An error code is used to indicate a fault in a machine, and is indicated in the machine's LCD or reports, showing the nature (symptoms) of the fault. Using the error
code, the user or the service man can readily find out how to correct the fault by simply referring to the User's Manual or service manual.
An error code may be either of the following two types:
User Error Codes
A fault indicated as a user error code is one that can easily be corrected by the user, as by operating the machine. It takes the form of "#+number."
Service Error Codes
If a fault calls for a service man for correction, it is indicated as a service man error code in the form of "##+number" or "SYSTEM ERROR E+number."
Memo
A service error code expressed in the form of "##+number" will not appear on the LCD, Error Tx Report, or Activity Report while the machine remains
in factory default state. To check a service error code, shift bit 0 of service soft switch #1 SSSW SW01 to '1'.
Memo
Display only the error codes which are newly incorporated in this machine as well as which require remedies unique to the product. For the causes and
countermeasures of other error codes, refer to the separate G3/G4 Facsimile Error Code List (Rev. 2).
