oh .. sorry to hear about the accident. Allah sab ko apni hifz o amaan main rakhay.
About computer scanner, I am not confirm but I think I read a board or something on Jail Road where there are lots of showrooms (coming from mozang chowk when you turn left on jail road ). You can look and ask around there. Again I am not confirm, so better ask around on other forums , maybe you will get a recommended and confirmed workshop location.
