Igubu le-OPC liyinxalenye ebalulekileyo yomshicileli kwaye liphethe i-toner okanye i-inki cartridge esetyenziswa ngumshicileli. Ngethuba lenkqubo yokushicilela, i-toner idluliselwa ngokuthe ngcembe kwiphepha nge-drum ye-OPC ukwenza ukubhala okanye imifanekiso. Igubu le-OPC likwadlala indima ekusasazeni ulwazi lomfanekiso. Xa ikhompyutha ilawula umshicileli ukuba aprinte ngomqhubi wokuprinta, ikhompyutha kufuneka iguqule umbhalo kunye nemifanekiso ukuba iprintwe ibe ziimpawu ezithile ze-elektroniki, ezithunyelwa kwidrum ye-photosensitive ngeprinta kwaye emva koko iguqulelwe kwisicatshulwa esibonakalayo okanye imifanekiso.
