Frequently Asked Questions
Which codes should I check before ordering this single cartridge?
Look at the label of the cartridge coming out of your printer. You are in the right place when it shows either 1T02J00US0 or its companion designation, TK-342 — both identify this exact black toner cartridge for the FS-2020D. Matching either code is enough; they are two names for the same unit, not two different products.
How long will 12,000 pages actually last a small office?
The rating is measured at standard page coverage, and for a typical office FS-2020D turning out invoices, statements and correspondence it works out to many months of ordinary printing from this one TK-342. Heavy month-end billing runs shorten that stretch, quiet weeks lengthen it — but either way, a single cartridge is a long-lived supply, not something you will be reordering every few weeks.
Can I swap the cartridge in the middle of a print run?
Yes. Pause or let the current job finish, open the printer, lift the spent unit out and seat the new one — the queue on your computer is untouched, and printing resumes where it left off. Before fitting, take the fresh 1T02J00US0 out of its bag and rock it gently side to side a few times so the toner inside is evenly distributed, then remove any protective strips.
What arrives in the box?
A single factory-sealed black toner cartridge and nothing else to assemble. The cartridge is a complete unit: no separate parts, no add-ons to buy, and no tools needed at fitting time.
My first prints after the change look washed out. What fixes that?
Toner settles during shipping, so lift the cartridge out and rock it side to side again — output density usually recovers immediately. It is also worth checking that a toner-saving mode is not enabled in your print settings. If prints stay faint after both checks, contact us and we will resolve it under the warranty.
What cover and delivery service come with this purchase?
Every cartridge carries a 1-year warranty with 1-year free returns, as set out on our shipping & returns page. Orders leave from whichever of our IL, PA, GA or CA warehouses is closest to you, and help is available Monday to Friday, 9 AM to 5 PM CST.
Why might my cartridge finish well before 12,000 pages?
The 12,000-page rating for the 1T02J00US0 (TK-342) assumes standard test coverage — a modest amount of toner per page. Statements and letters sit close to that assumption, but pages carrying bold headings, shaded tables, logos or charts lay down far more toner and pull the real total down. Judge the cartridge against the kind of pages your FS-2020D actually produces, not the headline number alone.
When should I order the next cartridge?
At the first low-toner warning, not when output starts to fade. The warning arrives while a useful reserve is still in the TK-342, and ordering then — by the 1T02J00US0 or TK-342 code on the old cartridge's label — leaves a comfortable window for delivery from the nearest warehouse while the installed unit finishes its work.
Can I buy this cartridge ahead of time and keep it on the shelf?
Yes. Leave the 1T02J00US0 sealed in its bag, stored flat in a cool, dry cupboard away from sunlight and radiators, and it will wait patiently until the installed cartridge runs out. Toner is a dry powder, so a sealed spare does not dry out or go stale the way liquid ink can during storage.
What do I do with the old cartridge once the new one is in?
Slip the spent TK-342 into the bag and box the new cartridge came in — that keeps toner dust contained — and send it out through a local toner recycling route. Keep it for a few days first if the new unit has just gone in, so the old one is still on hand until the replacement has proven itself on real pages.
