1. Model Name: 
MX6500N – MX7500N, MX-M1054 – MX-M1204 
 
2. Outline:
   
If magnification adjustment and off-center adjustment for engine are performed by  
 
 
 
executing "BK-MAG ADJ" and "SETUP/PRINT ADJ" in Sim 50-28 while auto-centering  
 
 
 
adjustment is functioning, these features conflict each other that it may trigger off-center  
 
 
 
shift. Do not execute "BK-MAG ADJ" and "SETUP/PRINT ADJ" under the condition. 
 
 
 
 
 
 
 
 
 
 
 
 
3. Description:
 
<<Description on auto-centering feature>> 
 
 
   
 
There are two settings "SWT1" and "SWT2" in Sim 50-10. 
 
  
 
 Auto-centering feature is enabled if either one or both settings is set to "1".  
While auto-centering adjustment is enabled, paper transport position for the paper feeding 
option installed to a device is automatically detected. Then beginning position for writing by LSU 
is adjusted so that the images are printed on proper position. 
 
 
 
 
<<Expected failure and countermeasure>> 
 
 
 
 
If "SETUP/PRINT ADJ" (Print position adjustment for paper feed options) in Sim 50-28 is  
 
 
 
executed while auto-centering adjustment is enabled during the machine installation, the  
 
  
 
adjustment value is changed before print position is determined according the auto-centering  
 
 
 
adjustment. The print position may shift as soon as the auto-centering adjustment is executed. 
 
 
 
To avoid this problem, the value in "MAIN-**" and "SUB-**" in Sim 50-10 need to return to the  
default value. If it is necessary to adjust print position while auto-centering adjustment is 
enabled, change the value in ”MAIN-**” and ”SUB-**” in Sim 50-10. Print position is controlled 
based on  the set value while reflecting the auto-centering control. 
 
  
 
To adjust "BK-MAG ADJ" in Sim 50-10, it is necessary to follow the adjustment steps below and  
 
  
 
execute auto-centering adjustment again.
