BROTHER HL-L2300 SERIES TN630/660 TONER CARTRIDGE REMANUFACTURING INSTRUCTIONS
Since the waste toner is transferred back into the supply of the toner cartridge - once you print with a bad toner cartridge,
the drum unit will become contaminated. Even when you change out the toner with a good properly recycled or new OEM cartridge,
the drum unit will transfer some of the bad toner back into the good toner cartridge, which will again cause backgrounding.
Both cartridges will be contaminated again - it can be a vicious circle.
The remaining "toner" in the toner cartridge, when toner low is reached, is just below the bare minimum that can maintain the
proper charge level. When the "change toner" light comes on, the toner will not charge up to the proper level and will cause
the backgrounding. As the toner cartridge reaches the end of its useful life, the printer senses the low charge level in the toner
supply and will try to keep the charge level up. This constant charging keeps an almost "empty" cartridge from backgrounding.
Once the printer cannot get the remaining toner up to the minimum charge, the "change toner" light comes on. The cartridge at
this point will still be printing properly. If you were to take that same cartridge out of the machine for a few days, and then put it
back in the printer without doing anything to it, the cartridge will background. This will happen because the charge level that the
printer was trying so hard to keep up has dissipated, and the materials left can no longer accept a proper charge.
WHAT DOES THIS ALL MEAN?
1. Make sure that your cartridge technicians thoroughly clean out the supply chamber of the toner cartridge.
2. Clean the developer roller with an approved developer roller cleaner (NOT alcohol - that will strip off the conductive coating)
3. In the event that they forget, and you have a backgrounding cartridge. The toner must be completely cleaned out again (do not
use the toner over), and NEW fresh toner MUST be installed.
4. Clean the developer roller (again) with an approved developer roller cleaner (NOT alcohol).
5. The drum unit then has to be taken apart and cleaned out with emphasis on the cleaning roller and transfer roller. This is a very
simple process but very necessary once it is contaminated.
According to our tests, there will be approximately 45-50 grams of toner left when the cartridge is spent. This is normal. The toner
left however, as stated above, is waste toner/paper dust only and must be thrown out or there will be backgrounding issues.
