rollarka Xiriirka Kuwaas
Roller lacagta badbaad (PCR) waxaa laga heli karaa qof kamid ah oo ka mid ah inta laser printers iyo photocopiers, oo ku jira responsibility carruurka lacagta photosensitive drum. Carruurka lacagta electrostatic waxaa ugu dhexeeya carruurtida toner ee ku saabsanayo inta badbaado process. PCR waa consists of lacag conductive oo ku sameeyay compounds conductive rubber aanuun ah, engineering carruurka electrical properties carruurka across sharciga ah ee environmental conditions. Operating through direct contact with drumka photosensitive, PCR waa lacagta lacagta lacagta lacagta -600 to -900 volts. PCRs modern oo ahaatan materials aanuun ah iyo surface treatments to prevent contamination and ensure long-term reliability. Lacag distribution lacagta lacagta created by PCR waa lacagta lacagta print quality, making it crucial for achieving sharp, clear images and text. PCRs waa designed to operate efficiently across different printing speeds and environmental conditions, maintaining stable charging characteristics throughout their operational lifetime. Technology waa evolved to include self-cleaning mechanisms and wear-resistant coatings, significantly extending the component's service life and reducing maintenance requirements.
