How to Identify and Fix Common Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

Turn the printer off, and then on to delete any stored fonts or macros and clear the temporary memory. Try again to copy, fax, or print. If the issue persists, make sure the printer is running the latest version of firmware available. Print a Configuration Report from the control panel.
A supply memory error happens when the metal contacts / chip on an HP toner cartridge doesn`t correctly connect with the corresponding contacts inside the printer. The printer cannot detect the toner cartridge and displays the `Supply Memory Error` message on the printer display panel.
Volatile memory requires power to store the information. Deleting volatile memory is easy: Simply shut down or unplug your printer for a minute or so. Most printers also have non-volatile memory (a hard drive) that is stored until you physically delete it.
Supply memory error is an error message displayed on HP printer screen when the supplies are incompatible or undetectable. Once you receive this error message, you can no longer print with the supplies installed. The most common supply memory error codes are 10.10. 00, 10.00.
The printer is unable to read the toner cartridge data. The toner cartridge is present but defective. When this error occurs, a question mark appears on the gas gauge of the supply or supplies with the error.
The Memory Test, built into the BIOS for HP notebook computers, tests the condition and integrity of the installed memory. Run the test to identify potential issues if the computer does not start or operate properly.
Most printers will stop working when they`re out of paper, ink or toner, or if the unit detects an issue with the ink or toner cartridge. When this occurs, you might receive an error message or notice blinking green or amber lights on your printer.
Use HP Print and Scan Doctor (Windows)

Use HP Print and Scan Doctor on your Windows computer to help diagnose and fix printing and scanning issues. Make sure paper is loaded in the main tray, and then turn on the printer. Download HP Print and Scan Doctor, and then follow the prompts to install and open the tool.

“Out of Memory” means the machine`s storage capacity is full. The amount of memory used depends on the amount or type of data on the documents being copied, faxes, or printed from a computer.
Just take out your toner cartridge. If you find an orange color notch on the left side, just remove it. Re-insert the cartridge and restart the printer. This should resolve your issue.

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.
