Hi @MikeLuke,

Welcome to the HP Support Community

I understand you are facing a false paper jam issue with your HP DeskJet Plus 4155 All-In-One Printer. Not to worry I will help you to get a resolution to resolve the issue.

To assist better:

• Are you able to make a copy fine?
• What application are you trying to print from?
• Have you tried printing from any other application or device?

 While you respond to that, let's perform a power drain: 

• With the printer turned on, disconnect the power cord from the rear of the printer and also unplug the power cord from the wall outlet.
• Remove USB cable, if present.
• Wait for 2-3 minutes, press and hold the power button on your printer for about 30 seconds to remove any additional charge.
• Now plug back the power cable straight to a wall outlet without any surge protector or an extension cord (This is important) and then plug back the power cord to the printer.
• Turn on the printer and wait till warm-up period finishes and the printer is idle
