cause: The answering mode is set to “TEL Mode” in the Fax Settings:
System --> Admin Menu --> Fax Settings --> Ans Select .
Corrective Action: Change the answering mode from TEL Mode to other
mode (i.e., FAX Mode, TEL/FAX Mode, Ans/FAX Mode, DRPD Mode...).
b. Fax memory is full.
Cause: An attempt was made to send document data in excess of the
available memory capacity.
Corrective Action: On the receiving side, wait until the current fax job is
printed completely.
c. The printer displays some fault messages.
Cause: A fault occurred in the printer.
Corrective Action: Refer to the appropriate fault error procedures to
resolve the problem.
d. Distinctive ring pattern detection fails.
Cause: The distinctive ring pattern set for the DRPD mode is incorrect
(applicable only in USA and Canada).
Corrective Action: Check the ring pattern provided by the telephone
service provider, and select the correct pattern for fax.
e. Cannot detect Calling Tone (CNG) signal.
Cause: Communication fails in TEL/FAX mode or Ans/FAX mode.
Corrective Action: Ground the printer properly.
f. Cannot detect off-hook.
Cause: Communication fails in TEL/FAX mode or Ans/FAX mode.
Corrective Action: Set Extel Hook Thresh to Higher: System -->
Admin Menu --> Fax Settings --> Extel Hook Thresh .
A detection of an off-hook can be checked by the change of the panel
display upon the off-hook of an external telephone.
2. Problem with printing quality, such as corrupted image, lines in image, or
top/bottom cut off.
a. If copy function is normal.
Cause: Degraded telephone line connection is caused by noise, etc., or a
fault is sending Fax’s scanner.
Corrective Action: Determine whether fault is in the telephone line or at
sending Fax by trying the copy function at sending Fax.
Note
If the telephone line condition is degraded, white horizontal lines, missing
rows, and/or cut-off top/bottom may occur.
Branch connections or an incoming call (Call Waiting) may also cause
image corruption.
b. If copy function is faulty.
Cause: Dirt or fault in printer.
Corrective Action: Clean all parts of the printer or repair the printer.
