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 PTD55 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 PTD55 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 continuously (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- Soak 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.
NOTES:
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.
Fig.2.1. Thermal print head cleaning.
2.4 - RECOMMENDATIONS
• The plug has to be located near the printer and has to be easily obtainable.
• Before connecting any communication data cable, check the printer is working properly by
executing the self-test.
• Set the PTD55 in a place where the connection cables do not suffer stretching or cross with
each other.
• IMPORTANT!!! Since the printer demands high current peaks during operation it is advisable to
make the power supply cables the shortest possible.

4 - INSTALLATION
4.1 - INSTALLATION CONSIDERATIONS
The PTD55 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, 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:
• Smooth 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.
• Prevent final user’s from accessing the printer outlet.
• 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
– Paper box location.
– Connectors.
– Led and push-button.
• Fix the PTD55 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. 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
PTD55 can be moved backwards and forwards for easy maintenance.
Fig.4.1. Fixing the PTD55 onto a sliding tray or through fixing slots.

4.2 - PTD55 CONNECTORS
On the PTD55 could be found the following connectors (see APPENDIX HOW TO ORDER):
Fig.4.3. USB or SERIAL RS232 interface connectors.
4.2.1 - Power supply connector
The PTD55 is powered by an external power supply by means of 3-pins connector shown below.
Verify power supply voltage before connecting the printer.
Fig.4.4. Power supply connector J1.
Use a 3-pin DC jack TCS-7960-43-2010 (HOSIDEN) or equivalent. (See APPENDIX – HOW TO
ORDER-ACCESSORIES).

PTD55 SERIES OPERATION MANUAL
NOTES:
(1) The PTD55 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 correct
one.
IMPORTANT NOTE ABOUT POWER SUPPLY:
The required power supply depends on the content printed on the ticket. A 150W power
supply covers all adverse possibilities (printing ratio of 100% black at any temperature).
However, if the print ratio is not over 60%, a 60W power supply can be used. In any case, power
supply must satisfy the peaks current that mechanism requires, which are determined by the
following formula:
Ipeak = [24/657] x number of printing dots
FENIX offers different power supplies as an accessory option (See APPENDIX – HOW TO
ORDER). These power supplies which have been exhaustively tested are available in open frame or
enclosed version.

4.5 - PAPER NEAR-END INPUT CONNECTION
The PTD55 has an optional input which can be used to warn the maintenance operator that the
printer is running out of paper although there is still paper to print few tickets. When the remaining paper
in the box reaches a level that can be considered "near-end", the system can alert the operator to
replace by another box of paper. This can be done by querying the status of the printer (DLE EOT n =4
command).

5 - BASIC OPERATIONS
The PTD55 contains an internal photo-sensor that acts as optical mark detector. In most cases, the
optical mark is a hole (corner cut), whereby the sensor is mechanically located at one end side of the
ticket 54mm. The PTD55 uses the space between two consecutive corners (“black mark”) to identify the
cut positioning.
Fig.5.1. Corner to positioning the cutting.
Because there really is not a standard set (only the width and length: 54x85mm), there may be
numerous types of corners and joints between tickets:
Fig.5.2. Real examples of preformed tickets.
NOTE: FENIX recommended to use tickets with straight cut corners (45º), as large as
possible, as in Figure 5.1.
Some types of preformed tickets, like the following image, may not function properly.
Fig.5.3. Preformed ticket NOT recommended.
15 of 57
PTD55 SERIES OPERATION MANUAL
5.1 - ADJUST ING THE CUTTING POSITION BY COMMAND
3.1- To adjust the distance between the black mark and cutting line, the PTD55 provides the
standard command GS ( G nL nH mL mH, where:
hexadecimal
GS ( G : 1D 28 47 → Command head (Always fixed).
nL nH : A8 02 → Total length of the ticket in dots (Always fixed).
85 mm = (85 x 8) dots = 680 dots
680 decimal = 02A8 hexadecimal
mL mH : 1C 00 → Offset distance in dots between the top of the black mark and the next
cutting line of the ticket in the feed direction (Variable depending on
the preformed).
As it indicated above, the fact that there are different preformed, as well as mechanical tolerances
and mounting, causes the mLmH distance is variable.
An example of trial-error adjustment is shown:
1.- For the preformed shown in the image,
suppose that you start by mLmH = 1C00 value and
the cut has exceeded the desired line (in red).
2.- In a second attempt, decreasing the
value of mLmH = 0200, pruduce the opposite
result. The cut occurs before the desired line.
3.- Therefore, by selecting an intermediate value
mLmH = 0800, the cut is achieved in the right
place.
16 of 57
PTD55 SERIES OPERATION MANUAL
5.2 - CUTTING POSITION SELF-ADJUSTING
The PTD55 has a self-adjusting, whereby the parameter mLmH is estimated practically.
To perform the self-adjusting follow these steps:
1º ) Turn the printer off and the head lever down.
2º ) Keeping the PFEED button pressed, turn the printer on and lift the head lever.
Immediately the PTD55 will issue 4 tickets and will make a cut. From here, each time the PFEED button
is pressed a ticket is issued and cut with the parameters calculated.
If the final result of self-adjusting is not satisfactory, the developer must fit the parameter mLmH by
sending the command GS ( G nL nH mL mH (see above).
NOT E S :
- After sending the GS ( G command (or by self-adjusting), the parameters are stored in non-
volatile memory.
- When pressing the paper feed button the printer will feed paper to the next cutting line according
to the parameters set with the GS ( G command.
- 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.
5.3 - LOADING PAPER
5.3.1 - Automatic paper loading
1. Make sure the PTD55 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.
5.3.2 - 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.

PTD55 SERIES OPERATION MANUAL
5.4 - OPEN CUTTER UNIT
Sometimes the cutter could get jammed if thicker paper is used, the printer mechanism is not
properly closed or other reason. In that case the printer will report a cutter error and may not be possible
to open the printer mechanism to fix it. In order to, manually release the cutter blade the cutter unit
has a wheel that, when turned, will move the cutter blade up or downwards depending.
Fig.5.4. Unlocking the cutter blade.
5.5 - BUTTON FUNCTIONS
Fig.5.5. Button location in USB and SERIAL interfaces.
The on-board button has the following functions:
• PAPER FEEDING: when the printer is powered on pressing the button will feed the paper.
The paper roller will not move under the following conditions:
- 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 Self-
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.
