2 - IMPORTANT NOTES ON THERMAL PRINTER HANDLING
In order to preserve the life of the printer, it is necessary to keep in mind some precautions on the
handling of the K 55 printer. Please read carefully the following points in order to make a good use of
the printer.
2.1 - SAFETY PRECAUTIONS
•Before using the printer, read carefully section - INSTALLATION.
•NEVER connect the external power supply with the wrong polarity. This could permanently
damage the printer.
•Turn off the printer immediately if it produces smoke, a strange smell or an unusual noise. Keeping
on using the printer could cause fire. Unplug the equipment immediately and contact your official
distributor.
•NEVER connect cables with different connectors from the ones mentioned in this manual. Failing
on doing so could permanently damage the printer.
•Use a power supply whose output voltage is within the specification range stated in this manual.
Over voltage can permanently damage the printer. Under voltage can cause malfunctions.
•NEVER wet K 55 thermal printer with water or any other liquid. If any liquid is spilled inside the
equipment, unplug the power cable immediately and contact the technical service.
•Make sure the printer is on a steady, securely fixed surface. If the printer falls down, it could break
or damage.
•NEVER use the printer in high humidity or in locations with high risk of fire.
•NEVER place heavy objects on top of the printer and never lean on it.
•NEVER put any object inside of the printer, as it could cause hardware damage on it, such as
short-circuit, print head breaking or general failure of the printer.
•NEVER shake the printer.
•NEVER disassemble or modify the hardware of the printer.
•NEVER try to repair the printer. Please contact your official distributor in case of failure.
•As the printer contains electromagnets (inside of the motor), it should not be used in excessively
dirty environments or places with dust or metal particles.
•NEVER print without paper loaded or without the cover closed, as the thermal print head life can
be highly shortened.
•NEVER pull the paper out when the cover is closed. Use the paper advance button instead.
•Avoid touching accessible parts with metallic objects, such as screwdrivers or tweezers, the print
head thermal elements as well as the electronic printed circuit. They are delicate parts.
•NEVER touch with bare hands the areas around the print head and the motor surface as they
become very hot during and just after printing; wait 15 seconds after printing to let them cool down.
•NEVER touch the surfaces of the print head thermal elements or the electronic printed circuit, as
dust and dirt can stick to their surface and cause damage by electrostatic discharge. Moreover,
some electronic components can get very hot during operation.
•The thermal paper contains Na+, K+ and Cl- ions that can cause harm to the print head elements.
Therefore, use only the specified paper.
•If the printer has not been used for long period of time and the paper was loaded, the paper could
become deformed by the drive roller pressure. It is recommended to make it advance at least 30
mm before printing again.
•For safety reasons, unplug the printer if it is not going to be used over a long period of time.
•Do not print ontinuously (without stopping) for more than 6 minutes.

2.3 - CLEANING PROCEDURE AND PRECAUTIONS
Paper dust, paper chips, and thermal chemicals attached to the heat elements of the print head
and the platen may reduce print quality. In order to clean the thermal print head, proceed as indicated by
the following steps:
1.- Unplug the power supply cable and open the cutter unit.
2.- Pull the paper lever in order to release the platen.
3.- oak a cotton sponge in alcohol (ethanol, methanol or
IPA), and rub it gently along the thermal head in order to
remove the possible accumulation of paper particles.
4.- Wait for alcohol to evaporate before inserting the paper
roll and closing the cover.
FENIX recommends cleaning the thermal print head
periodically (every 2 or 3 months) in order to keep an
optimal print quality.
Fig.2.1. Thermal print head cleaning.
The print head may be hot after printing.
Make sure it has thoroughly cooled down before proceeding to clean it.
Never touch the thermal elements of the print head with your hands.
Never use metallic or piercing elements to clean the print head, as they could scratch it.
5.- To clean the rollers and paper sensor of
the presenter, apply compressed air over
them for a few seconds, eliminating dust
and paper chips.

4 - INSTALLATION
4.1 - INSTALLATION CONSIDERATIONS
The K 55 is designed to be fixed in a bigger case or structure or another kind of appropriate
chassis. A wrong installation may cause many issues like paper jam, difficult maintenance of the printer,
difficulty in changing the paper roll, etc. Moreover, a correct installation can prevent the printer from
being damaged by external agents, such as weather or vandalism.
The basic points that a correct installation must follow are:
•mooth exit of the ticket. Prevent problems with static electricity due to the nature of the
used materials. Be sure to make a good earth connection.
•Allow enough room and accessibility to reach the maintenance procedure points in case it is
needed. Take notice all user accessible parts in the printer:
–Printing Head /presenter unit.
–Paper roll location.
–Connectors.
–Led and push-button.
•Fix the K 55 printer to the chassis by using four screws (Ø5mm maximum) as shown on the
pictures below. It is recommended to implement some system to allow the printer to be
moved backwards when accessing the printing head or presenter unit. Below it is shown
how to fix the printer onto a detachable or sliding tray or practice fixing slots on the
supporting base, so that the K 55 can be moved backwards and forwards for easy
maintenance.
Printer + base move jointly. Base fixed. Printer moves.

