CLEANING PROCEDURE AND PRECAUTIONS
•
TK14 OPERATION MANUAL
In order to clean the thermal print head, proceed as indicated by the following steps:
1. Unplug the power supply cable and remove the 4 screws (2 in each side) holding the thermal print
mechanism. Open the printer cover. Wet a cotton sponge in alcohol (ethanol, methanol or IPA),
and use it in order to clean the thermal elements of the print head and to remove the possible
accumulation of paper particles found on the cover, roller and nearby surfaces.
2. Wait for alcohol to evaporate before inserting the paper roll and closing the cover.
FENIX recommends cleaning the thermal print head periodically (each 2 or 3 months) in order to keep
the print quality.
NOTES:
!
The print head could 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 for the cleaning of the print head, as they
could scratch it.

2 – INSTALLATION
2.1- TK14 INSTALLATION CONSIDERATIONS
There are some general considerations to take into account when installing the TK14 printer.
A wrong installation can cause many serious problems 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.
This printer is thought to be fixed in a bigger case or structure, or another kind of appropriate chassis.
The basic points that a correct installation must follow are:
•
Allow enough space and
accessibility to reach the
maintenance procedure points
in case it is needed.
Take notice that all user
accessible parts are in the
left and rear side of the
printer, like the next picture shows:

comunication

Led and buttons

•
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.

11/65
FENIX IMVICO
TK14 OPERATION MANUAL
For these reasons, FENIX suggests the following systems as solutions to a correct installation:
The printer must be set quite near the front side of the user’s chassis.
Special care in the design of the part which goes from the printer outlet to the paper guide (paper jams
can occur due to an inappropriate design).
As the printer is placed very near the user’s chassis, some system must be implemented in order to move
the printer when accessing the printing head (i.e. giving the fixing holes of the chassis an oval shape to
allow the printer moving forward and backward).

Depending on the construction materials, care must be taken with static electricity; otherwise tickets may
get stuck in the paper guide and never reach the receptacle.

2.2- POWER SUPPLY
+12V to +24V
The TK14 is powered by an external power supply
by means of a female polarized connector of 4 pins
that includes a security anchor. The power supply
voltage must be verified before making the connection
between the supply and the printer.
The power supply male connector must be a
JST

(housing)
(contact), or an equivalent model.
Fig. 2.4-
GND
TK14 power supply connector.
NOTES:
(1) If the number of dots that are energized at the same time is increased, a higher current will flow;
therefore, the user should use a power supply with an adequate current capacity.
(2) When designing lines and bit images, take the printing ratio and print duty into consideration.
(3) Print quality may be poor if the printing ratio (energizing pulses/dot line) or print duty is high.
(3) 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. Use the 4 terminals (4 wires) with 1 mm² minimum section everyone.
IMPORTANT NOTE ABOUT POWER SUPPLY:
The necessary supply of power depends on the content to print on the ticket. A 60W power supply
covers all adverse possibility (printing ratio of 100% black at any temperature). However, if the
print ratio is not over 60%, a 40W power supply can be used. Any way, power supply must meet
the peaks current that mechanism requires, which are determined by the following formula:
Ipeak = [(number of printing dots) x 8,3] / 176 [A]
= 3,9A
= 0,38A
