Works Perfect, Much Cheaper Than Replacing The Drum
on February 2, 2012
I'm a hardware engineer and have designed computer components for the last 16 years so I know exactly what goes into the design and manufacturing process of so called consumables like printer/copier drums. If I had a nickel for every time I was told to incorporate a life expectancy of X into a design, well, you get the picture. Printer/copier drums are no different. If you knew the mechanics of what renders the chip useless, you'd understand too. The fact is, the drum in 90+% of equipped printers has a service life far exceeding it's 1 time use capacity and chip life.
These reset chips are quick and easy to install. I would recommend wearing a form of breathing protection while emptying the waste toner. A simple dust face mask would work. Don't touch the metallic looking roller. Other than that, the process takes about 10 minutes and, assuming the drum was in good working order before replacing the chip, your printer should be it's good old self again.
