(6) Solder two lead wires of the eject motor ASSY.
Note1: When replacing the thermal head, change the solder point on the main PCB
according to the resistance value of the thermal head. When the solder point is
changed, verify with a multi meter whether solder on the unsolder point is removed
properly.
Note2: Be sure to use the lead-free solder. (Set the temperature of the solder iron to 350 ° C.)
