Troubleshooting 

 
The following tables show possible remedies for various symptoms that might occur. Symptoms 
are given in the left column, and the corresponding remedies in the right column. 

Notes:

  1. When parts are replaced, refer to Chapter 3 “Disassembly and Maintenance”. 

 

2. For the location of each connector, refer to “

4-2-6 Connector Location

". 

 

4-2-1.  Problems in Powering Up the Printer 

 

Symptoms 

Checks 

Remedies 

No power to the 
printer 

 
 
 
 
 
 
 
 
 
 

1.  Check voltage on the input power line. 

Acceptable supply voltage:   
   100 to 240V AC 

 
2.  Is the power cord loosely connected? 
 
 
3.  Is the “SA Power Cable” firmly 

connected between the “Unit Power 
Supply” and the “SA Main PCB” (J13)?

 
4.  Is the “FFC Opepane” connected 

between the “SA Main PCB” (J3) and 
the “SA Opepane PCB” firmly? 
If it is not connect or is inserted upside 
down, no LED lights even if you turned 
ON the power. Also, nothing is 
displayed on the LCD. 

 
5.  Failure in the power supply circuit. 

 

1.  Supply correct voltage. 
 
 
 
2.  Connect it firmly. 
 
 
3.  Connect it firmly. 
 
 
 
4.  Connect it firmly. 
 
 
 
 
 
 
 
5.  Replace the “Unit Power Supply”.
