In this paper, we state some results on product of operators with closed rangesand we solve the operator equation $TXS^*-SX^*T^*= A$ in the general setting of theadjointable operators between Hilbert $C^*$-modules, when $TS = 1$. Furthermore, by usingsome block operator matrix techniques, we find explicit solution of the operator equation$TXS^*-SX^*T^*= A$.
