Frequently Asked Questions
Do I need to replace the drum units every time I change an OKI MC780 toner cartridge?
No. The image drum units (45395705-45395708) are separate long-life items rated for 30,000 pages, whereas toner cartridges yield between 11,500 and 15,000 pages depending on the colour.
Why does black toner require more frequent replacement than cyan, magenta, and yellow toners?
Although the 45396208 black toner cartridge yields 15,000 pages compared to 11,500 pages for each colour toner, high-volume office environments generate a higher proportion of monochrome text documents, accelerating black toner consumption.
When should the fuser unit and transfer belt unit be replaced on the OKI MC780?
Both the 45380003 fuser unit and 45381102 transfer belt unit have a rated page life of 60,000 pages, meaning they typically last through several complete sets of toner cartridges before requiring replacement.
