Review on Xerox Phaser 6180 - High Capacity Toner Cartridge (6 by Howie Broyles

Bought this a few months before installing. Unfortunately, after installing the cartridge, I encountered the "wavy line", "wavy marks" or "wavy pattern" issue that several Phaser 6180 and 6280 owners have reported on the Revain and Xerox support forums. As far as I can tell the only solution to the problem is to replace the cartridge with a new one (an expensive proposition). My advice: do not keep these cartridges. Buy them only when absolutely necessary and install them immediately.
