13. uctor until it reaches its set temperature and then it becomes a resistor A thermistor is basically a coated semiconductor designed to switch from a conductor to a resistor at an established temperature When a current is applied to the thermistor it initially uses a large amount of electricity and heats up very quickly until it reaches its maximum set temperature At this point it should not use any more electricity However air that is passed through the holes in the thermistor causes it to cool This activates the thermistor to start using more power again so that can get back to its settemperature The thermistor is constantly regenerating itself to stay ata constant temperature This process is called autostabilization Thermistors are also the key element that makes the Tempest dryer safe Because the set temperature of the thermistor is lower than the flash point of paper you can place even the most easily burned substrate such as tissue paper on top of the thermistor element without causing a fire The tissue won t even char let alone ignite If you were to do the same with an IR element a fire could start in a matter of seconds This is particularly important if a jam occurs in the delivery The objective of any drying system is to raise the pile temperature to accelerate the drying of the ink However heating the paper too much can aggravate problems such as blocking setoff mottle loss of gloss and loss of halftone definiti
