refilling

Toner refilling is the practice of refilling empty laser printer toner cartridges with new toner powder. This enables the cartridge to be reused, saving the cost of a complete new cartridge and the impact of the waste and disposal of the old one.
While toner cartridges are commonly refilled with results reported to be good, in at least some cases refilling without full remanufacturing may leave waste toner from each print and paper debris in the cartridge, potentially causing backgrounding problems and producing contamination in the refilled cartridge.The U.S. patent for the "Refillable toner cartridge" was issued to Fred Keen on March 28, 1989.

    Converting To Sealed System - How To Purge Air When Refilling?

    I'm toying with the idea of changing my vented system to sealed. I'm OK with what needs to be done, apart from one thing.
