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

2. Direction of H-SPRING
Install the H-SPRINGs
so that the hooks point outward.
