Oliveti copier d-copia16W

Question

We have bought one Oliveti digital copier model: d-copia16W, the toner cartridge which comes with the machine has been finished now but unfotunately that cartridge is not available in local market.
Some of my friend told me above Oliveti model is simialr with Sharp AR-5316. I have tried the cartridge of Sharp AR-5316 but it did not work and some error appears on display.
Can anyone help me out to solve my problem.
