The Lexmark 78C1UC0 is a genuine Unison cyan ultra-high-yield toner cartridge rated for approximately 7,000 pages, suited to users of compatible Lexmark laser printers who print color documents regularly and want fewer cartridge changes.
Recommended For
- Teams that regularly print color-heavy reports, charts, or business documents on a compatible Lexmark printer and want a high-capacity cyan replacement; the cartridge is rated for up to 7,000 standard pages under ISO/IEC 19798 testing.
- Workgroups maintaining supported Lexmark CS521dn, CS622de, CX622ade, CX625ade, or CX625adhe printers that need to replace cyan specifically rather than purchase a full set of color supplies.
- Organizations that accept Lexmark’s Return Programme terms and can return the used cartridge to Lexmark for remanufacturing or recycling after its single use.
