Frequently Asked Questions
Why would a workgroup buy three cartridges at once?
Because the FS-3900DN rarely gives much warning before it stops. With this 3-pack, one TK-322 goes into the printer today and two stay sealed on the shelf, so the next two changeovers are handled the moment the toner message appears — no emergency order, no machine standing idle while a delivery is in transit.
Is the 15,000-page figure per cartridge or for the whole pack?
Per cartridge. Each of the three 1T02F90US0 units in this pack is a full cartridge rated at 15,000 pages at standard coverage for the FS-3900DN, exactly like the single. The pack changes how many you hold in stock, not what each one delivers.
Can the three cartridges be split between two printers?
Yes. The units are individually sealed, so nothing ties them together — one can go into the accounts department's printer and another into the one by the warehouse office, as long as both machines take the TK-322. The third simply stays on the shelf for whichever runs dry first.
How should the two spare cartridges be stored?
Leave them in their sealed packaging, lying flat in a dry cupboard or drawer away from radiators, direct sunlight and damp. Stored that way, a spare keeps properly for many months and is ready to drop in the day it is needed. Writing the delivery month on each box makes it easy to use the oldest one first.
If one cartridge from the pack develops a fault, what happens?
Each unit is covered on its own. A problem with one cartridge is dealt with under the warranty for that cartridge alone — the other two are unaffected, and you are not asked to send the whole pack back. Just tell us which unit is misbehaving and when it was fitted.
What is covered, and how do returns work?
The pack carries a 1-year warranty and 1-year free returns; our shipping & returns page explains the process. Parcels leave from the nearest of our IL, PA, GA and CA warehouses, and help is available Monday to Friday, 9 AM to 5 PM CST if anything about the order needs sorting out.
What do we do with each empty as the three cartridges rotate through?
Give the empties a home — one box by the printer where each spent TK-322 lands as it comes out. When the second spare goes in, the empties box holds two units; send them out together through the office recycling or waste route rather than one at a time. It keeps the rotation tidy and the count of empties quietly confirms how far through the pack you are.
When should the next 3-pack be ordered?
The moment the last sealed cartridge is fitted. At that point the shelf is empty but the printer holds a full 15,000-page TK-322, so there is a long, comfortable window for the next pack to arrive. Ordering on that trigger — rather than waiting for pale prints weeks later — keeps the workgroup's no-idle-printer rhythm intact without anyone having to watch the stock.
Can we learn anything from the first cartridge about how the other two will last?
Yes. Note the install date and, if you can, the FS-3900DN's page counter when the first 1T02F90US0 goes in and when it comes out. That gives you this department's real per-cartridge life under its actual mix of invoices, statements and reports. Multiply by two and you have a sound forecast for the remaining stock — and a basis for judging whether three-at-a-time remains the right order size.
One spare spent the summer in a warm stockroom. Should we still use it?
Almost certainly yes. Heat is a reason to store cartridges elsewhere, not usually a reason to discard one: keep the TK-322 sealed, move it to a cool, dry spot, and before fitting it, rock it gently side to side so the toner levels out. Judge it by its output once installed. If it prints badly despite that, it stands under the same 1-year warranty as any unit in the pack.
About This TK-322 3-Pack
This is the rotation-stock option in our Kyocera-Mita compatible range: three individually sealed TK-322 black toner cartridges (part number 1T02F90US0), each rated at 15,000 pages, for $123.05. It suits a shared FS-3900DN that several people rely on — one cartridge working, two in reserve — so a toner-empty message becomes a two-minute swap instead of a stopped printer and a rushed purchase.
