Homebrew PCBs

Does any one have any info or experience's with different Toners, I recently run out in my Canon LBP1120 and there are refill centres here selling them for around US$20 so no huge loss if I killed it,   anyway I couldn't get the side cover on the cartridge to come apart without trashing it in some way but could clearly see the Plastic Cap under this cover ... so what the hell, I drilled a 5/8 Hole, cleaned up the berries and used a Rubber Seal from a syringe to seal it up. I did get some Toner that was for a Canon NP6650 Copier, the refilled cartridge works fine now but the Toner is a few shades lighter than the origional stuff.

Any comments about what makes toner darker or lighter, I would imagine that just maybe a Finer powder may give better results and of course the actual colour would have something to do with it.

Thanks
Thomas
