It is not difficult to change the toner, saying that it is easy but also not to the effect. There is a bit of learning in it, and the following is a simple introduction to the drum powder separated drum.

First close the printer power and remove the DR730, then the metal pin on one side of the clamp with forceps, carefully drawn outward force (or the pin nails, directly to the out again after open the drums), in general, this time we can find drum unit can be divided into two parts, the parts with magnetic roller is for powder, and photosensitive selenium is collect part of waste powder.

In the process of replacement, if carbon powder is left on the outside of the printer, it is better to vacuum and clean it with pure alcohol. In addition, the whole replacement process is best done in darker studios to prevent exposure to sensitive drums. In addition, usually drum unit is valid for two and a half years when not opened, but once opened the period of validity is 6 months, the user should pay attention to use in the period of validity, to ensure the quality of printing.

Notes:

While maintaining and replacing the toner cartridges, there are some areas that need to be reminded again:

1. Clean the dr730 should not be used too often, and they are forbidden to be scrubbed with ordinary paper during cleaning.

2. During the above maintenance and replacement process, it is strictly forbidden to touch the surface of the sensitive drum with the hand, while preventing the collision of hard objects.

3, try not to let the brother drum unit is exposed to sunlight or strong light source directly, don't open the barn door on the drum unit, if the time more than ten minutes of continuous exposure to strong light, high photosensitive drum is discarded.

4, to avoid the high humidity, high temperature, cold environment, use and preservation of toner low carbon powder once will be affected with damp be affected with damp agglomerate, affect print effect or cause print color shallow, also in the drum unit from low to high temperature environment, the best is put on hold for a period of time to use.

6,There is an imaging device in the brother toner cartridges, which is the cover of magnetic roller particles, so make sure your drum unit away from the magnetic material such as displays, hard disk, speakers, avoid the phenomenon of magnetization, thus affecting printing quality.
