2 Description
Small and Compact
The design of most kiosk terminals is continuously getting smaller. The printer INFO Compact Plus with variable
paper holder may be the ideal solution. The paper is unwound and transported down from an axle into the printer
mechanism. A fastener on the side prevents the paper roll from slipping off the axle. An optionally available near-
paper-end sensor reports the paper status. An adjuster allows setting of user-defined paper widths (see chapter
3, 11) until maximum 60/82 mm paper width.
Fast Printing
Various applications - especially in the public domain - require considerably faster data output. The new GeBE
INFO Compact Plus printer prints up to 200 mm per second, counteracting any impatient pulling on the paper by
the user and therefore, avoiding costly damage of printer mechanism or cutter.
GeBE Controller
Controller GCT-4692/4693, developed by GeBE and controlling these fast printouts, has been combined with a
robust printer mechanism to create a new product. The mechanics of this printer mechanism originates from the
established industrial printer module family INFO from GeBE. In addition to its speed, this fast, compact INFO -
printer for the kiosk area stands out due to high reliability, its service and application friendlyness.
Easy Customization through Software
Settings such as blackening, text size, RS232 control, etc. can be set up by the user. On request, command and
character set adaptations can also be performed at the factory.
Downloads
Firmware, fonts, logos, macros, settings, etc. can simply be sent as a file from the PC through the active inter-
face to the printer, where they are stored permanently.

6 Installation
6.2 Installation as a printer with paper catch
Select the mounting plane according to paper
curvature and arrangement of the paper catch. The
paper holder can be mounted on the right side of the
printer (see chapter 6.3).
Important notes regarding paper catch solutions:
1. Electrostatic charging of the tickets
Tickets rubbing against plastic, ungrounded surfaces
etc., may cause electrostatic charging of the ticket
which may lead to the ticket getting stuck in the shaft.
Proposed solutions:
- Potential equalization of all metallic surfaces
- Use of electroconductive "brush" at paper outlet
- Use of antistatic paper
2. Humidity in the paper
Temperatures at or below the dew point cause the
paper to absorb humidity, which may result in the
paper getting stuck in the shaft.
Proposed solutions:
- Air-condition of the device
- Use of top coat paper
6.3 Installation as front panel printer
The GPT-4672/4673 is installed with mounting tabs in
accordance with the application.
The transission of paper between the printer
mechanism and the front slot requires a guide that can
even be about 1 cm shorter than the printed receipt,
provided that the length of the receipts always remains
the same. This prevents the paper from being
obstructed for longer periods of time during the print.
process.
6.1 Installation using mounting tabs M4
The GPT-4672/4673 can be installed vertically with four
mounting tabs. For a service-friendly disassembly, the
printer can be taken off by pushing it up after
untightening the srcews (M4) .

10 Label and ticket print
10.2 Printing labels and tickets
10.2.1 Label mode
The printer firmware utilizes hole-marks or black marks for exact synchronization of print line and label or ticket
start. The printing of a label / ticket is concluded with a form feed (FF) <12d> command. This command causes
the printer to paper feed until the black mark sensor recognizes a control mark + a defined distance „B“
(parameter 19). This also works in case the control mark has passed the black mark sensor during printing. „B“
should be selected such that the next line prints at the beginning of the new ticket.

