7.9 Reception Problem
This section explains how to localize the cause of problems occurred after completion of connection with a
remote station.
Before beginning: Printout the Activity Report.
• Look for common failure items. For instance, is one particular country, area code or phone number
always causing the problem?
• If possible, substitute the "defective" OKIFAX unit with a known good facsimile unit. If the trouble
persists, there may be a problem with the line or at the receiving end.
• Check the OKIFAX User Functions, Dialing Parameters and Technical Functions.
Perform the High-Speed Modem Transmit Test (refer to section 7.13). If this test fails, perform
replacements listed below until problem is corrected.
Data communicaiton problems could have many different causes. It would be almost impossible to design
a RAP to cover all possible situations. Therefore, once you have performed the above listed steps, replace
the following assemblies in the order listed:
1) Modem board. (OKIFAX 2350/2450 only)
2) MCNT board.
