Three refills, and maybe then some 
If you’ve been following us since the early 1990s (and who hasn’t) you might know that we put “our corporate 
neck on the chopping block and say that the rule of thumb is three refills, and maybe then some”. 
As far as problems due to “wear and tear” go, the HL-L2300D is example of “and then some”. During testing we 
got multiple refills out of the starter cartridge, for example. And did nearly 11,000 test prints all told. 
“Toner Ended” message? 
Delve  deeply  enough into  the  PDF  User  Guides  for  this family  of  printers,  and  you’ll  find  the  suggestion  that 
sometime after you’ve repeatedly pulled the trick of “resetting”, the machine won’t have it any more and then 
you’ll get the “Toner Ended” status. 
Long story short: we did 6 refills and printed 10,911 copies while mixing a refilled starter cartridge with refilled 
bought cartridges willy-nilly. At no point were we stopped from printing. So we’ve released this product on the 
basis that the reset/refill technique is good for at least 10,911 prints (as we weren’t able to provoke or witness 
a “Toner Ended” message during testing). 
The possible “hard reset” solution of the future 
Should  the much  anticipated  “Toner  Ended”  message  appear.  And  should  that  state  be  insuperable by  the 
techniques found in these instructions. Or should a reset technique fail for your particular model, we do foresee 
a fix. 
It’s a catch-all fix for all models that use the TN-2310 or TN-2320 cartridges. In fact, it’s the one the cartridges 
themselves use. 
It involves putting a wheel found in the cartridges  back to a certain position. That achieves the reset  and we 
call it a “hard” reset because it depends on physical mechanisms. 
The draw back is that, at the time of releasing this product, we don’t have independently produced reset wheels 
available. And starter cartridges (probably not by any accident) don’t have them on. This would mean that the 
only  way  to  get  a  “hard”  reset  on  a  starter  cartridge  would  be  to  buy  a  Brother  original  cartridge  and 
cannibalise the reset wheel off that. 
Although, we, in fact did exactly that (and that’s how we know all this is true), of course people are interested 
in refills precisely so that can avoid buying original cartridges. Duh! 
For that reason, we’re releasing this kit on a “soft” reset and a prayer as the best way of helping people save 
money quickly. 
We would look to usher in a “hard” reset solution were it seen to be needed once it were technically possible. 
Other things the machine uses 
Don’t forget that as well as the toner cartridge, your machine also uses a drum unit … 
DR-2300 quoted as yielding 12,000 prints 
It has its own duty cycle which isn’t affected  by  whether or not you refill the toner cartridge. See the section 
“Consumable items” in your PDF User Guide for more on that.
