2 Installation, Safety Instructions
Safety Information:
Errors and changes reserved.
The technical data given are non-committal information and do not represent any assurance of certain features.
Our terms of payment and delivery apply. All rights reserved.
Read operating manual carefully before operation.
During installation: Always disconnect the power.
Usage in accordance with the operation manual is required for product warranty.
If the user attempts to repair the product, all factory warranties will be null and void.
For technical questions please contact the GeBE Technical Support.
Installation in a Front Panel
The housing of the GPT-4352 printer can be
installed with two screws in a cut-out that is
easy to make. The contact surface is flat. The
edge of the housing juts out, covering the
space between panel and housing.
The housing is pushed from the outside into the
cut-out, and then easily screwed to two fish-
plates in the cut-out..
Two holes of 2.8 mm diameter allow the use of
M 2.5 screws.
Partial installation in a plastic casing
As shown in the picture, the printer housing
can also be installed at the edge of the device
casing. This installation variant has the part of
the printer housing that contains the paper roll
extending beyond the unit casing. This saves
room in the device casing.
Since the shapes of casings will vary, the
design provides no additional cover for
installation underneath the bearing edge.
Therefore, a clean cut-out on the side of the
casing needs to be made in accordance with
the unit design.The outer wall of the paper
storage can be used up to the slanting slot for
the fish-plate, allowing the housing to project
about 17 mm, or including the edge, approx. 19
mm.

During installation:
Always disconnect the power.
Connecting the Power Supply:
The printer can be supplied with a fixed voltage from a power supply or from a battery. Battery or power
supply are plugged in at the same connector. Through the voltage supply connection, the printer can be
supplied with voltages between 3.5 V and 7.2 V. The supply of the logic chip is produced on the board.The power
supply cable GKA-406, included in all sets, is connected to connector J4. ( 3 red wires for + 3.5 -7.2 VDC , 3 black
grounding cables, and 1 white cable for a NTC 6.8 KOhm of a NI-MHbattery) . The white wire has no function with
Li-Ion batteries or power supply . We recommend to keep the length of the line as short as possible. A line that is too
long can cause bad print quality, or even printer failure.
Attention: Avoid confusing the poles of the connections, because it would cause immediate damage to the printer..
Carefully check the connections of the power supply after the wiring is done, before you turn on the power.
Power Down: As a standard, the printer is supplied with the power down mode turned off. The power down
mode can be activated by removing resistor R37 or jumper J3 (PWDN) .
Attention :In the power down mode, the printer will sleep even when the power has been applied.
Connecting the Battery Charger:
EVAL printers have a battery charging circuit for one Li-Ion battery (3.6 V), or for 3, 4, or 5 Ni-MH cells.
For the charging, you only need an
uncontrolled plug-in power supply GNG-6V-0,5A-
U.The charger is connected to the connector J1
and through the cable GKA-409. The maximum
charging current depends on the battery voltage
(app. 0.7-0.3 A). The charging time for a1200 mA/h
battery will be app. 4 - 5 hours.
During the charging
process, the operation LED will display the
charging status. Fast charging and trickle charging
will be displayed.
ATTENTION !
Never use a fixed-voltage power supply for charging
the batteries The charging circuit is a "simple -
switch" control, meaning that the current limiting is
not done in the charging control of the printer, but
in the plug-in power supply. Use the suitable GeBE
power supply or call us for information.
Serial Interface:
The interface cable GKA-410 that is
included in all sets is connected to the
connector J2. With RS232 versions, this cable can
be connected directly to a PC. A cable with 5 single wires and one open end is available as an option.
Parallel Interface:
The printer type GPT-4352-LV-82-TTL-EVAL can be connected to the Centronics interface adapter
GCT-4382-10 through the cable GKA-407.
Infrared Interface
The printer type GPT-4352-LV-82-IR-EVAL can be connected to the infrared interface adapter GCT-4382-20
through the cable GKA-4xx. Optionally, the IR-tranceiver can also be installed directly on the board.

