EPSON Stylus PHOTO 81 0/820/830 Rev isi on B Operating Principl es Overvie w 31 2.1.3 Carriage Mechanism The Carriage mechanism consists of CR motor, Carriage u nit (inclu ding the Printh ead and CR guide s haft), CR timing belt and CR home positi on s ens or (H P/ PE s ens or) etc.
EPSON Stylus PHOTO 81 0/820/830 Rev isi on B Operating Principl es Overvie w 32 2.1.4 Paper Loading/Fee ding Mechan ism The following s tepping motor controls the Paper loading/feeding m echanism on this printer.
EPSON Stylus PHOTO 81 0/820/830 Rev isi on B Operating Principl es Overvie w 33 For your reference, the top or the end of a pap er is usually detected with th e HP/PE sensor. In case that the HP/PE sensor cannot detect the top of a p aper in the paper loading sequence, the printer indicates the "Paper out error".