Label print12
GeBE E + F GmbH • www.gebe.net • GeBE Doc.No.: SMAN-E-657-V1.4 Thermal Printer GPT-4672/4673
Parameter 19: Standard Setting := 0d
Label-distance print head <-> Black mark sensor in li-
nes (1/8 mm):
This parameter controls how long printing commences
after a black mark has been recognized. This distance
includes printing and form feed until the ticket ends.
Therefore it is not imperative for the black mark to be at
the beginning of the ticket. This setting permits to
“move” a black mark to any position.
Parameter 20: Standard Setting := 3d
Label-Flags
Bit 0: enable label mode (1: label mode on)
Bit 1: 0: internal PE sensor
1: AUX1 used for label control
Bit 2: 1: increases P19 value about 265 lines
Bit 3-7: future use (has to be set to zero)
Parameter 39: Standard Setting := 0d
This parameter indicates which kind of sensor is
connected (reflex/fork light barrier).
Bit polarity:
0 = Reflex light barrier
1 = Fork light barrier
Sensor Param-Bit
NPE Bit 0
AUX1 Bit 1
AUX2 Bit 2
AUX3 Bit 3
AUX4 Bit 4
Cutting:
A (feed „A“) has to be added after the FF command if
the ticket needs to be cut after printing. The
subsequent area „D1“ cannot be used for printing
because it is part of the next ticket.
Hint 1: Printing of the next ticket can commence
during the feed to the Cut-Position!
Hint 2: The GPT-46xx is capable of advancing paper
to be cut and subsequently retracting the
paper to the next printing position. The sensor
must not „see“ any black marks during this
process.
Distances:
sensor, print head, cutter
in mm GPT-4673 GPT-4672
B: sensor - print head 15 13,5
A: print head - cutter 13,5 12
Label mode can be configured by means of several
printer parameters. For standard tickets, only the
parameter 20 needs to be changed from a decimal
value of 0d to 3d. Parameters are saved to user settings
by using the command format:
<ESC>V<Param><Value>.
Setting label control:
Parameter 16: Standard Setting := 254d
Label length in mm:
This setting indicates how long the device looks for
black marks before the search is canceled. This value
should be significantly longer than the length of the
label or ticket.
Parameter 17: Standard Setting := 16d
Length of recognition of black mark in lines (1/8 mm):
This parameter controls how many black mark lines has
to be recognized that a black mark becomes valid. For
instance, black marks will be recognized quickly if the
parameter is set to a low value, such as 4d. On the
other hand, some elements other than black marks,
such as pre printed text, might also be recognized as
black marks. The standard setting 10d will ignore pre-
printed elements of < 1mm.
Parameter 18: Standard Setting := 80d
Length of black mark or distance to PE-Recognition in
lines (1/8 mm):
This parameter controls after how many paper-end lines
the paper-end condition is met. The PE-Error is deleted
as soon as new paper is detected. A line feed is
necessary, and the value should be about 1 mm larger
than the utilized black mark size. Too large of a value
will cause a delay in PE-recognition.

11 Cleaning
10.2.2 Control black marks
Control black marks must be printed using infrared
absorbing color in the range of 910-950 nm. Optical
density should be a minimum of 1.0.
After the printer received a form feed command, the
ticket will be positioned to the black mark position +
the length set under Param 19.
This also works in case the control mark has passed
the black mark sensor during printing. Therefore, the
control mark can be set at random within Param 19.
See illustration.
„Final Position“ (P19 := 0) is defined by the distance
between print position and black mark sensor.
After larger print efforts, depending on the paper quality and
adverse environmental conditions, it may be necessary to clean
the print head, sensor, and the platen roll, especially, if some
areas are no longer printed properly.
1. Open printer mechanism by slightly pressing metal lever
upwards.
2. Flap downwards paper carrier roller incl. position mark sensor.
The printer mechanism is now open.
3. Blow forcefully into printer mechanism and onto position mark
sensor, in order to remove coarse dust.
4. Use a small brush to clean paper carrier roll, sensor and
tear-off edge from dirt.
5. Soak Q-tip in isopropanol (IPA) and clean the print bar.
Other stubborn debris can also be removed with a Q-tip (IPA).
Never use sharp objects for cleaning. This might cause damage to the
print head.
Do not touch the print head. This might cause damage through
electrostatic charge.
On principle the printer has to be kept dust-free.

12 Troubleshooting and recovery
Not every failure means that there is an error that cannot be cleared by the user himself. You will save time and
money by recognizing and fixing simple errors on your own. The following tips are meant to help you with this:
Hardware RESET: Activated by unplugging and reconnecting the power supply after a short break.
This sets the printer in accordance with the TINIT-F and/or the TINIT-E in the batch file.
Symptom
Possible Cause
Remedy
The printer seems to be
printing, but the paper is
not blackened.
The printer only prints a few
characters in one line. If
more is entered, it stops
printing altogether.
Paper inserted incorrectly.
The power supply is not optimal.
Insert paper correctly.
Use sufficiently sized power supply and short feed
lines. Check all connections for possible transfer
resistances. Since high peak currents occur with
thermal printers, even the smallest transfer
resistances can result in intolerable voltage drops. In
this case, no power supply would be strong enough.
Buffering with capacitors is possible, if the power
supply is only too weak by a small margin and large
capacitors (e.g. 4,700 µF; high switching
capability) are used.
The printer only prints a few
dots in one line.
After a few characters, the
printout starts to be
incomplete.
The printer prints the wrong
characters.
The printer buffer is "over-run" (256 bytes),
causing loss of data.
Solution: Use or check handshake. (software: Xon/
Xoff or hardware).
If necessary: slow down transmission speed, e.g.
down to 1,200 baud.
(See MAN-E-559 Interface Settings)
TTl instead of RS232 interface or
vice-versa. (Characters of the upper area
are printed).
Bad ground connection that causes a part
of the printing current to flow through the
interface cable. This leads to an increase
in potential there, which results in data
corruption.
Use correct interface.
Repair ground connection.
Printer works with a PC, but
not at the machine.
Printer is electrically incompatible with the
host.
Measure level of the line signaling the errors.
GeBE can adjust this.
