Ukudambisairola yerabhaluhlobo lweirabhai-roller esetyenziswa rhoqo kwiimashini zokuprinta ukunceda ukulawula ukuhamba kwe-inki ephepheni. Ezi roller zihlala zenziwe ngokusonga umaleko werabha ekhethekileyo ujikeleze umongo wesinyithi uze emva koko uphathe umphezulu werabha ngeekhemikhali ezahlukeneyo ukuze kufezekiswe iimpawu ezithile zokufunxa. Injongo ye-roller yokufunxa kukuqinisekisa ukuba i-inki inamathela ngokufanelekileyo ephepheni kwaye ayitshisi okanye ichithe. I-roller ifezekisa oku ngokufaka ifilimu encinci yamanzi kwipleyiti ngaphambi kokuba i-inki isetyenziswe, nto leyo enceda ukuthintela i-inki engaphezulu ukuba ingadluliselwa ephepheni. Ukufunxaiirola zerabhaziyinxalenye ebalulekileyo yemisebenzi yokushicilela esemgangathweni ophezulu kwaye zibalulekile ekuveliseni imifanekiso ebukhali necacileyo kwiindidi ezahlukeneyo zezinto.
Kwelinye icala, iirola zerabha zelaphu zisetyenziswa kwiinkqubo zokwenza ilaphu, ezinje ngokusonta, ukuluka, kunye nokuprinta. Zihlala zenziwe ngezinto zerabha ezenziweyo okanye zendalo, kwaye zenzelwe ukubamba nokutsala imicu yelaphu okanye amalaphu njengoko edlula kumatshini.
Nangona ezi ntlobo zimbini zeerola zerabha zinokuba neempawu ezifanayo, usetyenziso lwazo kunye noyilo lwazo zahlukile kakhulu. Iirola zerabha ezithambileyo zenzelwe ngokukodwa ukuprinta ngelixa iirola zerabha zelaphu zenzelwe ngokukodwa ukwenziwa kwelaphu.
