Principles of aiki na Laser printer

Kila, yana da wuya a kwatanta wani mutum a cikin rãyuwar jama'a, sun taba jin kwakwalwa da kuma peripherals domin su Don kwanan wata, wadannan na'urori sun zama kusan ba makawa a cikin rayuwar yau da masu amfani. Daya daga cikin karin mambobin for sauri da kuma sauki aiki ne firintocinku. Matsayin mai mulkin, a irin wannan dabara za a iya samu a kusan kowane ofishin, amma ga m amfani na da saye shi ne da yawa rarer. Duk da haka, mutane da yawa sani game da wanzuwar wadannan na'urori, amma ba kowa da kowa fahimci ka'idojin aiki na firintar.

Akwai biyu main iri firintocinku - inkjet da kuma Laser. Principles of aiki na Laser printer, ba shakka, bai son manufa na aiki da printer inkjet, kamar yadda biyu da daban-daban zane. Don kwanan wata, masu amfani da fi son a zabi wani model tare da Laser bugu, jayayya da cewa mafi girma quality. Hakika, wadannan model da wani yafi hakan kudin, amma idan akwai wani m bukatar samar da high quality-images, farashin pales cikin insignificance.

Saboda haka, abin da su ne ka'idodin da Laser printer? Da farko, ya kamata a lura da cewa su ne bisa zane fasali na na'urar. Fitar da wani so image a kan electrophotographic fasahar faruwa. Shi ya ta'allaka ne da cewa kowane batu a kan takardar da aka located a takamaiman wuri a kan shafin ta hanyar canza electron cajin a kan musamman fim. Yana yawanci kunshi wani semiconductor iya canza lantarki watsin da radiation. A wannan fasaha da aka saba amfani a copiers.

Abin da ka'idodinta a Laser printer, kome zai faru ba tare da wani juyawa drum, wanda shi ne babban tsarin kashi na dukan na'ura, shi ne da taimakon da canja wurin daukan sanya hoton a kan takardar da takarda. Yana da wani Silinda na karfe wanda aka rufe da sosai musamman semiconductor fim. Da farko, wannan drum surface da aka tuhuma da tabbatacce ko korau ions.

Next, ta amfani da Laser haske katako generated superfine wanda motsa drum, nuna daga mahara ruwan tabarau da madubai. Suna sauka a farfajiya na drum discharges haske tabo a wurin contact. A Laser yawanci microcontroller controls a kuma kashe kamar yadda ya cancanta. Yawancin lokaci, image samuwar kan drum faruwa layi da line. A karshen jawo hotuna a kan wannan layin, musamman engine, ta kuma yi kira a stepper, dan kadan cranks drum to suna da wata damar kara da Laser. Saboda haka, akwai a kan Silinda surface image kunshi cajin maki. Wadannan maki ana alternated da caji, located in wurare inda akwai ya kamata ba image.

A mataki na gaba na Laser printer aiki ka'idojin unsa kai tsaye aikace-aikace na image a kan takarda sheet. Kafin wannan wurare a caje surface na drum sandunansu ga Toner da ciwon da m cajin. A wannan yanayin, da drum rotates sannu a hankali zuwa ga Paint ne a ko'ina rarraba. Ci gaba da juya, da Silinda na Toner ajiye a kan shi a lamba tare da takarda surface, inda tawada da aka canjawa wuri uwa da takardar.

Next, takardar dole wuce tsakanin biyu shafts. Kullum, da babba shaft na da babban zazzabi, da kuma ƙananan shaft presses da babba takardar. Saboda haka, tawada barbashi ne mai tsanani da kuma gyarawa a kan takarda surface. A karshe drum ake tsabtace na saura Toner musamman na'urar, sa'an nan dukan na bãyan tẽkun cajin ne amfani sake.
