Isitembu esizibhalayo siwuhlobo lwesibambi esiqinile esinephedi kayinki eyakhelwe ngaphakathi. Uma sisetshenziswa, uphawu luhlehla ngokuzenzakalelayo futhi lumboze itafula lokuphrinta. Iwuhlobo lwekhwalithi ephezulu kanye ne-high-grade seal, enombhalo ocacile, isakhiwo esizinzile, esiqinile futhi esihlala isikhathi eside, iphedi ye-inki eshintshwayo, futhi ukusebenziseka kwayo nokuqina kwayo kuthandwa ngamabhange, izibhedlela kanye namanye amayunithi.
Isitembu esizibhalayo siphinde sihlukaniswe ngokwesitembu sombhalo, usuku/usuku+umbhalo, inombolo/inombolo+umbhalo. I-self-inking dater esebenzisa impahla ye-ABS, ibhande lenjoloba elingasheleli, yenza uphawu luzinze, lucace kakhudlwana, ukwakheka kwegiya kungalungisa usuku, iminyaka eyi-12 elungisekayo, impilo ende yesevisi.
Ifanele ukusetshenziswa kosuku noma usuku + imboni yombhalo, ukubamba ukhululekile, kulula ukulungisa usuku, uphawu olubushelelezi. Umsebenzi wosuku ungahlangabezana nazo zonke izinhlobo zezidingo zophawu, ungaqoshwa inombolo yenqwaba yomkhiqizo, ukuhlolwa, usuku lwefekthri, usuku lokuphelelwa yisikhathi, igama + usuku, usuku oluphindwe kabili noma usuku oluphindwe kabili + umbhalo ungasetshenziswa kusukela osukwini lokukhiqiza kuze kube usuku lokuphelelwa yisikhathi.
1. Yenziwe ngekhwalithi ephezulu, ekhululekile ukuyisebenzisa, ihlala isikhathi eside futhi igqoke kanzima
2. Iphedi kayinki ingafakwa ohlangothini olulodwa kuphela, iqinisekisa ukuthi ikhwalithi yokuphrinta izohlala iphelele ngemva kokugcwalisa kabusha.
3. Ukufanisa ilebula engenalutho kanye netheyiphu enezinhlangothi ezimbili kuyatholakala, kuyenza isebenziseke kalula.
