"Jam in: Print Paper Path" sign

[Jenny12345]

I have been using a HP LaserJet M1217nfw MFP since 2013.

While I was printing 10 pages yesterday, all of sudden 9th page was stopped

and a blinking sign of "Jam in: Print Paper Path".

 But, there is no paper jammed, even no part of tiny piece of paper in my printer.

A few possibilities:

1. Check and clean the paper pickup/feed roller. If the roller(s) are dirty or worn slick, they won't pick the paper and can cause that error.

2. A sensor arm may be stuck, broken or the sensor may be dirty or no longer working. Try blowing out the paper path with a can of compressed air.

3. Printer is stuck in a state that needs a power reset:

Power Reset:

First, make sure the printer is plugged straight into a wall outlet and not a power strip, surge protector or UPS.
With the printer plugged in and powered ON, disconnect the power cord from the printer. This will hopefully dissipate any electricity stored in the printer that could be hindering it.
Wait at least 30, preferably 60 seconds.
If there is a power switch, turn it to the OFF position.
Plug the power cable back into the printer.
Turn the printer ON with the power switch.

Good luck.
