2. Telephone Screening
2.1 Inquiry from a User
Most problems end user inquiries are a result of the following. Therefore, first ask the nature of
the trouble (in detail) to seek the cause. These questions can lead to a speedy resolution of the
trouble without the need for a service technician.
• Simple misoperation
A trouble caused by a simple misoperation can be solved by the user alone with an
appropriate instruction through the telephone.
• A failure with the telephone line
The machine’s condition can be checked by the user’s operating sending/receiving
documents to/from another facsimile unit.
• A failure with the other party’s machine
The other party’s machine’s condition can be checked by the user’s operating sending/
receiving documents from/to the user’s machine.
Also, by verifying the error code in the LCD display or on the Journal with the user, the nature of
the trouble can be confirmed. This information is important in finding the cause of trouble. When-
ever it can be obtained from the user, respond on the telephone by tracing the “2.4 Flow Chart
Recommended for Telephone Screening.” This will help the service technician to be prepared
for the necessary service requirements.
