Frequently Asked Questions
What does "Premium Quality" actually get me on this listing?
On this listing, honestly, no extra charge and no different cartridge. The Premium 5 pack is priced at exactly the same $335.50 as our standard TK-421 5 pack, and the cartridges inside carry the same 370AR011 / TK-421 codes and the same 15,000-page rating. We would rather say that plainly than dress the name up as a difference it is not.
So why does this listing exist alongside the standard 5 pack?
Because buyers search for it by this name. The two listings describe the same cartridge family and the same box quantity; the price is held the same on both, so choosing this one over the other costs you nothing and changes nothing about what arrives.
Is the page yield any higher because of the Premium label?
No. Each cartridge in this pack is rated at 15,000 pages — the same rating as every other TK-421 unit we sell for the KM-2550. The label does not stretch the rating, and we do not claim otherwise anywhere on this page.
Does the Premium name change the warranty or returns position?
It changes nothing in either direction. This pack carries the same 1-year warranty and 1-year free returns as the standard listing, applied cartridge by cartridge. A unit that fails is handled exactly the same way whichever of the two listings it came from.
What arrives in the box?
Five individually sealed black cartridges, each printed with the 370AR011 / TK-421 code pair. Count them on delivery and check for transit damage before shelving; anything crushed or unsealed should be reported to us straight away so it can be put right.
Who should pick this listing, and who should pick the other one?
It genuinely does not matter — pick whichever you found first. Same cartridges, same quantity, same $335.50. If your purchasing system already has one of the two listings saved, there is no reason to switch it.
Does the running cost on this Premium pack differ from the standard five-pack?
No, and the arithmetic is identical because everything else is: $335.50 across five 370AR011 / TK-421 cartridges is $67.10 a unit, and 75,000 rated pages puts the cost at roughly 0.45 cents per page. The Premium name adds nothing to the price and nothing to the cost per page — the two listings land on exactly the same numbers, whichever one your ordering system holds.
At our volume, how long will the pack's 75,000 pages actually last?
It is simple division. A KM-2550 copying 2,500 pages a month takes about thirty months to work through five cartridges; at 5,000 pages a month the same box lasts roughly fifteen months; a very busy room at 7,500 a month is through it in ten. Find your machine's monthly figure on its counter and the pack converts straight into a calendar you can plan purchases around.
The fifth cartridge may sit sealed for well over a year — will it still print properly?
Yes, provided it waits in sensible conditions: sealed in its box, indoors at normal room temperature, away from damp and direct heat. Toner is a dry powder and does not dry out in storage, so a TK-421 opened in month eighteen behaves like one opened in month one. Before fitting a long-shelved unit, a gentle side-to-side rock levels the settled powder for even first pages.
Could this stock serve a second KM-2550 if we add one later?
Yes. The pack is defined by the 370AR011 / TK-421 code pair, not by the machine you bought it for, so any copier whose supply list calls for that cartridge can draw from the same shelf stock. If a second KM-2550 arrives next year, the sealed units transfer to it without any change of ordering — one shared reserve simply feeds both machines.
