I just purchased the HP Deskjet Plus 4155. I set it up, printed off some test paper, and copied some papers as well. After not using it for a few hours the scan bar started moving back and forth about 4 inches. (From far left to where it would start scanning a document.) As long as the printer is awake it continues to do this. There is no errors that are displayed. I can get this to stop 1 of two ways. 1. Lift the scan lid (as if I'm going to scan a paper) or 2. Put a piece of paper in the document feeder that is on the lid of the printer. I phoned tech support, and they insisted that this was normal... Seems really weird that they would want a printer that is constantly making noise, when not in use. If anyone could help me out that would be greatly appreciated.

@Marko1125, Welcome to the HP Support Community!
Let us try these steps to resolve this issue:
Reset the printer
- With the printer turned on, disconnect the power cord from the rear of the printer.
- Wait at least 60 seconds.
- Reconnect the power cord to the rear of the printer.
- Turn ON the printer, if it does not automatically turn on.
- Wait until the printer is idle and silent before you proceed.
Note: HP recommends connecting the printer directly to a wall outlet rather than a surge protector or a power strip.

I reset the printer, the firmware is up to date, and I aligned the ink cartridges. It did not help. The scan bar continues to move back and forth unless I have a paper in the top document feeder or have the scan lid open. What other steps could I take?
So the scan bar moves from where it is in the picture then to the left to fill that little window.
If I have a piece of paper in the top document feeder (over white tab sticking up in pic), or have the scan lid open the scan bar will stop moving

It seems like a hardware issue with the printer. Please reach out to the HP Technical Support team in your region regarding the service options for your printer.
You may create a case on the website to obtain a case number if required. Kindly watch this video to know how.
Keep me posted for any other assistance.
