If there is no image preview on a scanner, it could be due to several potential causes.
First, the scanner may not have a built-in preview feature. Some scanners are designed with only basic scan functions and do not offer image previews. If this is the case, you can still scan the document or photo, but you won’t be able to see an image preview before you send it to your computer.
Second, if the scanner has a preview feature, it may be because the scanner’s software or driver is not installed correctly. Ensure that the correct driver or software is installed and updated.
Third, the scanner may require a different type of cable connection than you currently have. Many scanners use USB cables to connect to a computer, so try using a different type of cable if necessary.
Fourth, the scanner may be experiencing hardware or software issues. Unplug the scanner from the power source and check the connections. Make sure that the device is connected properly and that none of the wires are loose. Also, check the device’s status in Device Manager.
Finally, the image preview feature may be disabled in the scanner’s settings. Refer to the manufacturer’s instructions for guidance on enabling the feature.
Ultimately, if none of these solutions works, you may need to contact the manufacturer’s technical support team for further assistance.
