My M277dw is always scanning a white bar on top of any document.

Happens both in scanning and copying.

Can anybody help me?

Thanks.

A warm welcome to HP Support Community!

Power resetting the printer and cleaning the scanner may resolve the issue. Let's try these steps:

Please ensure the printer is up-to-date with its firmware. If you are unsure, you can download and install the latest firmware update from here.

1) Make sure this printer is plugged into a direct wall, not a surge protector

2) Remove all of your ink cartridges from the printer and close the door

3) Remove the power cord from the back of the printer (Do no press the power button)

4) Clean the scanner, refer to step 2 from this document.

5) Plug the power cord back into the printer

6) Wait for the printer to turn on completely, then install the ink cartridges.

Let me know how it goes!

I tried your steps and magically I can get a clean scan now.

Thank you for the help but how is this possible? I thought it is some software/hardware related issue. All I did was cleaning the scanner and power cycled the machine.

You are welcome! Glad to hear that the issue is resolved.

Most of the scan quality issues are caused by improper scanner calibration, fingerprints, smudges, dust, or debris on the scanner glass. Resetting the printer would have forced the scanners to calibrate and cleaning the scanner and scanner lid would have removed any smudges, dust, or debris.
