7 Connecting the Printer
7.1 Voltage Supply
Internal Battery Pack, Charging
The battery pack includes 4 NiMH Mignon (AA) cells
with 1,600 mAh. A temperature sensor monitors the
battery temperature during the charging process. A
bimetal circuit-breaker is integrated to protect against
short circuits and overheating.
The battery is connected with a 7 pin connector (9)
through the window in the battery compartment. The
battery charging voltage is connected through the
polarity protected socket (5). The plug-in power supply
for charging is part of the supplied set. It has a
connection cable with the matching connector plug
attached.
A fully charged 1,600 mAh battery will print up to app.
50 m of thermal paper with normal text.
7.2 Options
Power Management
Whenever the printer does not have data to process, it
will automatically switch to idle mode. In this mode, it
appears to be 100% active and is ready to accept
data.
Power Off
The printer is switched off by holding down the "OFF/
NEXT" button for >3 seconds. It is turned on by
pressing the FEED/ENTER button or by connecting the
charger.
Inserted rechargeable batteries require at least 3
complete charging and discharging cycles in order
to reach their full capacity. Incomplete charging
and discharging cycles during operation will redu-
ce the life span of the battery.
7.3 Charging
The GeBE-FLASH® for iOS is equipped with an
intelligent charging circuit without charging current
limiting. The current limiting is ensured through the use
of the power supply that is supplied with the printer.
The charging process is devided into three steps:
Formatting Charge
If the battery is over-discharged, it is first charged with a
low-current formatting charge in order to prevent
damage to the battery. The formatting charge is not
signaled externally. Depending on the status of the
battery, the formatting process can take about 1 to 5
minutes.
Fast Charge
As soon as the battery voltage has exceeded the
operating voltage of the printer, the printer will start a
fast charge. This is signaled through a slow flashing
STATUS LED and a message through the interface.
For empty batteries, the charging process takes about 4
hours.
Trickle Charge
As soon as one of the criteria for disconnecting has
been reached, the printer will switch to a trickle charge.
In this mode, the formatting current flows permanently.
In addition, the fast charge is activated every 8 minutes
for 20 seconds. This is signaled through permanent
lighting of the STATUS LED and a message through the
interface.
Before Installation:
Always disconnect the power in the system !
The use of a charger different from the one
supplied can cause damage to the printer.
The optimum temperature range for charging the
battery is between 20°C and 25°C, allowed range:
0°C to 30°C.
Fully discharged batteries can disturb the charging
in such a way that it breakes in at less than 30
minutes and switches to preservation charge. In this
case please start to charge again by reputting.

GeBE E + F GmbH • www.oem-printer.com • GeBE Doc. No.: SMAN-E-689-V1.1 • Thermal Printer GPT-4378-FLASH-70-iBT
9.1 Replacing the Paper
Inserting the Paper Roll
1.+2. Unwind about 10 cm of paper from the roll. Hold
the layers tightly wound, and open the lid of the printer
by slightly pulling the LEVER inside it upward.
3. Put the paper roll in the paper compartment making
sure that the outside is turned toward the printer
mechanism.
4. Close the lid by pressing on it. It will audibly snap
into place, so that the paper can be torn off at the
tear-off edge without the lid opening up, and without
the paper sliding through the print head.
Which thermal paper can be used?
The printer is specified for a paper width of
57.0 ± 0.5 mm, a roll diameter of 31 mm and a paper
thickness of 60 g/m2. The matching paper rolls
GPR-T01-057-031-007-060A (quality: 5 years) are
available from GeBE. Other papers might cause failure.
Other Paper Available from GeBE:
High Temperature Paper
is a paper that will not start to turn black before 100°C
(standard app. 70°C).
This makes it ideal for applications like parking tickets.
Adhesive Labels
are connected through perforation. There is a black
mark between the labels for correct positioning. This is
the only type of labels that can be printed with the
GeBE-FLASH® for iOS.
Long preservation Paper for Documents
is a paper that preserves its printed image for at least 5
years or max. 25 years, if stored dark and dry.
9 Maintenance
1.
3.
2.
The closed printer is protected against static discharges in accordance with the EMC guide-
lines. Since the user may come in contact with parts that are electrically sensitive, when the
printer is open (like the print head during cleaning, or the electronics during a battery
exchange), the user should make sure that all possible static charges are discharged through
sufficient grounding of the body before touching the printer (e.g. by touching grounded
objects like radiators), in order to safely avoid damage to the printer.
Which side of the thermal paper can be
printed on?
Usually, the printable side of a thermal paper roll
is on the outside.
See chapter "Error Detection and Recovery".

