Turn off the HP printer and unplug it from the power source. Also, shut down your computer and unplug any external devices. Wait for a few minutes and then plug in the printer and turn it back on. Finally, turn on your computer and check if the error state has been resolved.
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
Make sure your devices are properly connected with each other, and the network or the cable you use to connect these devices is normal. You can also try restarting your HP printer. Turn it off completely and unplug the power cord, leave it for a couple of minutes, and then plug the cord back and power on the printer.
Fatal Error

The yellow tape seal has not been removed from the ink cartridge. Turn off the printer, then turn it on again. The ink out lights come on and the print head moves left. Replace the ink cartridge with a new one.

The paper might not be engaged with the feed rollers. The paper-width guide is pressed against the paper stack too tightly. The paper tray is not completely inserted into the product. The paper settings in the print driver do not match the paper loaded in the paper tray.
Most commonly “Cartridge Problem” means that your HP printer simply cannot recognise the colour or black ink cartridges. Thankfully however this error message can usually be cleared with some basic troubleshooting.
a misprint or misspelling in a text.
1. Paper Jams. Paper jams are a common problem for printers, resulting in time-consuming and frustrating delays. It can occur when loose sheets of paper get stuck in the rollers or feeding mechanism of the printer.
In computing, a fatal exception error or fatal error is an error that causes a program to abort and may therefore return the user to the operating system. When this happens, data that the program was processing may be lost.
Clean the Cartridge Contacts: one of the most common reasons you might get a cartridge problem error when your cartridges are new and full is the contacts on the cartridge might be dirty or otherwise obscured from making good contact with the electronics in the printer head carriage.
Verify the ink cartridge(s) is inserted properly. Some cartridges snap in place, and if they are not inserted fully, the printer won`t print anything. If a lever is moved from its original position to allow for installation of ink cartridges, ensure it is returned to its original position.
Take-home Message

To summarize, all (or almost all) HP`s cartridges are refillable. Not all the chips can be reset or overridden, but HP will always leave a refill solution for you.

Error Code 51.1 says Printer Error No Kidding.lol
ANSWER : Sometimes turning off and on will allow you to print a few pages. The error is a beam detect error. The only real fix is to replace the laser scanner unit. Could be a loose connector on the scanner or DC controller from the scanner. That’s unlikely. You could try the only other free fix which is to open the scanner assy. and clean all the mirrors inside. The dust could obstruct the laser beam enough to cause the detect error.

message error: ADF paper jam
ANSWER : There is a thin plastic arm that the paper pushes on. It is spring loaded. If it doesn’t return and unblock the sensor after the paper passes it, you get the paper jam warning. I’m guessing that is the spring you are referring to.

Error message reads remove and check right cartridge
ANSWER : You can try cleaning the contacts on the back of the cartridge and the ones that they contact in the printer. Other than that, you have to replace the cartridge. I once had one that did the same thing. I swapped the cartridge with another printer of the same model and both printers worked fine. I swapped them back and the original printer got the same error. The other printer had no problem with either cartridge. I swapped them back and left them that way.
