1. Adjusting the HEAD position

Whenever the THERMAL HEAD 

 is replaced with a new one,

adjust its position for the H/C FRAME 

.

•

Procedure:

1) The screw hole for fixing the HEAD 

 in the H/C FRAME

 is made a slot as shown in the figure below. First, align

the screw hole in the HEAD 

 with the bottom area of the

slot and temporarily secure it with the SCREW 

.

2) Install the H/C 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 H/C FRAME 

. Adjust the HEAD up-

ward little by little with the screwdriver until it reaches
the desired position, and secure it with the SCREW

 (tightening torque: 6.5 kgf-cm).

2. Direction of H-SPRING 

Install the H-SPRINGs 

 so that the hooks point outward.

3. HEAD cable

Use caution to make a good connection or a deformed connec-
tor  when connecting the THERMAL HEAD 

 and HEAD ca-

bles.
