Most kits accomplish this by supplying a small soldering iron with an attachment on the end to create the hole on your laser printer toner cartridge. Simply let the soldering iron heat up and press the attachment onto the cartridge - it creates a hole which can be sealed using a supplied plastic cap. After doing this you can refill the toner cartridge as often as you like. The advantage of this system is that no working parts of the cartridge are touched - so there is no chance of damaging anything.
