Toshiba e-Studio 305CS Toner Cartridges
Your Toshiba e-Studio 305CS uses the T-FC305 toner series. Supplying businesses with these consumables since Nov 2016, we understand the heavy black-and-white workflow demands of small offices. Because monochrome documents dominate standard business printing, the black cartridge depletion rate far exceeds colour toner usage, requiring planned replenishment schedules. Our 4.8 Google rating reflects a long-standing track record of premium cartridge performance.
Expected page output and replacement cycles
Toshiba calculates T-FC305 page yields using the standard ISO/IEC 19798 coverage testing for colour laser printers. Standard business text printing delivers predictable black output, while heavy graphics and logos accelerate colour toner depletion. Balancing your workflow prevents unexpected downtime across all four toner channels.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |

| T-FC305M | Standard | Magenta | 3,000 | $0.033 |

Frequently Asked Questions
Why does the T-FC305 black cartridge have a higher page output than the colour toners?
Toshiba designs the T-FC305K black toner for a higher output capacity because office printing overwhelmingly consists of text documents, meaning black toner depletes at twice the rate of individual colour cartridges.
Do T-FC305 cyan, magenta, and yellow cartridges wear down if I only print in black?
No, the printer engages specific developer drive gears for monochrome jobs, protecting colour toner powder from premature exhaustion, though small calibration cycles occur during initial warm-up.
Can I swap out an individual colour toner without replacing the rest of the set?
Yes, each T-FC305 colour channel operates independently, allowing you to replace only the specific empty colour cartridge without disturbing the remaining active units.
