Principles of ọrụ nke laser ngwa nbipute

Eleghị anya, ọ bụ ike iche n'echiche na mmadụ na ugbu otu, mgbe nụrụ na kọmputa na peripherals ha Iji ụbọchị, ndị a ngwaọrụ aghọwo ihe fọrọ nke nta oké mkpa ná ndụ nke taa na-eji ọkụ. Otu nke inyeaka òtù maka ngwa na mfe ime ihe ndị na-ebi akwụkwọ. Dị ka a na-achị, a ahụ Usoro nwere ike ịchọta fọrọ nke nta ọ bụla ụlọ ọrụ, ma n'ihi na anụ ụlọ na-erigbu ya nnweta bụ ọtụtụ rarer. Ma, ọtụtụ ndị mmadụ mara banyere ịdị adị nke ndị a ngwaọrụ, ma ọ bụghị onye ọ bụla na-aghọta ụkpụrụ nke ime ihe nke na ngwa nbipute.

E nwere isi ihe abụọ na ụdị nke na-ebi akwụkwọ - inkjet na laser. Principles of ọrụ nke laser na ngwa nbipute, n'ezie, ọ dịghị amasị ụkpụrụ nke ime ihe nke na ngwa nbipute inkjet, dị ka abụọ nwere dị iche iche a haziri. Ka ụbọchị, na-eji ọkụ na-ahọrọ na-ahọrọ a nlereanya na laser obibi, na-arụ ụka na elu mma. N'ezie, ndị a ụdị nwere a nnọọ elu na-eri, ma ọ bụrụ na e a mgbe nile mkpa iji na-emepụta elu-edu oyiyi, na price pales obere.

Ya mere, ihe bụ ụkpụrụ nke a laser ngwa nbipute? Mbụ niile, ọ ga-kwuru na ha na-dabeere na imewe atụmatụ nke ngwaọrụ. Ibi akwụkwọ a chọrọ image na electrophotographic technology emee. Ọ dabeere n'eziokwu na onye ọ bụla mgbe na mpempe akwụkwọ a na-emi odude ke a kpọmkwem ebe na page site na-agbanwe elektrọn ụgwọ na pụrụ iche nkiri. Ọ na-emekarị mejupụtara a okporo ọkụ ike nke na-agbanwe agbanwe eletriki conductivity nke radieshon. Otu technology na-ejikarị na copiers.

Ihe ọ bụla ụkpụrụ nke a laser ebi, ọ dịghị ihe ga mere enweghị a n'usoro n'usoro drum, nke bụ isi bughi mmewere nke dum ngwaọrụ, ọ bụ na-enyemaka nke nyefe-ewe ebe oyiyi na a mpempe akwụkwọ. Ọ bụ a cylinder nke metal nke kpuchie na pụrụ nnọọ iche okporo ọkụ film. Mbụ, a drum n'elu a na ebubo na ebughi ion.

Ọzọ, site na iji a laser ìhè doo eme ọkasị mma nke na-akpali ndị drum, gosipụtara si multiple anya m na enyo. Impinging n'elu nke drum discharges ìhè ntụpọ n'ebe kọntaktị. The laser emekarị microcontroller njikwa na na dị ka ọ dị mkpa. Na-emekarị, image guzobere na drum na-ewe ebe akara site akara. Ná ngwụsị nke na-eru foto na otu akara, a pụrụ iche engine, na-akpọ a stepper, ubé crank nke dị n'ụkwụ drum ka nwere ohere kwalitekwa laser. N'ihi ya, ọ na cylinder n'elu image esịnede ebubo ihe. Isi ihe ndị a na-alternated na pụchara, emi odude ke ebe e kwesịrị image.

Na nzọụkwụ ọzọ nke laser ngwa nbipute ọrụ ụkpụrụ na-agụnye kpọmkwem ngwa nke oyiyi na akwụkwọ mpempe akwụkwọ. Tupu a ebe na ebubo elu nke drum ruo na toner enwe ndị na-abụghị ego. Na nke a, na drum agbagharị nwayọọ nwayọọ na agba na-evenly kesaa. N'ịnọgide na-bugharia, na cylinder nke toner edebe na ya na kọntaktị na akwụkwọ n'elu, adịru ink na-agafere n'elu mpempe akwụkwọ.

Next, akwụkwọ akụkọ ga-agabiga n'etiti abụọ akụ. N'ozuzu, elu okporo nwere a elu okpomọkụ, na ala okporo presses elu mpempe akwụkwọ. N'ihi ya, ink ahụ bụ kpụ ọkụ n'ọnụ na ofu na akwụkwọ n'elu. Ke akpatre drum na-kpochara nke ihe mmapụta toner pụrụ iche na ngwaọrụ, na mgbe ahụ dum ya elu ụgwọ na-etinyere ọzọ.