4.1.1 - Outer ase stru ture
The following points must be assured when designing the outer case:
•If the paper jams, it should be possible to open the presenter; it is recommended to
implement some system to allow printer retraction as show in previous figure and provide
enough space to open or close de presenter.
•It is recommended, also, to leave a sufficient gap at the paper roll side to allow the printer
being removed for servicing.

4.2 - KS55 CONNECTORS
On the K 55 could be found the following connectors:
Fig.4.5. U B or ERIAL R 232 interface connectors.
4.2.1 - Power supply onne tor
The K 55 is powered by an external power supply by means of 3-pins connector shown below.
Verify power supply voltage before connecting the printer.
Fig.4.6. Power supply connector J1.
Use a 3-pin DC ja k TCS-7960-43-2010 (HOSIDEN) or equivalent. ( ee APPENDIX – HOW TO
ORDER-ACCESSORIES).
NOTES:
(1) The K 55 requires one power source: VCC (24VDC) for driving the thermal head and
motor.
(2) If the number of dots that are energized at the same time is increased, a higher current
will flow; therefore, a power supply with an adequate current capability must be used.
(3) When designing printing lines and bit images, take the printing ratio and print duty into
consideration. Print quality may be poor if the printing ratio (energizing pulses/dot line) or
print duty is high.
(4) Average energizing pulse width is defined as 64 of 192 dots/dot line that are energized.
WARNING: Beware not to invert the polarity of power supply. This may
irremediably damage the printer. Ensure that the voltage is the orre t
one.
IMPORTANT NOTE ABOUT POWER SUPPLY:
The required power supply depends on the ontent printed on the ti ket. A 150W power
supply overs all adverse possibilities (printing ratio of 100% bla k at any temperature).
However, if the print ratio is not over 60%, a 60W power supply an be used. In any ase, power
supply must satisfy the peaks urrent that me hanism requires, whi h are determined by the
following formula:

•U B specification U B 2.0 (480Mbits/s full speed)
•Transfer type Bulk
•Maximum receive/transmit endpoint size 64 bytes
•Current consumption from U B bus 2mA max.
User has to use a standard “B” series U B connector.
4.5 - PRESENTER AND LIGHT INDICATOR
Once the ticket has been printed and cut, the K 55 will automatically present it.
The K 55 has several presentation modes which are configured by the single command DC3 P n.
As for the amount of the ticket initially shown, the K 55 can be programmed as short or long. In short
mode, only the first 3 cm (approx.) of the ticket are shown. In the long mode shows the whole ticket less
the last 60 mm (approx.).
FENIX recommend using the short mode for tickets shorter than 18 cm, and the long mode for ticket
longer than 18 cm.
If the ticket is not picked up within the collection time interval (DC3 T n command), before it is collected,
the user can be given a second chance to pick it up by the 2nd Warning option: extracts 30mm more of
ticket (only in short mode) and reset the collection time one again.
With regard to the collection mode (if in any case the ticket has not been picked up), the K 55 can be
programmed so that the ticket is collected inward, into a box set by the developer, or the ticket is ejected
outward (supposedly, falls to the ground).
o that the whole presentation process is visibly more effective, K 55 has a light indicator integrated in
the presenter nozzle to be able to visually warning the user to pick up the ticket,
Using the DC3 L n ton toff command, color (GREEN, RED or ORANGE) and duty cycle can be
determined.
Fig.4.8. K 55 light indicator.
In the 2nd Warning phase of presentation light indicator can be controlled by the command DC3 D n ton
toff, similar to the previous one: color (GREEN, RED or ORANGE) and duty cycle can be determined.

5.1 - PAPER LOADING
There are mainly two ways of loading paper: automatic and manual. In any case, before starting
the paper load sequence, please make sure the paper roll has been placed in the right way.
5.1.1 - Automati paper loading
1. Make sure the K 55 is power supplied.
2. Remove any rest of paper if there is any.
3. Make sure that the platen is closed.
4. Make sure the paper end is cut in a straight way.
5. Thread the paper roll with the right orientation as shown in the next figure. The thermal paper
has only one printing side (thermal side). If there are doubt about which one is the printing side,
just scratch the paper and the thermal side will show up the track on.
6. Once the printer has detected the paper, it will automatically start the paper load sequence
which consist of feeding few millimeters of paper at a very low speed.
Note: running at low speed, the motor will be noisier.
5.1.2 - Manual paper loading
1. Open the printing head by pulling the lever and remove the paper (if there is any). Keep the
printing head open.
2. Place the paper roll in the right direction.
3. Put the paper end in the mechanism inlet. Push the paper in until it reaches the mechanism
outlet.
4. Close the printer head.
5.2 - OPEN THE PRESENTER UNIT
In order to access the print head for cleaning, or to unlock the cutter or remove some paper rest, the
presenter module must be opened. First, lift the indicated lever, and then, move the presenter module
downwards.

