The drum unit at the Brother DR-2200 is a wearing part and has to be changed in regularly time lags (12.000 pages) or when the quality of your print outs is no longer satisfying. For this case we provide an instruction that tells you step by step how to exchange the drum unit and reset the counter.
Remove the developing unit with the cartridge from your printer and lay the cartridge aside. Turn the developing unit on the table in front of you as picture 1 shows. Carefully remove the "E"-curl from the axis with a small pliers. Subsequently you can drag the axis out of the drum unit from the opposite side (picture 2). You can remove the axis only from this side because on the other it would snag and damage the electronical contacts. Lay the axis aside you need it afterwards.
When you have dragged out the axis you can carefully remove the cover (picture 3) and lay it aside. Now you can carefully remove the cover with the corona wire as picture 4 shows and also lay it aside.
We recommend wearing latex gloves while exchanging the drum unit. Otherwise you risk damaging or polluting the drum. Please do not remove the protective paper from the drum before you have correctly build it in. Remove the drum as picture 5 shows and insert the new one in the same direction. Now you can remove the protective paper. Take the recently removed axis and insert it into the drum unit from the same side (picture 6). Now put the cover onto the other side and finally put the "E"-curl back into its position on the axis.
Now you can insert the cartridge into the developing unit. After reinserting the developing unit with the cartridge into the printer you need to reset the counter. You can find instructions for that below.
Refill toner and toner powder may cause serious health problems if not handled carefully. We recommend always using breathing protection or suction chambers while filling toner cartridges. Furthermore, toner powder and refill toner can be highly flammable with an appropriate oxygen mixture. Please note as well, that you should touch the photoconductor drum in no case or expose it to direct sunlight. This could lead to faulty print-outs. Octopus Office will not take any responsibility for success or failure of the described procedure.
