Frequently Asked Questions
Why would a workplace standardize on this 5-pack?
Because one cartridge code — TK312 — serves six different printer models, a stockroom can hold a single item instead of six. Five units on one shelf keep every machine in the fleet supplied without juggling separate orders. The 5-pack is $285.81.
Which fleet models does it standardize?
The FS-2000D, FS-3900D, FS-3900DN, FS-3900DTN, FS-4000DN and FS-4000DTN all take this same black cartridge. Any unit from the pack drops into any of those printers.
Is installation consistent across all five cartridges?
Completely. Every TK312 seats the same way: open the cover, remove the spent unit, slide the fresh one in until it locks. Whoever handles the swap — office manager or IT — follows one identical routine every time.
Will heavy and light printers drain cartridges at the same rate?
No, and that is normal. The 12,000-page rating assumes standard coverage; a printer producing dense reports all day will finish a cartridge sooner than one used for occasional letters. The rating helps you forecast, not promise an exact count.
What protection covers a stockroom purchase like this?
Each of the five cartridges has a 1-year warranty and free returns lasting a full year, counted per unit rather than per shipment. Help is available Monday through Friday, 9 AM to 5 PM CST if a unit misbehaves.
How is a pack this size shipped?
From the closest warehouse among our IL, PA, GA and CA locations. For delivery timing and how returns work, see our shipping and returns page.
How should the five boxes be arranged on the stockroom shelf?
Flat, in a single row, with the oldest delivery at the front. A TK312 taken from the front of the row is automatically the longest-stored unit, and a glance at how many boxes remain tells anyone whether the fleet is stocked or running thin. Keep the row away from radiators and sunlit walls, and the last cartridge out of the pack is in the same condition as the first.
How do we keep track of which printer took which cartridge?
Keep a simple issue note with the shelf stock: date, machine, and the initials of whoever fitted the TK312. With six models drawing on one cartridge code, that little log is what turns arguments about disappearing toner into a clear record — and it quietly reveals which of the FS-series machines is eating cartridges faster than the others.
At what point in the pack should the next order be placed?
When the fourth TK312 leaves the shelf. One sealed cartridge still in reserve means the fleet can absorb a dry machine anywhere while the new delivery travels, and ordering at that point keeps the reorder a routine purchase instead of an emergency. Waiting for the fifth box to open before acting leaves six models sharing a single cartridge's worth of cover.
Where do the five empty cartridges end up?
Back in the stockroom, each in the box its replacement came from, gathered in one collection carton. Five TK312 empties accumulate over the life of the pack, and holding them boxed in a single place lets the whole lot leave together through your normal recycling channel. It also keeps the shelf honest: sealed boxes are stock, boxed empties are waste, and nobody confuses the two.
About This 5-Pack
Built for the supply shelf rather than a single emergency, this five-cartridge TK312 pack from Kyocera-Mita suits offices running several FS-series printers side by side. One SKU, six compatible models, five cartridges rated at 12,000 pages apiece — restocking becomes a glance at the shelf instead of a purchase order. At $285.81, with a 1-year warranty and 1-year free returns behind every unit, it is the low-maintenance way to keep a small fleet printing.
