This error indicates a RAM failure. The specific memory is internal memory not one of the dimm slots. You can try removing any additional memory first to see if the device will boot but likely this is a failure of the formatter and you would need to replace the formatter.
An Er/03 error message indicates the printer failed to pick a sheet of paper to print. Remove the stack of paper from the tray and check the condition of the paper. Reload the paper, and then try to print, copy or scan.
An Er/02 error message indicates that the toner cartridge door is open or not closed completely. To resolve the error, open the toner cartridge door, and then close it completely.
If the trigger cannot be fully inserted, the door is not properly closed and the E02 or E03 error will occur. To resolve this error, you need to ensure that the printer cable is long enough to allow the door trigger to be fully inserted.
Check for obstructions in the carriage path

Open the cartridge access door to get to the carriage inside the printer. Make sure the carriage is not obstructed by gently sliding the carriage side to side. Look for and remove any obstructions in the carriage path, such as crumpled paper or dislodged labels.

Error 53 indicates that the tape is at the end of its roll.
Recommended action. Turn the printer off, wait 15 seconds and turn the printer back on (using the power switch located on the back of the printer). The error code should not appear again.
That error code indicates a failure of the yellow laser scanner. Unplug and leave for a few minutes, also make sure you are plugged directly into the wall and not into a surge protector.
System Error 03:10 – Technical Support

Normally this error code can only be resolved by replacing the Power Supply Unit. Often the error occurs at the same time as a loud mechanical noise coming from the power supply unit. This means the bearings in the cooling fan have failed and the power supply has in-turn failed.

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.
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.
One of the most common issues that users encounter with the Canon Pixma TS3122 is error codes. Error code E03, for example, indicates that there is a problem with the paper tray. This error can be caused by a number of factors, including incorrect paper size, paper jam, or a misaligned paper tray.
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.

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.
