Scan scan bar on the printer is continuously moving back and forth.

[GGx3]

The printer is connected via USB to a computer using Vista and also used remotely by a MAC, IPad, and IPhones. 

The scan bar on the printer is continuously moving back and forth, I ran the HP Print Scan Doctor and it found no problem. 

I can print, copy, and scan but the motion of this piece on the device will not stop. 

No change to the issue occurred when I turned the printer off, waited several hours, and turned it back on.

Hi @GGx3,

Welcome to the HP Forums!

I noticed that the scan bar on your HP Officejet pro 6830 printer is continuously moving back and forth. I am happy to look into this scanning issue for you!

First, I would recommend a hard reset, by going to this post, How to perform a Hard Reset, by @Rich1. it is important that the printer's power cable is plugged directly into the wall outlet, and not a surge protector. Please, see this article, Issues when Connected to an Uninterruptible Power Supply/Power Strip/Surge Protector for more information. This applies to Inkjet printers as well.

After the hard reset, I would go through this guide, The HP Printer Does Not Turn On or Respond When the Power Button is Pressed, and watch this video:

(Even though the guide title may not match your issue, I believe the solutions will help.)

The last step I would do is to also make sure your printer's firmware is up-to-date. Getting Printer Updates for HP Officejet 6810 and Officejet Pro 6830 e-All-in-One Printer Series.

Hope this solves your problem, and have a good day!

I performed the hard reset as suggested and viewed the you tube guide. 😟. The scanner bar is still moving. Any other recommendations for a solution?

Hi GGx3,

Thank you for trying the steps I posted, since they did not resolve your issue, I honestly think this is a hardware malfunction of the printer itself. I would suggest to get the printer serviced. Please call our phone support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region. Country-language selector.
