Precautions For Handling - Star Micronics TUP500 Series Product Specifications Manual

9.4. Precautions for Handling

(1) To prevent static electric damage to the thermal head's heating elements and the IC, handle
the printer only after preparing for anti-static and grounding yourself.
(2) Handle the thermal head carefully because applying mechanical stress or shocks to it
(including wear out by micro-granules), it is possible to damage the PCB surface of the
heating elements.
(3) We cannot guarantee the print quality or the life of the printer if you use any paper type other
than that we recommend. Therefore, always use the paper (thermal paper) recommended.
Particularly, if using paper that has Na+, K+ and Cl-, the thermal head life will be notably
decreased.
[Ex. of Trouble]
(1) Decreased print quality caused by low-sensitivity recording paper
(2) Erroneous wear of the thermal head caused by rough paper surfaces
(3) Sticking of the thermal layer and thermal head and vibration sounds when printing
(4) Missing print caused by low-storage recording paper
(5) Electrolytic corrosion of the thermal head caused by bad quality heat-sensitive layer
(4) Do not allow condensation to form.
If condensation does form, absolutely do no turn ON the power until it has evaporated.
(5) Absolutely never directly touch the thermal head heating elements, the electronic
components
on the control board, or the pins with your hands or a screwdriver.
(6) Avoid leaving the printer without paper.
(7) Be careful not to allow foreign objects to adhere to the recording paper and the platen.
(8) Do not pull on the paper without opening the platen.
(9) When closing the platen from an open state, check that it has been correctly locked by the
locking mechanism before operating the printer.
(10) Printed thermal paper may have an electrostatic charge. The discharged paper may be
attracted to the printer and may not fall.
(11) Absolutely never change the paper width during use. Because the wear-out of the thermal
head, platen and cutter vary according to paper width, there is the possibility of problems
occurring when printing and cutting paper.
(12) Absolutely never forcefully pull on the power cable or cable connected to the interface card.
Particularly, when disconnecting the cables, grip the connector itself to avoid applying
excessive stress to the printer connectors.
(13) Do not cover the paper discharge outlet.
(14) This device employs a motor and switches that have an electrical contact point. Do not use
the device in environments that are volatile because of the presence of silicon gas or other
flammable gases.
(15) This printer has metal plating in some parts. These parts may experience rusting, but that
will not affect the printer's performance.
(16) There are cases of discoloring of the recording paper, degradation of the coloring layer, the
recording paper and platen fusing together or paper curling in the paper feed path, if the
printer is left unused for extended periods.
So, when using the printer after having been unused for extended periods, it is
recommended to install new recording paper because these phenomena can cause
improper printing or poor paper feeds. Also, even if you do not replace the paper with a new
roll, you should discharge the part of the paper remaining for a long time in the paper feed
path before using this printer.
(17) The platen rubber may deform making printing thinner in some places, if the printer is left
unused for extended periods.
(18) Initial print may be thin when using the printer in a cold environment because the thermal
head is cold.
(19) When using the printer in a high temperature environment, the print may run or characters
may be distorted.
(20) Avoid sudden changes of the environment even if the ambient temperature and humidity are
within standard.
(21) Do not store or use the printer in locations that are dusty, oily or exposed to metallic dust.
