[Cautions to be taken when reinstalling]
1. Adjusting the HEAD position
Whenever the THERMAL HEAD 
 is replaced with a new one,
adjust its position for the HEAD FRAME 
.
Procedure:
1) The screw hole for fixing the THERMAL HEAD 
 in the
HEAD FRAME 
 is made a slot as shown in the figure
below. First, align the screw hole in the THERMAL HEAD
 with the bottom area of the slot and temporarily secure
it with the SCREW 
.
2) Install the HEAD FRAME UNIT 
 on the HOUSING 
.
3) Adjust the HEAD position and make sure that heating
element of the HEAD 
 is most properly positioned, by
performing a printing test. Do not adjust the Head position
during printing; otherwise the HEAD might break down
due to friction.
<Procedure for adjusting HEAD position>
(1) Insert a flat-bladed screwdriver into the adjustment
hole C in the HEAD FRAME 
. Adjust the HEAD
upward little by little with the screwdriver until it
reaches the desired position, and secure it with the
SCREW 
 (tightening torque: 6.5 kgf-cm).
4) If there is a difference in darkness in print between the
receipt and journal, insert the angle A’s spacer into the
gap between the HEAD FRAME unit and the thermal
head as shown in the figure below.
2. Direction of H-SPRING 
Install the H-SPRINGs 
 so that the hooks point outward.
Fig. 7
3. HEAD cable
Install the 9-pin connector to the right end of the THERMAL
HEAD   and the 10-pin connector to the left end.
Use caution to make a good connection or a deformed connec-
tor  when connecting the THERMAL HEAD 
 and HEAD ca-
bles.
