Product Description The ink cartridge is the most important element of the Lexmark printing process, so Lexmark carefully engineers its cartridges for optimum performance. Installing a new Lexmark print cartridge is almost like getting a brand new printer. Lexmark develops and manufactures its cartridges using a full range of inkjet technologies, from precision printheads to specially formulated inks. In fact, Lexmark's printhead technology has important advantages over that of competing brands, including a higher ejection pressure and greater packing density, resulting in a smaller cartridge that makes great-looking prints. Lexmark takes inkjet quality to unprecedented levels with deep, rich black inks and the brightest and widest color ink spectrum to produce spectacular output. Amazon.com Lexmark's number 83 color ink cartridge provides quality output for many Lexmark Products, including Lexmark X85, X145, and X5150 all-in-ones, plus Lexmark Z55, Z55se, Z65, Z65n, and Z65p Jetprinters. Designed with two separate nozzles and a large print swath, this cartridge will ensure consistent print quality and increased print speeds on a wide range of media. Each cartridge yields approximately 450 pages.
