Please seek assistance from your local HP certified printer technicians or repair shop. Your English is very difficult to understand.
If I pick out the keywords from your post then I would assume you are having a problem with the date and time feature of your HP LJ 3015. The first thing you should do is perform a Cold/NVRAM reset on the printer to wipe out the memory. After the printer reboots then reconfigure the date/time from the configuration wizard.
Problems with the HP Media Center should be directed to a different area of the the HP forums. We only support the printers in this particular area. The best advice we can offer is to uninstall and reinstall the application after downloading the latest update from HP.
