ADJUSTMENT Overview 162
5.1  Overview
This section describes the procedure for adjustments required when the printer is 
disassembled and assembled for repair or service.
5.1.1  Required Adjustment
If you remove or replace the specific part in your service/repair, you have to perform 
the appropriate adjustment as listed Table 5-1 below.
In this printer, it is necessary to perform appropriate adjustment in order to maintain 
consistent printing function and quality, eliminate differences of each printer 
mechanism’s characteristics. Therefore, in case that the combination between the 
printer mechanism and the Main Board changes or the Print Head is replaced during 
the repair service, you must input the correct adjustment value into the EEPROM on 
the Main Board by using the Adjustment program.
