An E1 error occurs when the paper settings in the print driver do not match the paper loaded in the printer. Go to HP Customer Support, enter your printer model, and then search for Paper Mismatch for the document on how resolve the issue.
There are chips inside the original cartridges to record how many pages were printed and they cannot be reset. As a result the printer reads the chips and tells you that the cartridges are empty, even though they are not. This is why you are getting the “ink low” message even though the ink tank is at full capacity.
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.
Any boiler showing the E1 fault code means that a significant pressure drop has occurred in the system. The fix is to repressurise your boiler. When your boiler is switched off, the pressure gauge should read around 1 Bar – in the green zone on the gauge.
An E1 or E2 error indicates that the paper size setting does not match the paper size that is loaded. Remove all paper from the input tray, and then load the correct paper size. Remove any paper from the input tray. Slide the paper width guide as far as possible to the left.
Control displaying F4 E1:

There may be a problem with the Heater or Heater Relays. Power unit down by turning off the circuit breaker(s) for one (1) minute. Power unit up by turning on the circuit breaker(s). Start a time dry cycle.

What can I do? This is typically caused by an incorrect selection made during the LCD prompting after a cartridge is replaced or the lock release lever did not snap securely over the ink cartridge when installing.
Resetting HP Ink Cartridges. There is no reset button on an ink cartridge by HP either. However, the process of its resetting is similar to an entertaining game, and if done correctly, you`ll be back to printing in only a few minutes. Remove your cartridge from the printer and refill it with ink if needed.
Disable the Cartridge Policy feature

In the Device Management pane, select the printers (or printer group) to configure. In the bottom navigation pane, select Config, and then select Supplies. In the Cartridge Policy section, select Off. Click Apply.

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.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).

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.
