What is the page life?
What does a belt unit do in a laser printer?
As the belt wears over time, print issues such as colour shifting, streaks or blotches can occur — replacing the belt unit restores accurate colour performance.
How is a belt unit different from a drum or toner cartridge?
• The drum unit transfers that toner to the belt using static charge.
• The belt unit then transfers the combined colours onto the paper.
All three parts work together to produce the final printed page and each has a different function and lifespan.
