2.2.1- POWER SUPPLY CONNECTOR
Attach power supply cable to the 3-pin micro connector. Verify power supply voltage
before making the connection.
The connector is a female 3-pin HOSIDEN type, which have the following pin-out:

Use a 3-pin DC jack KPP-3P model or equivalent.
The TK51/IF9000 requires one power source: VCC (24V DC) for driving the thermal
head and motor. The power supply must meet the following conditions:
VCC: 24V DC +/- 2,4V (10%)
NOTES
✔
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 capability.
✔
When designing lines and bit images, take the printing ratio and print duty into
consideration.
✔
Print quality may be poor if the printing ratio or print duty is high.
Definitions:
•
Printing ratio: the number of printing dots (energizing pulses)/dot line.
•
Print duty: the number of printing dots (energizing pulses)/ elements/ paper
feed amount (two steps, including non-printing area)
WARNING: Beware not to invert the polarity of power supply. This may
irremediably damage the printer.
IMPORTANT NOTE ABOUT TK51/IF9000 POWER SUPPLY:
The current demand depends on the density of the printout. A 150W power
supply covers all adverse possibility (printing ratio of 100% black at any
temperature). However, if the average print ratio is not over 25%, a 60W power
supply can be used. Anyway, power supply must meet the peaks current that
mechanism requires, which are determined by the following formula:
Ipeak = [24 / 600] x number of printing dots
