Ngokombono, inqubo yokuvala icala ilula: amabhokisi angena, i-tape isetshenziswa, futhi amabhokisi avaliwe afakwe i-pallet ukuze athuthwe noma agcinwe.

Kodwa empeleni, ukusetshenziswa kwetheyiphu yokupakisha akuyona isayensi eqondile.Kuyibhalansi ethambile lapho umshini wokupakisha, isisetshenziswa setheyiphu kanye netheyiphu yokupakisha kumele kusebenze ndawonye ngokuvumelana ukuze kuqinisekiswe ukuthi amabhokisi avaliwe ngokuphephile ukuze kugcinwe imikhiqizo ngaphakathi iphephile.

Kunezici eziningi ezingathinta ikhono le-tape lokuhlala linamathele kubhokisi.Izimo zemvelo ezifana nothuli, ukungcola, umswakama kanye namazinga okushisa abandayo zingadlala indima ekusebenzeni kwetheyiphu yokupakisha, njengoba kungaba nezici zendawo esetshenziswa kuyo.

Ezinye izici ezingase zibe nomthelela ekuthembekeni kophawu zihlanganisa ukungezwani okuvela kusifakeli sethayiphu esingalungiswanga kahle, ingcindezi evela ekusebenzeni ngesivinini esiphezulu noma izici zokungaphumuli ezingezinhle zetheyiphu yokupakisha.Lezi zinkinga zingaholela ekunwetshweni kwe-tape noma ukuphuka, kube nomthelela omubi kwikhwalithi nokuthembeka kophawu, kanye nesikhathi sokuphumula somugqa.