Description of the Key Functions
The keys can have different functions depending on the status – normal operation or print settings menu.
The time for which the button is held down is also an issue.
FEED / Enter (6)
Through this key, the printer can be reactivated from sleep mode, and the paper can be transported forward.
When the feed key is pressed, the printer will first feed one line of the set font. If the key is held down for more
than 2 seconds, it will feed continuously.
Self Test
With a self test, the inner function of the printer is tested by starting a printout. For this, the paper feed button (6)
{FEED} is held down for at least 3 seconds, while the printer is being reactivated from power-off. The interfaces
are not checked at this time. The software version and the character set are printed. For OEM, special printouts
can be activated during a self test.
OFF / NEXT Key (3)
By holding down the OFF/NEXT key for more than 3 seconds during operation, the processing of batch file T2 is
initiated. In µ-P flash, the command for power-off (after 1 second) is filed in batch file T2. This way, this key is

14 Error Detection and Recovery
Not every error means that there is a printer error that cannot be cleared by the user.
Users will save time and money by recognizing and clearing simple errors on their own.
Symptom
Possible Cause
Remedy
Paper
The printer seems to be
printing. Paper is transported,
but is not blackened.
Paper: Wrong side toward print head. Only
one side of the paper can be printed on.
Insert paper correctly. The thermosensitive side should be
turned to the outside of the roll (most of the time). Try the
finger nail test: Drag the tip of a finger nail across the paper,
pressing down. The friction heat causes the thermosensitive
side to blacken.
Power Supply
Printer can not be reactivated
by pressing the FEED key.
At the beginning of printing, the
LED goes out just briefly.
The printer only prints a few
dots in one line.
No power.
Rechargeable battery: not inserted or not
charged
Check power supply.
Recharge battery. The green LED should light up no later than
after 1 minute.
The power supply is not optimal.
Rechargeable battery: not inserted or not
charged.
Recharge battery. The green LED should light up no later than
after 1 minute.
The paper feed works, but the
self test does not.
The printer only prints a few
characters in one line. If more
is entered, it stops printing
completely.
The printer loaded over night
however it prints only few or
not.
Bluetooth®
The rechargeable battery is used up or was
not correctly loaded. Each over-discharging
damages the battery strongly and leads to a
loss of capacity.
Fully discharged batteries can disturb the charging in such a
way that it breakes in at less than 30 minutes and switches to
preservation charge. In this case please start to charge again
by reputting. Please always switch off the printers if they
lengthen are not used and please load them every 3 months.
The printer cannot be found in
the BT network.
The printer is connected over
BT but doesn't print.
Data
The printer does not react on
pressing the FEED button.
- Possible undervoltage at the BT
transmitter or the printer.
- Wrong entry of pin code
- A second accessory is connected.
- "Data Session" not open (App)
- Apple identification and authentification
failure (no paper feed after BT connect)
- Restart transmitter/printer, recharge battery.
Turn off printer and wait for app. 5 seconds.
Switch printer on and wait for app. 10 seconds.
Then search again.
- Restart printer and Apple Device and type in right pin
code (0000).
- Only one accessory is allowed to be connected at a Apple
device. Therefore switch off other accesseries and
reconnect the printer.
- Open "Data Session" according to Framework manual.
- Switch ON/OFF Bluetooth® of Apple device to cancel BT
connection or switch off the printer and reconnect the
printer again.
Incompleted graphic line stucks in printer
buffer.
Push OFF/NEXT button to complete the graphic line.
Printer can not be switched off.
Character
The printer prints wrong
characters.
Wrong character set selected.
Select character set "GBDefaultString" under menue GeBE
Printer Setup.
The following tips are meant helping you to find/eliminate a fault:
Hardware RESET: Triggered by holding down the OFF/NEXT key for more than 3 seconds.
This causes the printer to be set to the parameters in the batch file TINIT-F or TINIT-E.
Test printout: Is triggered by holding down the FEED feed key for more than 3 seconds after reactivation from po-
wer OFF (switching off with the OFF/NEXT key).
