Scan Bar Keeps Moving

[Marko1125]

Hey,

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.

Thanks!

@Marko1125, Welcome to the HP Support Community!

Let us try these steps to resolve this issue:

Reset the printer

1. With the printer turned on, disconnect the power cord from the rear of the printer.
2. Wait at least 60 seconds.
3. Reconnect the power cord to the rear of the printer.
4. Turn ON the printer, if it does not automatically turn on.
5. 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

 

Thanks
