Yellow toner for Lexmark laser printers

The Lexmark C340X40 is a genuine yellow toner cartridge built for compatible Lexmark laser printers. It ships new in retail packaging and contains a single high-yield unit. Offices and home users who print colour documents on supported Lexmark hardware will find it a direct-fit consumable.

Print technology and yield

Laser print technology delivers consistent yellow output across the cartridge life. The high-yield formulation is rated for approximately 4500 pages, reducing replacement frequency during regular workloads. No special power or cooling considerations apply to this consumable item.

Replaces standard yellow cartridges

This high-yield cartridge replaces lower-capacity yellow toner units for the same printer models, cutting the number of swaps needed over time. The upgrade makes sense when print volumes justify the larger fill. Buyers who need cyan, magenta or black toner must purchase those colours separately.
