This kit platen roller with gear is suitable for Zebra QLN320 ZQ620 portable thermal barcode label mobile printer and highly compatible with it. Part number: P1031365-022. Please check the device model carefully before purchasing. This platen roller is made of high-quality rubber material, which is aging-resistant and corrosion-resistant. Thicker rubber can withstand the friction of long-term operation, giving the roller a longer service life. It can provide smooth and even pressure during the printing process to ensure the clarity of barcode labels. The gear speed is high, the beat is small, and there is no noise, making the platen roller run smoothly. It can ensure that the printer operates at high speed, thereby improving printing efficiency. The snap on connections make installation simple and convenient, reducing downtime and improving work efficiency. The platen roller exerts enough pressure to help the label paper stay flat during the print process without offset and paper jam problems, thereby ensuring the quality and stability of the printout. It has strong pressure resistance and good flame retardancy. It will not fall off after long-term use. We conduct multiple strict quality inspections and perfect packaging before shipping.
