Stripey lines when scanning Officejet 7740 Pro

[KMHerveyBay]

I've had this printer/scanner for almost 2 years and it has worked well (printing and scanning) without a problem. I just went to scan a document (double sided) from the ADF and the first page scans with vertical coloured striped lines all through it, whilst the second page scans just fine. When I try and make a copy from the glass, the same coloured lines appear on the printed copy.

How can this happen virtually overnight. The last time I scanned it was fine, now it isn't.

I've done all the cleaning steps recommended and nothing works.

Hi @KMHerveyBay,

Welcome to HP Support Community.

Thank you for posting your query, I will be glad to help you.

It sounds like there could be a hardware issue with your printer/scanner, particularly with the scanning mechanism or the image sensor. The sudden appearance of colored striped lines overnight suggests a malfunction rather than a software-related problem.

Here are a few troubleshooting steps you can try.

• Restart the Printer: Sometimes, a simple restart can resolve minor issues. Turn off the printer, unplug it from the power source, wait for a few minutes, then plug it back in and turn it on.
• Check Scanner Glass and ADF: Inspect the scanner glass and the Automatic Document Feeder (ADF) for any dirt, smudges, or debris. Clean them thoroughly with a soft, lint-free cloth.
• Update Printer Drivers and Firmware: Ensure that your printer drivers and firmware are up to date. You can usually find the latest updates on the HP website or through the printer's settings menu.
• Reset Printer Settings: Try resetting the printer to its default settings. This can sometimes resolve configuration-related issues.
• Inspect Scanner Mechanism: If you feel comfortable doing so, open up the scanner lid and inspect the scanning mechanism for any visible signs of damage or obstruction. Be careful not to damage any components.

I hope this helps.

Take care and have a good day.
