How do I know if I can update the software or firmware in my scanner?

WS1040, WS1065: Check our scanner downloads page to see if there is an update.
WS1080/88, WS1095/98 & TRX 1/2– Launch the EZ Scan software that came with the scanner. Normally it will automatically look for all updates. If launched in the last few days and you want to force the check, click on the Updates tab and select Check for All Updates.
