Mafotokopi munhu wese aona zvakawanda, tumira magwaro anoda kukopwa kubutiro, dzvanya bhatani, mwenje unopenya, uye gwaro rinokopwa.

1. Maererano nemagetsi emagetsi e toner, inogona kugoverwa kuva: yakanaka yemagetsi poda uye yakashata yemagetsi poda.

2, zvinoenderana neiyo magineti ye toner inogona kukamurwa kuita: magineti poda uye isiri-magnetic poda.

3, maererano nekugadzirwa kwe toner yakakamurwa kuva: hupfu hwemuviri uye kemikari poda.

Chinhu chikuru che toner (inozivikanwawo se toner) haisi kabhoni, asi yakawanda yacho inoumbwa neresin uye carbon black, charge agent, magnetic powder nezvimwe zvakadaro. Mukuita basa rekukopa, ndiyo toner inonyunguduka mufiibha yepepa panguva yekudziya kwepamusoro, uye yakanyatso kudzvora fiber yepepa, panguva ino, mamorekuru eokisijeni ari mumhepo mukati memukopi anova maatomu matatu eokisijeni nekuda kweionization. , iro rinova gasi rine hwema hunonhuwa, inova iyo munhu wese anodana 'ozone'. Iri gasi rine bhenefiti imwe chete, ndiko kuti, kudzivirira pasi uye kuderedza kukuvadza kwemwaranzi yezuva. Ozone haina mhedzisiro yakanaka pamuviri wemunhu pachayo, inokonzeresa kutsamwiswa kumunhu mucosa, nyore kuwedzera chiitiko cheasthma kana mhino allergies, uye kunyangwe dzungu, kurutsa uye zvimwe zviitiko.

Izvo zvakare kubva ku1980s zvichienda mberi, kuitira kubvisa ozone uye kuderedza kutyisidzira kwemoto, vagadziri vefotokopi vanoramba vachishandisa nzira dzakasiyana siyana kuedza toner iyo isingade yakakwira-voltage magetsi uye kunyungudika kwakanyanya, izvo zvakakonzera zvakawanda uye. mamwe marudzi e toner, uye kunyange akasiyana maratidziro emhando yephotocopier anogona kushandisa akasiyana toner. Izvo chaizvo nekuti toner yakasiyana, saka mhando dzakasiyana dze toner dzinowanzoratidza kuchinjika kweiyo modhi, iyo mhando pabhokisi. Dzimwe nguva toner isina kunaka inoshandiswa, uye photocopier pachayo "ichadana mapurisa" uye inoramba kutanga.
