This manual describes the commands relating to the TCP300II series printers.
• The volatile memory writing life is approximately one million times. The expect
ed life will be reached by frequent use, which can cause problems in the operation
of the printer. Therefore, only use the model set command (91h) and the cleanin
g yes/no command (5Bh) when starting up the system.
Note that the parameters that can be set by the model setting command (91h), des
cribe the font size and character spacing with the escape sequence in the print dat
a setting command (41h).
• The print head and erase head are hot. To prevent a dangerous situation, do not
carelessly open the transport path.
• A warning buzzer is installed to ring when the cover is opened. It is possible to send and
receive commands, and to process cards in this state, but to prevent a dangerous situation,
close the cover quickly.
• The buzzer will ring and the LED will flash when the transport path is opened. In this state,
commands cannot be received and cards cannot be processed.
• Closing the transport path after opening it will reset the device. Always reset the
magnetic data and print data because the memory expanded on the memory is destroyed.
• Magnetic reading and writing can experience errors by damaged magnetic data caused
by dirty magnetic cards and external magnetic fields. Carefully handle those errors.
Particularly, you should develop a system for recovering erroneous cards when writing errors
occur.
• Printing times can vary depending on the ambient temperature and temperature of the
thermal head. In particularly low temperature locations, processing of cards may take more
time than usual, but this is not a system failure. Rewriting to magnetic cards will be repeated
several times (when the device is set to rewrite several times) when they are dirty from
repeated magnetic reading and writing, or if magnetic data is damaged by an external
magnetic field. Therefore, the timeout setting to the response after sending a command
should be set to a value higher than the one recommended.
• Turn off the power before switching the interface cartridge or changing settings.
• To maintain print quality and magnetic reading and writing performance, clean the device
once a day. If possible, consider such a warning system to operate when starting up the
device every day.
• Dirt adhering to the magnetic card will cause the magnetic head and transport rollers to wear
out. Avoid using dirty cards.
• Magnetic reading and writing performance will drop if the magnetic head and magnetic card
cannot be brought close together. Do not place adhesive tape on or bend magnetic
cards.
• When the cleaning lamp flashes, clean the device. (This is when the cleaning warning
setting is enabled.)
