I've been having this problem since last month. When i try to scan with my Epson Tx121, an error like this pops up on my window:
Cannot communicate with the scanner.
Make sure the scanner is on, correctly setup and connected with no errors indicated.
For detailed information, see Solving Problems in the User's Guide.
Now, i'm pretty sure my Epson TX121 is communicating well with my computer since i don't have any problem with printing.
I'm pretty sure too than my scanner can scan since i can still use my Epson TX121 as a photocopy machine.
I've searched throughout google, only found a few resources which i have tried, but to no avail.
I had this error early December, after a few attempts to fix which didn't yield any result, i did a system restore. I'm not sure if it helped but a few days after, i was able successfully scan. Then after a couple weeks of the same month, i tried to scan again, but the error reappeared. i did a system restore today but it didn't help this time.
So can anybody help me?
