TK14 OPERATION MANUAL
13/65
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.

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]
