I have a brother HL-4040CN and did my first refill unsuceesfully. I only filled it 1/2 full and it is dumping excess toner out I have cleaned it three time and tried to make sure toner was evenly distributed. The printer was in fine working order, so I am thining the toner is too fine ? The bottle says it is for the TN-110. So, any help would be great.

Hello,

In order to have a successful refill ALL the original toner must be vacuumed from the cartridges and all 4 cartridges must contain the same formula of toner.

Uni-Kit released a new formula for TN110 and TN115 Brother in September, 2008. This new formula has less interference with the OEM toner than in the past, and works very well even if you dont fully empty the OEM cartridge before you fill it.

There have been no reports of leakage with this new formula, and its working very well compared to OEM.

This can be due to 2 things:

1) The compatible toner that is added to the cartridge is not mixing properly with, or is interfering with the OEM toner,
or
2) Leaking cartridge

Problem #1 is the most likely cause of a "leaking cartridge". What is happening is that there is too much OEM toner left in the cartridge, and/or on the developer roller. The reason we do not see this problem very often when refilling professionally, is that when a cartridge is properly remanufactured, all of the old toner is vacuumed out of the cartridge, and the developer roller is blown off. This eliminates the "contamination." As you use the cartridge, this problem will get better as the new toner is "cleaning" the old toner off the developer roller. It is wise to totally dump out (or vacuum out) any remaining old toner, and if possible "blowing off" the developer roller with a can of compressed air... This should eliminate this problem...

The other cause of "blotching" could be the result of a leaky cartridge. Toner can leak from behind the developer roller, where it sits against a mylar strip. You must check there is no damage to the mylar strip, sometimes you can gently push the strip back out with a flat-blade screwdriver, this closes the gap. This is of course a problem that would not get better with use.
