Transmission Fault

Phaser 6180MFP Multifunction Printer Service Manual
Locating a fault could be problematic because a Fax is composed of multiple
blocks.
First, try using the copy function. If the copy function's printing results are
correct, the probability of a fault in the Fax itself is low. The fault is likely in the
telephone line or receiving Fax. If the fault is in the telephone line, first retry
sending the data. If there is no improvement, contact the telephone company.
If the copy function's printing results are incorrect, it can be determined if the
fault is in the scanner or printer by operating each unit separately via a
computer.
1. Problem with printing quality at receiving Fax, such as corrupt image,
lines in image, or top/bottom cut off.
a. If a copy is normal.
Cause: Degraded telephone line connection is caused by noise, etc., or a
fault in receiving Fax's printer.
Corrective Action: Determine whether fault is in the telephone or at
receiving Fax by trying copy function at receiving Fax.
Note
If the telephone line degraded, white horizontal lines, missing rows, and/
or cut-off top/bottom may occur.
Branch connections or incoming call (call waiting) may also caused image
corruption.
b. If copy function is faulty.
Cause: Dirt or fault in scanner.
Corrective Action: Clean the document glass or repair the scanner. If
the original is being sent from the ADF, try making a copy with the original
placed on the document glass. If this resolves the problem, the fault is in
the ADF.
2. Cannot dial.
Cause: No connection. Incorrect setup of dial type and/or line type.
Corrective Action: Reconnect the telephone line. Reset the dial type
and/or line type to correct the settings.
Note
If the telephone line condition is degraded, white horizontal lines, missing
rows, and/or cut-off top/bottom may occur.
Branch connections or incoming call (call waiting) may also cause image
corruption.