- The paper roll end sensor detects a paper end.
- When the door is open.
- When another non-recoverable error is present.
•SELF-TEST MODE: If pressed on start-up with the door closed, it activates this mode.
•HEXADECIMAL MODE: In order to activate it, if the button is still pressed when the full elf-
test has been printed, the printer will prompt the user to hold the button to enter this mode. If
we do not hold the button in the next 3 seconds (meaning NO), the printer will exit to normal
operation.

5.5 - SPECIAL PRINTING MODES
Besides the normal printing mode in which all the received data are printed according to the
settings or conditions fixed by the commands, the K 55 printer allows two special working modes: self-
test mode and the hexadecimal mode.
5.5.1 - Self-test mode
The printer provides the self-
test mode with two different
functionality: showing information
of the settings of that particular
printer model and verifying the
printing.
To enter the self-test mode,
the printer must be powered on
while keeping pressing the button.
The K 55 will start printing a
report, which allows checking the
features of this particular model,
like the firmware current version,
control functions of the
communications protocol, and so
on.
Once this printing has been
finished, if the button is kept
pressed; the printer will start
printing continuously and
repetitively a character pattern until
it finally concludes the self-test by
printing ‘* * completed * *’. This
second option of the self-test mode
has the goal of validating the
printing speed and quality.
At the end of the self-test
page there are few lines showing
the four different maintenance
counts:
1- Times that the printer has been
switched on.
2- Time (in half hours) that the
printer has been powered on.
3- Meters of paper printed.

5.5.2 - Hexade imal dump mode
To enter the hexadecimal mode, proceed in the same way as in the continuous self-test, but keeping
pressing the button until printing "Enter in hexadecimal mode?...".
Then continue with the button pressing for four seconds until
the text "~~~ HEXADECIMA MODE ~~~" has been printed.
This mode can be very helpful for the application developer
during the setup test time, as it allows detecting possible errors
(like out of range parameters, non valid command sequences,
errors in the communication channel, etc.), comparing what it has
theoretically been sent to the printer to what it is really being received.
Turn off the printer to quit the hexadecimal mode.
NOTE :
(1) For any received characters under 20h, the A CII
‘.’ will not be printed.
(2) During the hexadecimal dump mode, the DEL EOT
command does not work.
(3) It must be taken into account that if the number of
bytes is less than the minimum amount required to
print one line (9 bytes), the printer will not print. It is
recommended to complete the hexadecimal dump
by sending at least 9 bytes (for example 00h).
(4) It is also possible to enter the hexadecimal mode
through the GS (A command.
Fig.5.5. HEXADECIMAL DUMP mode example.
5.6 - BLACK MARK SENSOR
The K 55 interface has a specific sensor for optical (black) mark detection.
In order to be able of using this feature, the optical mark sensor must be enabled by programming
command ( ee command DC3 ESC FS GS).
The command that sets black mark offsets (GS ( G) require two parameters that must be
measured physically on the ticket: ticket length which is the distance between two consecutive cutting
lines, and distance from black mark to next cutting line. This parameters will be saved into non-volatile
memory.
This command takes into account the distance from the black mark sensor and the cutter blade
which is fixed in a particular assembly. For this reason, this distance must be kept if a different
implementation is taken.

KS55 SERIES OPERATION MANUAL
Fig.5.6. Black mark programming parameters.
When the black mark photo-sensor is enabled, the behaviour of the printer will change in the
following way:
–When pressing the paper feed button the printer will feed paper to the next cutting line
according to the ticket length parameter set with the GS ( G command ( ee SECTION –
CONTROL COMMANDS) and then it will cut the paper.
–When sending any cut command to the printer will do the same as above.
–When sending a GS FF command to the printer it will feed paper to the next cutting line.
–If the printer detects that paper has been fed for a distance larger that the ticket length without
having cut the paper, it will pop a black mark error.
–The first ticket should be discarded since the printer cannot estimate the distance to the next
cutting line until it has detect at least one black mark.
5.6.1 - Size and spe ifi ation of bla k mark
The position of the black marks are marked on one of the following: on the right or left edge of the
face of the paper, or on the right or left edge of the back of the paper. The standard position of the
bla k mark is on the right side on the ba k of the paper (STD).
