Thank you for posting on HP Support Forums. It is a great place to find the help you need, from other users, HP experts, and other support personnel. I came across your post and wanted to assist you. I see from the post that you are having issues with the Paper Jam on your HP LaserJet printer. I'll be really glad to help you with this,
To provide you with an accurate solution, I'll need a few more details:
Have you tried to clean the rollers and checked if it moves freely?
Have you tried to Clean pick-up roller if it appears to be dirty or have sticky substance, etc?
In the meantime, let's start off by performing a Hard reset on the printer and make sure that the printer is connected directly to the wall outlet and not to the surge protector
Remove all the ink cartridges and then try to perform a hard reset on the printer.
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 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.
Now insert the ink cartridges and then try to print a test page and check if it works.
For more details, please follow the steps suggested in the support document for 'Paper Jam' Error
If the issue persists, I would suggest this could be a printer hardware failure. I would recommend you contact our HP phone support for available service related options. If your product is out of warranty, please choose paid options to get the tech support number.
