4.4.2 Procedures for processing communication problems
If the problem proves to be communication trouble, deal with it according to the following
procedures.
(1) Study the conditions at the time of trouble as closely as possible. Record or keep the
items listed below.
a) Operations at the time of trouble.
Document number, transmission mode, error occurrence timing call set-up method
(auto dialing etc.)
b) Sample of defective picture (When receiving)
c) LCD display at the time of trouble.
d) Communication management report at the time of trouble.
e) User’s name, telephone number (to contact), Fax number, model name.
f) User’s name, of the other party, telephone number (to contact), Fax number, model
name, name of servicemen in charge.
g) Frequency of trouble and error code (##100 etc.).
h) Condition of the other party’s facsimile:
Transmitted/received page number? Automatic or manual?
Error occourred? The receive condition? etc.
When visiting a user with a trouble report, a) can be known by outputting the
error protcol data (or error dump), and g) can be known by outputting the total
transacation report (or the system error data list).
(2) Test communication according to flowchart procedures appearing on the next page.
• Carry out the tests with the actual lines on each item, verify the symptoms and record
it.
• In the case of trouble with another manufacturer’s facsimile, refer to the flowchart for
troubles with other manufacture’s.
(3) Finally, process over by judging systematically all the data.
If the other party’s facsimile is that of another manufacturer and there is
nothing wrong with your customer’s machine, it is recommended that you ask
your customer to contact the facsimile user of the other party, so that the other
party’s facsimile is checked by the dealer.
“Call the service station”
in the
flowchart
(Fig.4-13)
means that problems may occur with regard to the
communication compatibility of facsimile, consult the matter with the staff in
charge at the service station. To quicken the resolving of the problem, report
the information listed in (1) above.
