Hi \r\ni bought a Pixma MG2100 all-in-one-printer but it will not install the scanner driver on my AMD computer under XP SP3. Printer and copying works fine.It will however install on my laptop with same system, and on a Win 7 laptop, with scanner working. It gives error Scangear USB cable not connected, Scanner turned off, error code 5, 156, 61\r\nI have tried all routine checks (uninstall, reinstall, manual install through device manager etc) but no way. It will not update the driver (appears with yellow ! under device manager).\r\n\r\nAny good ideas?
