i have a Samsung CLP-510N... it came with stock cartridges... they are only half full with toner... yesterday i just refilled them to full.. This will give me around 7000 pages at 5% coverage.. the refill kit even included new chips, a pair of gloves for each colour.. and the toner came in bottles that fitted right on the cartridge.. price 180$ (1495 danish kroner/DKK) so that gives me 0.02$ a print

but yeah, i will have to replace the transferbelt and drum... what is the fuser? the thing that's hot?
