The PTC thermistor is used to quickly bring the printhead up to operating temperature, increasing your first time print cycle, and conserving energy.
Our thermal printhead incorporates the use of positive temperature coefficient (PTC) and negative temperature coefficient(NTC) thermistors for regulating temperature in the printhead. Our thermal print head uses a hard black epoxy and silicon glass clear coating to protect the gold wire bonds and sensitive electronic circuitry against moisture and harsh environments. We believe the gold wire bond provides for greater signal integrity and a longer life of the printhead. Our thermal printhead will use Gold wire bond between the printed circuit board and ceramic substrate. A 15% change in the value of resistance results in a printhead unable to function and print the required dot density. As a thermal printhead wears the value of resistance changes. The thick film technology allows for a reduction in resistance versus pressure contact technology. Thick Film printheads use gold, insulating and resistive pastes which are screen printed onto a ceramic substrate. Our Thermal Print head uses Thick film technology. The Diamond like coating will protect the printhead when used in bar coding, ticket printing, thermal printing, printing against ribbons, and printing using other abrasive media. Our Diamond like coating provides a surface hardness equivalent to Rockwell 85 to 90. Our Printhead is built using a protective diamond like carbon (DLC) coating and is specifically designed for Zebra Part Number G79057. Direct thermal or thermal transfer printhead. Resistor line location (edge, near edge, etc.) Allows you to print at the edge of your media. Print speed up to 12 inches (300mm) per second. Our printhead duty cycle provides you with clarity, print accuracy, and accurate dot reproduction. Our printhead is built for a 100% dot duty cycle. The resistance in our thermal printhead is consistent up to 330,000 inches. This is not a rebuilt and not a re-manufactured Printhead - BRAND New and Made in the USA. This is a brand-new Zebra OEM Compatible Printhead. 
Our New Zebra compatible thermal printhead is available for shipment worldwide.
Our OEM Compatible Printhead works in the following Zebra printer models: Z4M, Z4000, Z4M+ & Z4M Plus Installation: Temperature Settings may need Adjustments Environmental Protection: Resistive Pastes with Gold Circuitry
