Other problems

•
Branch connection (parallel connection)
During fax reception, if the handset of another telephone on a branch connection is
-
lifted, the received image may be corrupted or a transmission error may occur.
Branch connections may also interfere with caller identification, call waiting, and the
-
receiving operation of connected telephones.
•
Call waiting
If a call comes in during fax sending or reception, the image may be corrupted.
-
•
DSL (Digital Subscriber Line)
DSL uses existing telephone lines to deliver high speed transmission. Because the
-
line is used for voice and data transmission, various problems may occur.
Problems such as noise during spoken conversation, low sound volume, and
-
misdialing are possible.
Replacing the splitter (line filter) may improve the problem.

For Training Purposes Only
Cause: Degraded telephone line connection caused by noise, etc. or a
problem with the sending fax's scanner.
Corrective action: Determine whether the problem is in telephone line or at
the sending fax by trying the copy function at the 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.
Cause: Dirt or a problem in the printer.
Corrective action: Clean all the parts of printer, or repair the printer.
