Printer toner cartridges are essential supplies for printing machines. These cartridges contain toner powder used for forming text and graphics on a page via electronic charging and heated printing processes in laser printers. A genuine and original toner comes with a manufacturer guarantee to work with matching printers, and follow a manufacturing standard that helps ensure quality printouts and operational benefits. When comparing printer cartridges, look into factors like quality, reliability and productivity that meet office requirements.

Original Printer Toner Cartridges Improve Printer Performance and Protection

Most genuine printer toner cartridges are individually packaged, providing easy replacement as each color runs out. The products contain proprietary toner powder for professional-looking documents with optimal color balance. The toner particles require low temperatures to fuse, reducing the overall energy cost of your printing operations. Genuine brand ink cartridges and toner cartridges help maintain printer operation with consistent quality print results across both text and graphics. Starter cartridges that come with the printer have model numbers that make finding replacements easy with online tools, like the printer ink and toner finder found on most ink and toner sites. Manufacturers provide a warranty on all original printer toner cartridges to ensure trouble-free printing. Using genuine cartridges in your laser printer guarantees proper ink flow throughout the system to minimize smears, streaks and clogs for reliable, high-quality printing.

Different Yield Capacities for Different Applications

Page yield is the number of pages a toner cartridge delivers before running out. Standard-yield units are suitable for users that print charts and reports occasionally. High yield cartridges let you produce multiple large projects, while reducing the need for regular printer maintenance. Extra-high-yield models feature large storage tanks, which hold a larger supply of toner but still fit into compatible laser printers.

Multiple Color Options and Simple Installation

Monochrome laser printers need only black toners to create easy-to-read text, which is critical for documents like reports and contracts. Color models require convenient multipacks that contain individual color print toner cartridges to produce quality color presentations and documents. OEM printer ribbons, ink cartridges and toners easily fit compatible printers for seamless maintenance and reduced downtime. Some manufacturers include installation instructions in their products, so you can be confident that you get the most out of each cartridge.

Built-In Advanced Features Deliver More Value

JetIntelligence® technology in some LaserJet® cartridges helps them keep up with printing speeds of compatible printers for professional-quality prints. HP anti-fraud print technology protects business printing against counterfeits, while print gauge predicts cartridge life so you can replace the old unit on time. A QR Code®, which is a unique ID number and a security hologram, helps authenticate original Brother® toners. Genuine Samsung® toner cartridges and printers work together to optimize NO-NOIS™ technology for quiet operation. Multi-pack and combination printer toner cartridges contain two or more units of the same color, so you have plenty on hand for future projects, and can save on supply reordering time.
