Features 1) Using a special compact partial glaze and new heating element structure, achieves high-speed printing at 150 mm/s. 2) The use of the highly-durable conductive protective film has improved countermeasures against static electricity. 3) The VH and GND sections of the power circuitry have been strengthened so that heavier current can be applied. 4) One rank resistance value of 800Ω ± 3% eliminates the inconvenience of rank selection. 5) The required driving voltage of 3.15 to 5.25V allows wide range of power supply voltage setting. This also allows multiple choice of electronic components for printers.
