FS-4100DN

At the top of the FS monochrome printer range, the Kyocera FS-4100DN trades compactness for throughput and stamina. Network connectivity and automatic duplex come standard, and its cartridge is chosen for uptime: the TK3112 black toner, rated for 12,500 pages per cartridge per ISO/IEC 19752 (the family is listed as TK-3100 in European catalogs).
This is the machine for the print room or the busiest shared desk in the building — the spot where the queue never quite empties and deadlines loom daily. Where a lighter printer would be swapped out and forgotten, the FS-4100DN is specified to clear backlogs for years, and the long intervals between its cartridge changes are part of that specification.

Which cartridge should you buy?
A backlog-clearing printer should never be the thing waiting on a delivery. Most FS-4100DN owners should treat the 2-pack as the minimum sensible order and keep the second cartridge in the print room, steps from the machine. Print rooms serving several departments will find their rhythm in the 5-pack, and the 10-pack suits central stores operations feeding more than one high-volume unit. Each step up trims the cost per page; at 12,500 pages per cartridge, even the largest pack is a measured purchase rather than a gamble.
Chip, toner and everyday use
High-volume machines punish sloppy cartridge changes, so make swaps deliberate: let the current job finish, open the cover, and seat the replacement fully so its chip engages the reader on the first try. If output grays near the end of a cartridge's life, a gentle side-to-side rock of the removed unit redistributes the remaining toner for a final run of pages while the spare is fetched. Store the reserve stock flat and sealed; yield ratings assume about 5% coverage, and print-room workloads — statements, forms, reports — often run denser than that.
Frequently Asked Questions
Which toner does the FS-4100DN use?
The Kyocera TK3112 black toner cartridge, rated for 12,500 pages per ISO/IEC 19752.
Can I use TK-3122 in the FS-4100DN?
No. The TK-3122 is built for the FS-4200DN; the FS-4100DN takes the TK3112 only, so check the cartridge code before ordering for a mixed fleet.
How many pages will one TK3112 print?
Approximately 12,500 pages at about 5% coverage. Actual yield shifts with coverage and print settings, as on any laser machine.
Does this printer need a separate drum?
No. The FS-4100DN's ECOSYS long-life drum is designed to outlast the printer under normal use, so you only ever replace toner.