6 Error Detection
Not every error is a printer error.
You will save time and money by clearing simple errors yourself.
The following tips are supposed to help you with that:
Following hints might help you:
Symptom Cause Remedy
The print seems to print, but
there is no blackening
A
t the start of printing, the
LED goes out shortly
Paper inserted wrong
The power supply is not
optimal.
Insert paper correctly
Use a suitable power supply and
short lines. Check all plug-in
connections for trasfer resistances.
Since high peak currents occur
with thermal printers,even the
smallest transfer resistances result
in excessive voltage drops. In this
case, no power supply would be
strong enough. A bufferingwith
capacitors is possible, if the power
supply is only slightly too weak,
and large capacitors are used (e.g.
4,700 ±F) .
The printer only prints a few
dots in one line.
The paper feed works, but
the self test does not.
The printer only prints a few
characters in one line.When
I enter more, it won't print at
all.
The print-out is incomplete
after a few characters
The printer buffer is "run
over" (256 bytes), so data
are getting lost .
Solution: Check or start using
handshake. (XON/XOFF, or hard-
ware). If necessary, lower output
speed, e.g. go down to 1,200 baud.
See MAN-D-400, "Interface
Settings"
The printer prints wrong
characters.
RS232 instead of TTL
interace or reverse.
(Characters of the upper
area are printed).
Wrong baud rate was
selected. (A lot of"?" are
printed)
Use correct interface
Set baud rate through solder
bridges or TINIT
Bad ground connection of
the printer. If the printer is
not grounded right, a part
of the printing current will
flow through the interface,
causing a voltage riseand
therefore, a data
falsification.
Host sends a break signal
after print job (printing only
"?" )
Repair ground connection.
Turn off "framing error ". See MAN-
D-400 "Interface Settings"
My Centronics printer works
with a PC, but not with my
machine.
Printer is electronically not
compatiblewith host.
Measure level of the line that is
reporting the error. GeBE can
adjust this.

Operation 5
Which thermal paper is suitable?
The printer is specified for a paper width of 57.5 Ø 0.5 mm,
with a weight of 60 g/sq m. GeBE is offering a suitable paper
roll as part of the standard program ( GPR-T01-057-031-007-
060A). Other papers may cause trouble. Thermal papers that
are resistent against water, grease, or alcohol are available
for special applications. We will gladly assist you in your
selection of the suitable thermal paper.
Which side of the thermal paper can be printed on ?
On the paper roll, the outside is always the side to print on. If
you should have any doubts, just do the finger nail test. The
thermosensitive side will turn black under the pressure of a
sharp object..
How do I Insert the Paper ?
Use paper rolls with the paper coated on the outside, 57 mm Ø
0.5mm with a winding diameter of 31 mm.
1. Unwind about 10 cm (4") of paper from the roll. Keep the
layers wound tightly.
2. Öpen the printer cover by slightly pressing the lever in the
cover up. The print roll gets lifted from the mechanism
together with the cover. The cover can now be opened easily.
3. Insert the paper roll in the paper
supply, so the outside
shows toward the printer mechanism. Only the outside is
printable.
4. Close the cover by applying strong pressure. You will be
able to hear it snap shut. Now, you can rip off the paper at the
tear bar without the cover opening again and the paper sliding
back into the printer.
The Control Elements of the Printer:
Paper feed button: This button wakes up the printer
from the sleep mode and feeds the paper.
Self test: Before a connection between printer and host (PC)
is established, the function of the printer can be tested by
starting a self test. Keep the paper feed button pressed while
turning on the power supply. When the feed button is
released, the self test will begin. The test will only check the
functions of the inner circuit, but not the interface.
Status LED: This LED shows the status of the printer
during operation, and - if it is equipped with a charging
circuit and a battery - the charging status of the battery
during the charging process. See "Messages of the Printer".
