I have been using my hp officejet 5510 with a 24 inch IMAC purchased about a year ago. Initially I was able to scan photos to the hard drive, but now when I try to scan, I get the error "unable to connect to the device". When I close that error window, a new error window appears "unable to communicate with TWAIN data source". The hp 5510 functions properly with regard to all other functions. How do I fix this problem? (I've tried re-loading the software and re-installing the printer).

Exactly what the previous poster described, except that I'm using a 13" Macbook.
