Firts of all, one big greeting form Croatia.

I have one problem with the device CP520. Before starting a new race, I have done "CLEAR MEMORY",and then I had start with new race, and after 10 or 15 start bibs, printer starts to print out some datas from races made before, and it's not stopping. I have even "RESET" the device, but it happens again. This device is not connected to the computer.

Does anyone have some idea what shall I do???

Thank you in advance

Have you tried running the timer solely on the external power supply while going through the reset process?
