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 Adjustments
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.
