4-5. ASSEMBLING THE UNIT
The unit should be assembled by simply reverse
the disassembling steps, taking care not to
damage any cables.
GROUND WIRE
Ground wires are connected as following figure.
To
avoid
the
damage
of
the
static
electricity
or
to
protect
against
the
noise
interference,
these
two
ground
wires
must
be
connected
to
the
drawer
by
screw-(A).
SPECIAL INSTRUCTION
@ CABLE/WIRE FORMING
Any
cables
or
wires
especially
for
operator
and
customer display cable must be formed far from
the
power
transformer,
because
of
the
safety
standards
or
the
protection
against
the
noise
interference.
@ CLEARANCE FOR THE REWIND MOTOR
The
shaft
of
rewind
motor
for
journal
paper
has
attached
the
spacer.
For
smooth
paper
winding,
the
clearance
between
the
motor
and
spacer
is
0.5
mm.
@ MICRO SWITCH FOR THE DRAWER
When
the
machine
will
be
attached
the
drawer
without
the
micro
switch,
the
Short
circuit
jumper
wire
must
be
installed
between
No.
4
pin
and
No.
5
pin of connector CP 10.

5. MACHINE INITIALIZE
There are two (2) types of recover methods from the
machine interlocking and several methods for
machine initialize are available.
: HARD RESET
: EMERGENCY RESET
: LP.L (Initial Program Loading)
: Auto-Loading Key layout
: GT’s and Z counter Initialize
: RESET (Z) report

@ HARD RESET
Even after the AC power is disconnected, the VCM
voltage can still be supplied by the Ni-Cd battery to
holding the contents of memory. When the AC power
is recovered, normally RESET signal will not
generate from the reset circuit (IC8), because of the
VCM keeps over +2.4 V. In other words, the VCM
voltage must be under +1.2 V to generate the
RESET signal for CPU (IC1).
Note : VCM = +1.2V ~ +2.4 V (transiting level)
The following operations is explained enforced
generation of RESET signal.
@ HARD RESET OPERATION
(1) Unplug the machine from AC outlet.
(2) Removing the cabinet.
(3) Cut the Jumper wire marked “BAT-T” on the
M1 P.C.B located near the symbol mark of
Ni-Cd battery.
(4) Check the VCM if the voltage is under +1.2
V. If not, make a short circuit between VCM
and GND line by a tweezers.
(5) Plug in the terminal and make sure that the
printer will move for a moment.
(6) Solder the “BAT-T” wire again.
ATTENTION: Do not short any other
circuit, because the AC
power is supplied.
(7) Replace the cabinet.
(8) Programming the terminal.
