Izinga lamadokhumenti akopishwe umkopishi wobunjiniyela alilihle. Yiziphi izizathu ezithinta ikhwalithi yokukopisha? Namuhla, ake umphathi wesondlo we-Putian Da photocopier achaze ulwazi olufanele lwezizathu ezithinta ikhwalithi yomkopishi. Ngethemba ukuthi ukwabelana komhleli kungakunikeza ukuqonda okujulile kokugcinwa komshini wokufothokhopha.

1. Ikhwalithi ephansi yekhophi iyiphutha elivamile labakopishi, elibalela ngaphezu kuka-60% yenani lenani lokuhluleka. Okulandelayo ukuxazulula izinkinga ezithile. Amakhophi amakhophi amnyama wonke. Ngemva kokukopisha, ikhophi iba mnyama ngokuphelele ngaphandle kwesithombe. Imbangela yokwehluleka kanye nendlela yokuqeda: Noma ngabe isibani esivezwayo sonakalisiwe, siphukile, noma unyawo lwesibani aluxhumene kahle nesibambi.

2. Ukwehluleka kwesekethe yokulawula isibani: Uma isifunda sokulawula isibani esivezwayo sihluleka, hlola ukuthi i-voltage ijwayelekile yini. Uma ingekho i-voltage, hlola isifunda esilawula isibani sokuchayeka ezinkingeni, bese ushintsha ibhodi lesifunda uma kunesidingo.

3. Ukwehluleka kwesistimu yokubona: Isistimu yokubona ye-copier ivinjwe izinto zangaphandle, ukuze ukukhanya okukhishwa isibani sokuchayeka kungakwazi ukufinyelela phezulu kwesigubhu se-photosensitive. Susa izinto zangaphandle. Isibuko singcole kakhulu noma silimele, futhi i-engeli yokubonisa iyashintsha. Ukukhanya kuphakeme kakhulu ukuveza isigubhu. Isibuko singahlanzwa noma sishintshwe, futhi i-reflection angle ingashintshwa.

4. Ukwehluleka kwesici sokushaja: Uma isici sokushaja sesibili sinephutha (sisebenza kuphela endleleni yokuphindaphinda ye-NP), hlola ukuthi isiphetho se-electrode yokushaja siphukile yini ngenxa yokuphuma, nokuthi i-electrode ixhunywe kusihlangu sensimbi (lapho izimpawu zokusha), okuholela ekuvuzeni.
