Gram Laser

Laser toner refill question?
I bought a Samsung SCX-4521F laser MFP. Right now, the toner is good, but I want to get ready to change the toner in starts to run out. On ebay.ca We talk about: 65 grams toner refill kits + reset fuse for a model for $ 5CDN (+ $ 5 shipping). This sounds interesting tho I have no idea 65 grams is enough to replenish the toner cart and what the heck is a reset fuse? Thank you
A reset fuse is a chip in the cartridge. This view how much toner is left and how many more copies, you get out of cartridge.Most Re-manufactured toner cartridges already been refilled and reset for you.Saves you very trouble.ie came across your site few weeks ago.You should take a look.Good Luck
