please help

hi all
This is from Noandishan-nokhbe mehvar-fars co, We have a Zprinter model 450 manufactured by Zcorp and we hope that you can help us with a problem regarding this device.
At the moment, the device cannot connect to the computer via network cable and the computer data are not transmitted to the device. The device is alarming the error" unknown printer". It should be noted that after being turned on, the device alarms three times (beeps) and does not boot up. If it is booted by F2, the connection with the device fails due to the cited error "unknown printer".
We will be really grateful to have your response.
Thanks and regards.
