Umshini wokufothokhopha wonke umuntu usebone okuningi, thumela amadokhumenti adinga ukukopishwa kukhava, cindezela inkinobho, ukukhanya kuyaphazima, bese kukopishwa idokhumenti.

1. Ngokusho kwezakhiwo zikagesi ze-toner, zingahlukaniswa zibe: i-powder kagesi enhle kanye ne-powder kagesi engalungile.

2, ngokusho kwezakhiwo kazibuthe ze-toner zingahlukaniswa zibe: impushana kazibuthe kanye ne-non-magnetic powder.

3, ngokusho kwenqubo yokukhiqiza ye-toner ihlukaniswe yaba: impushana ebonakalayo kanye nempushana yamakhemikhali.

Ingxenye eyinhloko ye-toner (eyaziwa nangokuthi i-toner) ayiyona i-carbon, kodwa iningi layo lakhiwe nge-resin ne-carbon black, i-ejenti yokushaja, i-powder magnetic nokunye. Enqubweni yomsebenzi wokukopisha, yi-toner encibilika ku-fiber yephepha ngezinga lokushisa eliphakeme ngokushesha, futhi idonsa ngokuqinile i-fiber yephepha, ngalesi sikhathi, ama-molecule e-oksijini emoyeni ngaphakathi kwe-copier aba ama-athomu amathathu omoya-mpilo ngenxa ye-ionization. , ephenduka igesi enephunga elimnandi, okuyilokho wonke umuntu akubiza ngokuthi 'i-ozone'. Le gesi inenzuzo eyodwa kuphela, okungukuthi, ukuvikela umhlaba nokunciphisa ukulimala kwemisebe yelanga. I-ozone ayinawo umphumela omuhle emzimbeni womuntu ngokwawo, izobangela ukucasuka ku-mucosa yomuntu, kulula ukwandisa izehlakalo ze-asthma noma i-allergies yekhala, ngisho nesiyezi, ukuhlanza nezinye izenzakalo.

Futhi kusukela ngawo-1980 kuya phambili, ukuze kuqedwe i-ozone futhi kuncishiswe usongo lomlilo, abakhiqizi be-photocopier bayaqhubeka nokusebenzisa izindlela ezihlukahlukene zokuzama i-toner engadingi ugesi wamandla aphezulu kanye nokuncibilika kwezinga lokushisa eliphezulu, okuye kwabangela okuningi futhi izinhlobo eziningi ze-toner, kanye nokucaciswa okuhlukile kohlobo lwe-photocopier kungasebenzisa i-toner ehlukile. Kungenxa yokuthi i-toner ihlukile, ngakho-ke izinhlobo ezihlukahlukene ze-toner zizovame ukukhombisa ukujwayela kwemodeli, umkhiqizo osebhokisini. Ngezinye izikhathi i-toner engalungile isetshenziswa, futhi i-photocopier ngokwayo "izobiza amaphoyisa" futhi yenqabe ukuqala.
