There’s nothing much to be panicked about as this sometimes happens that your “HP printer says Paper Jam '' but in actual, there’s no paper jammed.
However, you might be thinking that what the actual cause is “when my printer says paper jam but there is none!” Then, let me tell you that, it is reported that 90% of the time the error occurred due to the guides on the paper tray.
So, whenever your printer halts and shows paper jam error, then instead of thinking to clear paper jam on HP Printer, check the paper tray that holds the printer papers. And, if you’ll find the guide that keeps the paper is slightly off, then make sure to neatly stack the paper together in the tray by adjusting all the guides.
And, after doing so, also ensure that no paper is stuck up inside the printer in actual, especially in the printer’s rollers that are near the tray.
After checking up everything, also unplug your printer once and then plug it back after 30 minutes. That’s it! Then, try to give a print command from your printer to ensure whether the error has been resolved or not.
