How to replace the drum core of Sharp copier AR2718 AR1818?

I can tell you responsibly that this process is not difficult. I am not a professional repairman, but I can disassemble and replace it freely. Professionals, please don't laugh. I am an individual user. I just like playing with these things. ) My machine is Sharp copier AR28 18. This machine is the same as your 27 18 sibling. Now get down to business:

1. Take out the powder bin: Open the belly cover of the machine and you will see the button of the powder bin (green part). Press and hold the button to pull out the powder bin.

2. Take out the developing assembly: Loosen the screw of the developing assembly (that is, the one slightly different from your surface) and you can pull out all the developing assemblies. Be careful not to tilt at this time, there is a carrier inside, and if you tilt too much, it will pour out.

3. Take out the drum cartridge holder: Before taking out the drum cartridge holder, pull out the cover on the side of the machine (I don't know the name of this piece, which is the upper handle for manual paper feeding). After loosening the side cover, the drum bracket can be taken out directly. There are no screws in this step.

4. Remove a few screws from the drum support, remove the metal mesh, and then remove the scraper. At this time, you find the end with the lock on one side of the toner cartridge, stick it into the two holes with the needle-nosed pliers, and take out the toner cartridge in the opposite direction indicated by the lock arrow.

The reason why I wrote the whole process in such detail is to give it to a novice friend who wants to disassemble the machine himself, because I am also a novice.

The developer mentioned in the above process has a carrier inside. Many people ask how to change operators. You can see how to change it today. I'm not afraid of your jokes. I didn't know where the vehicle was until I got the machine. Hehe, now my machine works as good as new.
