IMPORTANT NOTES IN TK14 THERMAL PRINTER MANAGEMENT

In order to preserve the life of the printer, it is necessary to keep in mind some precautions in the handling of the TK14 printer. Please read carefully the following points in order to make a good use of the printer.

SECURITY PRECAUTONS

•

Before using the printer, read carefully section 2-

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. Making

different connections could permanently damage the printer.

•

Use a power supply voltage 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 TK14 thermal printer with water or any other liquid. If any liquid is spilled inside of the

equipment, unplug the power cable immediately and then contact your technical service.

•

Make sure the printer is on a steady, horizontal, securely fixed surface. If the printer fell down, it could

break or damage.

•

NEVER

use the printer in high humidity or dirty places.

•

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

shock the TK14 printer.

•

NEVER

disassemble or modify the TK14 printer.

•

NEVER

try to repair the TK14 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 with metal 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 your hands the areas around the print head and the motor surface as they become

very hot during and just after printing; wait 15 seconds 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.

•

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 security reasons, unplug the printer if it is not going to be used over a long period of time.

•

Don’ t print continuously (without stopping) for more than 6 minutes.

CLEANING PROCEDURE AND PRECAUTIONS

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.

Fig. a.

Thermal print head cleaning.

RECOMMENDATIONS

•

The plug has to be located near the printer and have to be easily obtainable

•

Before connecting any communication data cable, check the printer is working properly by executing

the self-test.

•

Set the TK14 in a place where the connection cables do not suffer stretching or cross with each other.

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:

Fig. 2.1-

TK14 accessibility

•

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.

FENIX IMVICO

TK14 OPERATION MANUAL

12/65

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).

Fig. 2.2-

Nozzle hole dimension.

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. Be sure to make a good earth connection, performing one of the following schemes:

2.2- POWER SUPPLY

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

VH396-04-H

(housing)

VH396T-010

(contact), or an equivalent model.

Fig. 2.4-

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 us ed. 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]

NOTES: (1)

The ‘n’ prefix used before a signal name means that they are active in ‘0’ logic level. If the host system does not provide any of the signal lines mentioned above, both communication types could fail.

(2)

It is recomm ended to use twisted pair cables (signal/ground), with the return s ides connected to the system signal ground level.

(3)

Do not ignore the nACK and BUSY signals during data transmiss ions. An attempt to transmit data without nACK or BUSY control signals might cause lost data.

(4)

The interface cables should have the minimum required possible length (maximum recommended length: 2 m).
