Isinyathelo sokuqala sokuxuba ukulawula okuqukethwe kwesithako ngasinye kanye nokushisa kokubhaka, ukuze ubulukhuni nezithako nezithako kungazinza. Ngemuva kokuxuba, ngoba i-colloid isenokungcola futhi ayifani, kufanele ihlungwe. Ngaphezu kokuqinisekisa ukuthi i-colloid ayinalo ukungcola, isihlungi kufanele futhi siqinisekise ukuthi i-roller roller ingagcizelelwa ngokufana ngenkathi isebenza. Isinyathelo sokwenza ama-Rubber roller nokuhlunga kubaluleke kakhulu emishini yokuphrinta eshesha kakhulu, ukuze ivikele ukwanda noma ukukhishwa okubangelwa yizizathu ezihlukile.
Lapho-ke i-roller yenjoloba yezimboni iyafudumala, inqephuke futhi i-Vulcan ithuthukiswe ukuzenzisa ipulasitiki, ukuze irabha linciphe ngesikhathi sokusetshenziswa, i-shrinkage ingancishiswa ibe yincane. Inqubo yokulapha ingayenza ithambe futhi iqine ngaphandle kokulahlekelwa ukuthamba kwayo, ekugcineni ingadlulisela ku-ink.
Okokugcina ukugaya nokupholizwa. Ungadingi lokushisa njalo kwalezi zinyathelo ezimbili. Ngaphandle kwalokho, izinga lokushisa liphansi kakhulu, kulula ukuba brittle ndawo, futhi izinga lokushisa liphezulu kakhulu. Ingaphezulu le-roller yenjoloba yezimboni ithambekele kwi-carbonization, futhi into ye-peiling yenzeka ngesikhathi sokuphrinta, esizokwenza ikhwalithi ye-roller yerabha iyehlile, ngaphandle kwezimpawu zayo ezinhle, futhi ayikwazi ukudlulisa i-ink kahle. , Okuholela ekungcoleni. Lezi zinyathelo ezimbili zokugcina ziyisihluthulelo sokuthola ikhwalithi ye-roller yerabha. Yize ingaphezulu le-roller yenjoloba yezimboni libukeka libushelelezi, kusekhona ukungahambi kahle okuncane okuncane ebusweni. Ukugaya nokupholisa ukwenza i-roller roller eqondile ngokwengeziwe ngosayizi, indawo ebushelelezi, ukusebenza okungcono kokudluliselwa kwe-ink, kanye nekhwalithi ephezulu yokuphrinta
