Frequently Asked Questions

How do I confirm from the empty cartridge that this is the right replacement?

Read the label on the cartridge you have just taken out. If it shows part number 1T02F90US0, or the TK-322 name Kyocera prints for the same cartridge, this single is the match. It is the black toner cartridge made for the FS-3900DN workgroup printer.

What arrives when I order this single?

One black toner cartridge, factory sealed in its protective packaging. There is nothing to assemble and nothing extra to buy — the cartridge is a complete unit that drops straight into the printer once the wrapping and strips are removed.

What does the 15,000-page rating mean on a machine like this?

The rating is the estimated output of this one TK-322 cartridge at standard page coverage. The FS-3900DN is a departmental printer that can turn out invoices, statements and reports all day, and a 15,000-page cartridge means changeovers are rare events on it rather than a regular interruption to the working week.

How long does fitting it take?

A couple of minutes, with no tools and no technician. Open the printer, lift the spent cartridge out, rock the new 1T02F90US0 gently side to side a few times so the toner inside spreads evenly, remove its protective strips, slide it in until it seats, and close the printer up. You can do it between one print job and the next.

The first few pages have come out pale. Is the cartridge faulty?

Almost certainly not. Toner powder settles during transit, so lift the cartridge out and rock it side to side again — the density usually comes back immediately. It is also worth checking that a toner-saving mode is not switched on in the print driver. If prints are still faint after both checks, contact us and the warranty will take care of it.

What protection and support come with it?

Every cartridge is backed by a 1-year warranty and 1-year free returns, with the details set out on our shipping & returns page. Your order ships from whichever of our warehouses in IL, PA, GA or CA is closest to you, and the support team answers Monday to Friday, 9 AM to 5 PM CST.

What should I do with the spent cartridge after fitting the new TK-322?

Hold onto it for a few days. If anything about the new cartridge's output looks wrong, the old unit — and the 1T02F90US0 code on its label — is your quickest reference for confirming you ordered correctly. Once the replacement is printing cleanly and the question is closed, the empty can leave with your office's usual recycling or waste; there is no need to keep it beyond that.

Can I keep a second TK-322 on hand so the FS-3900DN never waits?

Yes, and on a departmental printer it is a sensible habit. A factory-sealed cartridge keeps well for many months stored flat in a dry cupboard away from heat and sunlight, so buying the next 1T02F90US0 before the current one runs out costs nothing in print quality. When the toner message finally appears, the changeover is a two-minute swap instead of a stopped machine and a rush order.

Roughly when should I expect this cartridge to need replacing?

Work from your volume. The TK-322 is rated at 15,000 pages, so a workgroup printing about 1,500 pages a month will see something like ten months from it; double the volume and the span halves. Writing the install date on the box when you fit it makes the estimate real — at the halfway point of your expected span, order the next cartridge.

How do I tell a genuinely empty cartridge from one whose toner has just settled?

Use the rock test at the end of its life. Lift the cartridge out and rock it gently side to side: if density returns for a while, toner remained but had settled, and you have a short grace period rather than a finished cartridge. If prints stay pale straight after rocking, the 1T02F90US0 is truly spent and the correct move is to replace it, not to keep coaxing it.
