The single black ink cartridge contains EPSON QuickDry™ ink ensuring high quality, laser sharp black output. As part of the dual ink cartridge technology the separate black ink cartridge can be replaced individually for even lower printing costs. Epson commits to recycling all printer toner cartridges and consumables which are collected. Following a specific process that allows all toner cartridge parts to be recycled, waste is significantly reduced and materials reused. Epson also provide a complete, free of charge service for the recycling of empty ink cartridges in an environmentally friendly way. Epson - recycling for a better future.
