Manje, abantu abaningi bafuna ukwazi ukuthi yimuphi umphumela ongcono phakathi kwesikena kanyeikhamera yedokhumentiNgaphambi kokuphendula lo mbuzo, ake sixoxe ngemisebenzi eyinhloko yalezi zibili. I-Scanner iyithuluzi elihlanganisiwe le-optoelectronic elavela ngawo-1980, futhi umsebenzi walo oyinhloko ukwenza imibhalo yamaphepha ibe nge-electron. Ekuqaleni kokuzalwa kwekhamera yamadokhumenti, umsebenzi oyinhloko ukwenza imibhalo yamaphepha ibe nge-electron. Umehluko kuphela phakathi kwama-scanner umgomo wokusebenza. La madivayisi amabili abhekana nezidingo ezifanayo, ngakho abathengi abaningi bafuna ukuqhathanisa nokubona ukuthi iyiphi idivayisi enomphumela ongcono. Umehluko omkhulu phakathi kwekhamera ephezulu nezinhlobo ezahlukene zama-scanner awusiwo umphumela kakhulu, njengoba isimo sohlelo lokusebenza sihlukile.
Izici eziyinhloko ze-ikhamera yedokhumentiyilezi: amadokhumenti askeniwe awadingi iphepha, akukho mfucuza yephepha, afanele ihhovisi elingenaphepha. Isivinini sokuskena sethuluzi lokushaya okuphezulu siyashesha, kuyilapho isikena sendabuko siyinkimbinkimbi kakhulu uma uskena idokhumenti, udinga ukuphakamisa isivalo ukuze uphendule ikhasi, futhi ithuluzi lokushaya okuphezulu lingaskena ikhasi ngqo. Isikena sendabuko siyinkimbinkimbi kakhulu uma uskena amadokhumenti. Isikena esiyisicaba siwumthombo wokukhanya ovaliwe, ongathinteki ukukhanya okunamandla, ukuskena isithombe ngeke kushintshe, ngokuyisisekelo singafinyelela usayizi ongu-1:1, ukubuyiselwa kombala ophezulu, isithombe esicacile. Kufanelekela ukuskena imidwebo yombala, izithombe, nezithombe.
Umsebenzi oyinhloko wesikena ukuskena, kodwa ukuze nje siskene ukuze siqhathaniswe, isikena singcono kunethuluzi elisebenzisa i-high shot, isixazululo se-optical sesikena singafinyelela kalula ku-600dpi futhi isixazululo siphezulu kakhulu, sifanelekile ezinhlelweni zokuskena ezinembe kakhulu. Isetshenziselwa ukwenza idatha eyinkimbinkimbi ibe yedijithali kanye nokuqashelwa kombhalo we-OCR,ikhamera yedokhumentiisebenza kahle kakhulu kuneskena, kodwa uma udinga nje umphumela wokuskena onembile kakhulu, iskena singcono.
