1. Umkopishi usebenzisa izici ezingaba khona zomqhubi we-optical ukushaja umqhubi we-optical ngaphandle kokukhanya, ukuze indawo engaphezulu ishajwe ngokufanayo, bese ngomgomo wokuthwebula izithombe, isithombe sangempela sithwetshulwa ku-conductor optical.

2. Ingxenye yesithombe ayikhanyisiwe, ngakho ubuso bomqhubi wokukhanya buseneshaji, kuyilapho indawo engenasithombe ikhanyisiwe, ngakho-ke ukushaja okungaphezulu kwekhondatha yokukhanya kudlula emhlabathini we-substrate, ukuze ukushaja ebusweni kuyanyamalala, ngaleyo ndlela kwakheka isithombe esifihlekile se-electrostatic.

3. Ngomgomo we-electrostatic, i-toner ene-polarity ehlukile isetshenziswa ukuguqula isithombe esifihlekile se-electrostatic esingaphezulu kwekhondatha yokubona sibe isithombe se-toner ebusweni bekhondatha yokubona. Ngomgomo we-electrostatic, isithombe se-toner esingaphezulu komqhubi we-optical sidluliselwa ebusweni bephepha lokukopisha ukuze kuqedelwe inqubo eyisisekelo yokukopisha.
