Although my C4280 prints and copys fine it will not scan giving me a "USB Not Connected Error" message. I tried new USB cable and also re-installed software still gives same error message. Thanks if anyone can help.
I see that although you can print, you can not scan. Running the Print and Scan Doctor might help. The HP Print and Scan Doctor is a free utility (tool) that helps to quickly resolve common printing, scanning and connectivity issues including but not limited to:
USB: Verifies that the USB connection from your computer to the HP product is working correctly.
Network: Verifies that the network connection between your computer and your network is working correctly.
Device Status Test: Checks for device errors such as out of paper, paper jams, carriage stalls, and paper feed issues, and then provides instructions for fixing the error.
Driver Check: Checks for missing or corrupt driver files.
Device Manager: Checks for problems in Device Manager that would prevent printing.
Device Online: Checks if the product has been paused or set to offline, and then sets the status back to online if necessary.
Print Queue: Checks for and clears pending print jobs in the print queue (a log of print jobs waiting to print).
Port Match: Checks the port settings for the HP product.
Device Conflicts: Checks for conflicts with other drivers, such as other printer brands.
Ink Issues: Checks the cartridges and ink levels for issues that affect print quality.
Print Settings: Checks and adjusts the print quality settings.
Test Print: Prints a test page for print quality evaluation, and provides options for cleaning and aligning the printhead if necessary.
Scan Tests: Checks the scan mechanism, drivers, and registry entries.
If that does not resolve the issue, post back and let me know if there are any symbols other than green check marks and what they are next to of course. The wrench is not always easy to spot as the wrench and the check mart are in the green circle.
If you see only green check marks (), the tool did not find any problems.
If you see green wrenches (), the utility identified an issue and corrected it automatically.
If you see yellow exclamation points (), the test failed and required user action, but the step was skipped.
If you see a red X (), follow the on-screen instructions to resolve the issue.
I look forward to hearing back from you.
