Horizontal lines when scanning (digital glitch, not debris on scanner)

[Jamiwa]

Hello, can anyone advise on how to resolve horizontal lines appearing when using the flatbed scanner (Hp Officejet 6600) ? 

This scan function/device has worked fine for a year and suddenly malfunctions on every attempt to scan.  I have gone through several steps in trying to resolve, including resetting/rebooting the printer and computer.   To clarify, this not a matter of debris/ink etc. on the scanner bar or glass; it is a digital glitch (see attached screenshot image).

I am unable to find many references to this particular issue on HP forums or elsewhere.  If it helps you offer a response, fyi I am using a macbook, which has worked fine with this scanner/printer until recently with this issue.  The printer function works fine.  Lastly, I just downloaded the most recent HP update for this device through the App Store and it still gives the same error.

Thanks for your consideration.

@Jamiwa, Welcome to the HP Community!

I certainly hope I can help you with the scanning troubles you are having as you are noticing horizontal lines through your scans from your Officejet 6600, to your Mac running Yosemite. To add to the steps you have already tried, here are some of my suggestions for you.

Try these steps in this order:

1. Reset the printing system
2. Repair disk permissions
3. Restart the Mac
4. Click here to download and install the Full Feature Driver: HP Officejet 6600 e-All-in-One Printer series - H711 Full Feature Software and Driver
5. In addition, download this driver: HP Printer Drivers v3.0 for OS X
6. Try scanning again

Also try making a copy from the front panel of the printer to see if they also show any defects.

Tip: Make sure the printer is plugged in directly to the wall outlet, avoiding power bars and surge protectors. This ensures the printer is receiving full power.

I hope to hear the outcome! If you wish to show appreciation for my help, click the "thumbs up" below!

@Rainbow7000, thank you for the suggestion.  I skipped the "repair disk permissions" step and it still worked by executing remaining steps.  The scan function is working properly and the horizontal lines are gone !

The same issue with horizontal lines showing when scanning has resumed.  I have made no updates to my computer operating system, settings, etc. relating to printers/scanners and I have made no further updates to the printer software since the issue was seemingly corrected previously (as showing in this thread).

Somehow, the exact same original issue resumed with no obvious change that may cause it.   In fact, I had scanned two pages with no problem immediately before the third page had the error resume.  No settings changes; just tried to continue scanning....

If anyone can offer any further or alternate suggestion in resolving this, please let me know.  Screen shot example attached of what a scan looks like currently.

Thanks for your consideration,

Hello again @Jamiwa,

I saw that the scanning issue has returned, unfortunately! 😞

I would suggest trying all of the previous steps I mentioned, and in the specific order they are listed. If the lines reappear, next try contacting HP directly to see if you perhaps qualify for a printer replacement. I will leave their contact information below for you.

Step 1. Open link: www.hp.com/contacthp/
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number
Case number and phone number appear.

Good luck! 🙂
