Rs-232 Serial Interface - Fenix 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.
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.

4.3.2 - Change between online and offline mode
The printer is in offline mode:
1) When powering up or resetting the printer, until the printer is ready to receive data.
2) When the door is opened.
3) After pressing the button while the paper advances.
4) When 'out of paper' causes the printer to stop printing.
5) When the power supply has a temporal abnormal voltage change.
6) When an error has occurred.
WARNING: Beware not to invert the polarity of power supply. This may
irremediably damage the printer. Ensure that the voltage is the correct
one.
