Remove all ink cartridges from the printer and gently clean the contacts on the printer and cartridges. Unplug your printer and leave for 10 – 20 minutes. Plug the printer back in and wait for the message to insert new cartridges. Replacing any that are almost empty, install all inks back in the printer.
It means that your device is not able to work up to its maximum potential. It is a common message that indicates that the print head of the Brother Printer is encountered with the temperature error or might have an internal electric issue.
Print Unable 0B means there is a mechanical malfunction of the Brother machine. 1. Press and hold the power button to turn the machine off, wait 5 seconds, and then power the machine on.
During a print job, the printer stops feeding pages, an E4 error displays and the Resume light blinks. This indicates that paper might be jammed inside the printer. Note: Paper jams can be real or false.
According to the manual 4F means “DXE IPL is started“, but nothing else or more info to develop. Also the only beep codes the manual refers are an infinite loop of Long + a number of short beeps, not a single instance of 2 rounds of three long beeps.
1: Check Printer Power, Cables, and Paper

Check that the correct paper is properly loaded into the printer and is not jammed. Replacing damaged cables, plugging in loose or disconnected cables, and fixing paper jams as necessary may resolve the issue.

Error code 55 and the error message “Replace Laser Unit” are common for Brother printers. The error code appears on the display when the laser unit has reached the end of its life cycle. It is necessary to replace the laser unit every once in a while, because worn laser units will lead to a poor printing quality.
“Print Unable 04” indicates that a hardware malfunction has occurred.
Error code 4 shows the Error message “you have been disconnected from Call of Duty, Modern Warfare servers.” and asks you to visit the Activision support page. This error is most commonly encountered while connecting to the Warzone servers.
However, for the most part, the E4 error code means that the unit is entering defrost mode. You will hear a difference in the fan speed when your unit changes. When the fan motor slows, it sounds like the unit performs as an air purifier or dehumidifier. It basically just passes air over the unit without cooling it.
Causes of Motherboard Failure:

Electric and voltage fluctuations. Dust particles, smoke, debris, etc. Liquid damage. Overheating caused my fan failure.

Common symptoms of motherboard issues are similar to CPU problems: The system does not display anything; an error code appears; one or more beeps occur; the system locks; the system reboots; a Windows BSOD (blue screen of death) appears; or one or more of the ports, expansion slots, or memory modules fails.
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.

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.
