barashada weyn ee si toos ah
Rollarka ah ee PCR (Primary Charge Roller) waxaa ka mid ah ee qofka loo sameyn karaa oo ku jirin laser printers iyo copiers, oo ah ee ugu dambeyn karo waxbarashada weyn ee carruurta photosensitive drum. Sidoo kale, wuxuu ugu dhexdhsanayo proseska ah ee la socoto toner particles markii uu lagu printayso. Wuxuuna siiyey meelaha xiriirka ah ee ku saabsan engineering, oo ku yaal rollarka ah ee conductive layer ee si carruurta ah ee ku yimid charge distribution carruurka ah ee drum surface. Carruurka outer layerna ayaa ku jirin rubber compounds ee laf ah ee ku yimid electrical resistance properties over extended periods. Rollarka PCRsna wuxuu ka soo jeedo high voltage AC bias oo ka dib DC voltage, oo lacagta electrical field ah ee la heliyo charging performance. Waxaa ku jiraan components ee ay ku sameyn doono oo ah ee ugu dambeyn karo temperature iyo humidity conditions, oo ah ee ugu dhexdhsanayo print quality haddii awood ah environmental factors. Wholesalen wuxuu ku yimid PCRs ee ay ku samayn doonaa business waxa ay ugu yarannaya printer maintenance programs ee ah ee cost-effective, oo ah ee ugu dhexdhsanayo print quality. PCRs modern ayaa ku jirin materials advanced ee ku resistan wear iyo degradation, oo ay ku yaal lifespan operation ee ay ku noqon doonaa replacement frequency. Rollarka ah ayaa compatible ee ka mid ah ee printer models iyo brands, oo ay ku yidhi inaan ugu yaranaan service providers iyo maintenance technicians. Processka ah ee precision manufacturing wuxuu ka yimid in aan ballanqaado dimensional iyo electrical specifications, oo ah ee ugu dhexdhsanayo reliable performance in professional printing environments.
