TK-41 OPERATION MANUAL
20/88
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 a current
capacity adequate for the corresponding print duty.
•
When designing lines and bit images, take the printing ratio and print duty into
account.
•
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)
•
Average energizing pulse width is defined as 107 of 160 dots per dot line that are
continuously energized.
WARNING : Beware not to invert the polarity of power supply. This may
irremediably damage the printer.
IMPORTANT NOTE ABOUTTK42 POWER SUPPLY:
The necessary power supply depends on content printed in the ticket.
A 150w power supply covers all adversed possibility (printing ratio of 100%
black at any temperature). However, if the print ratio is not over 60%, a 60w
power supply can be used. Any way, 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
