HP PSC 1315 all-in-one Problem

I have a problem in my HP PSC 1315 all-in-one printer, scanner and copier.
After I turned on that device then I print a document it will successfully print but it will never scan any document. And if I scan at first from the time I turn it on it will successfully scan but it will never print again.
I tried to reboot my computer and turned off that device but not happened.
Please help.
