HP scanner not recognized by MacBook Pro 17" 2010
I have an all-in-one HP PSC 2210 Printer/Scanner. When I bought my MacBook Pro 17" 2010 last year, I could use the scanner by plugging it to the USB port and clicked on System Preferences > Print & Fax > Scan tab. I did not have to install any driver or software for the scanner. However, after several Software Updates, especially after the HP drivers update, the scanner could no longer be used. When I clicked on Scan tab, I got an error telling me that the scanner not recognized. I tried deleting the scanner and installing it again, but it did not work. Worse, the Scan tab is now missing. I can print just fine, but I can no longer scan because the scanner is no longer detected. I have fully updated the OS X to 10.6.7. Still, the scanner did not show up. How do I get the scanner to get recognized again by Print & Fax? It used to work, so I believe that this issue can be fixed. I am a first time Mac user, so please tell me how to fix this. I hope Apple engineers read this post. When I searched Google, I found out that many people have the same problem, HP scanner not recognized by Mac OS X.
