Transmission Fault - Dell 3115cn Service Manual

3.3 Transmission Fault

1) Problem with printing quality at the receiving fax, such as corrupt image, lines in image, top/bottom
cut off.
a) If copy function is normal
Cause: Degraded telephone line connection caused by noise, etc.; or a fault in the receiving fax's
printer.
Corrective Action: Determine whether the fault is in the telephone line or at the receiving fax by try-
ing copy function at the receiving fax.
If the telephone line condition is degraded, white horizontal lines, missing rows,
and/or top/bottom cut-off may occur.
Branch connections or incoming call (call waiting) may also cause image
corruption.
b) If copy function is faulty
Cause: Dirt or fault in scanner.
Corrective Action: Clean the platen glass or repair the scanner. If the original was sent from the
ADF, try executing a copy with the original placed on the platen glass. If this solves the problem, the
fault is in the ADF.
2) Cannot dial
Cause: Incorrect connection. Incorrect setup of dial type and/or line type.
Corrective Action: Correct the connection. Reset the dial type and/or line type to correct settings.
