Scanner in hp printer-cum-scanner is not workingmy printer-cum-scanner, Hp Deskjet F4218 is not working. when i click the scan button, the scanner seems to work but the lamp does not lit.
i have re-installed the driver software;
removed and re-inserted the power plug, restarted my system several times
and verified every possible manner and scan test also shows that the device is working properly.
can any one tell how to make it work?
