Problem:

I reported an issue with my HP Smart Tank 750 printer's scanner, where the top part of scanned images is distorted. I noticed the problem when scanning receipts, though it may have been occurring earlier. I tried different scanning software and performed a reset, but the issue persisted.

Steps:

  1. Scanned grid paper. You can see distortion results:

  2. The support representative asked for details like the device I used for scanning, any recent changes, and physical damage to the printer. There is no damage.

  3. They suggested a hard reset, which involved unplugging and reconnecting the printer after a minute. I did that but the issue remained.

  4. I observed that the scanner mechanism seemed to get stuck, which led the support representative to suspect a hardware issue.

  5. The representative asked for a video of the scanner's operation and confirmed the issue as a hardware defect. See videos

  6. I was advised to take the printer to an authorized service center in Metro Manila, as the problem requires hardware servicing. The support representative provided a links to locate nearby service centers.
