9.1 ERROR INDICATION 

To help the user or the service personnel promptly locate the cause of a problem (if any), the  
facsimile equipment incorporates the self-diagnostic functions which display error messages for  
equipment errors and communications errors. 
For the communications errors, the equipment also prints out the transmission verification report  
and the communications list. 

9.1.1 Equipment 

Errors 

If an equipment error occurs, the facsimile equipment emits an audible alarm (continuous beeping)  
for approximately 4 seconds and shows the error message on the LCD.  For the error messages, see  
[ 1 ] below. 

To display detailed error information, use maintenance-mode function code 82 described in  

Chapter 8, Section 8.4.16

 (that is, make the equipment enter the maintenance mode and then press  

the 

8

 and 

2

 keys).  Following the MACHINE ERROR, one of the error codes listed in [ 2 ] will  

appear on the LCD.
