This error code indicates a fault with the Main Motor. Either it's jammed or unusable. Unplug the printer from the power source, leave it for around 30 minutes, . While it's turned off, remove the cartridges, check for any damage, then put them back in. After tha, then reconnect it to the power and turn it on again. If this still doesn't clear the code from the display then you'll need to see a Brother service agent to have the main motor replaced.
Error E50 comes up on the printer when there is an issue with the fuser unit of the printer. It is either the fuser unit is faulty or fuser unit is not clean. This what you can do to get the error fixed--
All "left" and "rights" are when facing the front of the printer. Remove the electrical cord from the back of copier by pulling. Remove bottom tray. Remove the smaller tray that comes out the back that has a LTR/A4 lever. Open front of machine to take out toner and drum just to make it lighter. Leave open. Take off top cover (4 screws and two wire jacks to unplug). Remove screw on back right side near bottom. Remove screw on front left near bottom that holds left side cover. Remove screw on back left near bottom (it holds a piece in the back and the side cover). Slightly pull out that back, left plastic piece (it won't come out all the way yet) and wiggle things around to get the left side cover off. That back left piece that didn't come out all the way has a plastic *** holding it in. To be able to press that *** is why the side cover is removed. Press *** and pull the back left piece out while wiggling things around to get the 3 plastic pieces in the back to all come out. This exposes the fuser. Remove the two wire jack connections. Remove the two screws holding fuser in. One of those screws is big with a spring - don't worry, the spring stays in place. The other screw looks normal, but it is a little longer than the other screws so remember where you lay it. Find the 2 black wires on the fuser leading to the problem piece. Remove the single screw holding it in. Pull it out and clean the wire connections. Now put things back together.
And after this is done reset the printer by--
Switch the machine on. Wait until the yellow data light goes out. Now hold down the 'GO' button AND the '+' button together four about four seconds. The LCD panel will now display a 'RESET COMPONENT LIFE' message. Use the + and - keys to select the fuser unit, and reset it. Turn the printer off. Turn it on again and it will work. Now reset the drum counter , and also the toner cartridge counter in the same way.
Please accept the solution and revert for further assistance.
Hi, The Service Error #50 is basically a Fusing Unit problem and you may
actually find out that you may have to replace that assembly, to
correct that error condition. E50 means fuser malfunction. Try to print a configuration sheet (press
3 x set). If that doesn't work, you've to change the fuser.
There is probably caked ink and dust on a wire connection
that touches the grey roller of the fuser (that has two rollers). It
seems this will happen to a lot of the brothers. You just clean the
connection. It's simple, but you have to get to it by removing a lot
of screws, pieces, and wire jacks. To summarize:
Remove
top cover, and various plastic pieces in the back to get to
the fuser. Then take out the fuser and find the 2 black wires that lead
to the problem piece that needs to be cleaned.
When you have gotten to the fuser, remove the two wire jack connections. Remove
the two screws holding fuser in. One of those screws is big with a
spring - don't worry, the spring stays in place. The other screw looks
normal, but it is a little longer than the other screws so remember
where you lay it. Find the 2 black wires on the fuser leading to the
problem piece. Remove the single screw holding it in. Pull it out and
clean the wire connections. Now put things back together!
This is really specialist work (the taking apart and putting back together) for a simple cleaning end. Not for the faint-hearted! It will either be a complete nightmare or a fun project for you..
I would personally take it to a specialist and get an estimate, and measure that against the price of a new printer. But, if you feel brave and have nothing to lose, have a go.. So you know what the problem is, but can you fix it yourself? Well that's down to you, I can't answer that ;)
The following worked on the 3 of our HL 5250DN printers that stopped printing for no apparent reason with both the status and toner lights on:
1: Turn off power and remove toner/drum
2: Tape the little spring loaded lever just inside the printer on the upper left hand side in the *DOWN* position! Do not replace drum yet and...
3: Turn power on to printer and let it cycle. Status/Toner lights will come on as usual.
4: Turn off printer, remove tape from lever, replace drum and turn back on.
After hours of working on one of the printers, virtually taking the entire thing apart and replacing fusers, toners and drums, I accidently stumbled onto this sequence. When I tried it on the other 2 printers, Voila! Took like 1 minute each. It must cause some kind of reset of the toner detection switch.
I agree with another su=olution. The paper light was blinking on and off sugesting a paper jam. Paper had jammed in the back roller and displaced the small lever out of its slot.
Open rear cover, open paper guide by pulling it downwards so you can see the rollers, In the middle of the guide you will see a black lever about 25mm long to the right of this you will see a small slot. The guide will have been pushed to the left of this slot and the Plastic cam will be bowing toward the front of the printer (about 3mm). You need to pull the 25mm lever towards the rear of the printer and then slide the plastic cam to the right so the blade part of the cam slides into its correct slot. The blade is about half a mm thick and the slot is the same and is about 60mm to the right of the lever Use a torch to see it easier. This is a 2 minute job once you see what is wrong.
Hope we have helped someone out there fix a printer
Open the front cover and leave open while completing the following steps:
Turn the printer off.
Hold the 'go' button while turning the printer on. All panel lights should be on.
Release the 'go' button.
Press the 'go' button 2 times.
Pause.
Press the 'go' button 5 times.
The toner light should be off.
The paper light should be on.
Close cover. The ready light should be the only light on.
Has it worked before? Many of these newer printers can print what are called Postscript documents, and you may have a Postscript driver instaled instead of the regular driver, or both and have selected the wrong driver when sending the jobORyou have an internal circuit board that'sgone bad
Open front cover pressed go button and then on release button and then pressed go button machine shows error and then release button and after that close front cover error clear
the fuser unit is faulty. you need to change out this component to correct the problem. you may have found a small part that popped out prior to the problem.
On these machines the blurry prints is usually due to bad fuser sleeves, or worn out fuser roller and sleeve on the fuser. You may replace the fuser unit or just order sleeve and roller for your model and replace them on the fuser. Will take about 2 hours of your time. To check if the blurry prints are due to fuser issues, just swipe your hand over the printed page and if you have toner dust on your hand, the fuser is not cooking the toner on the paper. Fuser roller and sleeve are bad and need replacing.
If the print quality is still acceptable you may be able to perform a reset on the drum counter. If print quality is bad you will need a new drum. Reset instructions at this site.
Brother HL 2150N Drum Unit Reset Instructions
Try disconnecting the computer from the printer and shutting it down by removing the power cord and then also shut down the computer for a minute or so and then reboot it and check in "Printers" and see if it has anything waiting to be printed and if so clear out the queue. Flashing green light indicates that the printer is receiving data from the computer and/or printing so you shut it all down and cold reboot to clear out the computer confusion in both the computer and the printer.
