Frequently Asked Questions

Why does this listing come as two cartridges instead of one?

Because on a busy color TASKalfa, black is almost always the first supply to run out — the color cartridges keep going while the black is empty. This 2 pack of TK8507K cartridges puts one in the machine and one on the shelf, so the next low-toner warning is a quick swap instead of a stalled print queue. The pair sells for $230.98.

How do I confirm TK8507K is the number my machine takes?

Pull the black cartridge that is in the printer now and read its label, or open the machine's supply status page — the black toner is listed there as TK8507K. This pack is built for the TASKalfa 4550ci, TASKalfa 4551ci and TASKalfa 5550ci.

Can the two cartridges be split between two different printers?

Yes. The 4550ci, 4551ci and 5550ci all draw from the same black cartridge, so one pack can feed two machines on the same floor. Many offices keep the spare next to whichever printer does the heavier reporting work and move it if the other machine empties first.

What does a single cartridge in this pack deliver?

Each TK8507K is rated at 30,000 pages of black output under standard test coverage. Dense pages — financial statements with heavy tables, bold headers, shaded forms — will land below that figure, while plain correspondence tends to track close to it.

How should the spare cartridge be stored?

Sealed, flat, and out of direct sunlight in a normal office environment. Toner does not dry out the way ink does, so a cartridge bought in this pack today is still ready to install months later when the first one runs down.

What protection and delivery come with the pack?

Both cartridges carry a 1-year warranty and 1-year free returns. Orders ship from our warehouses in IL, PA, GA and CA, and support answers Monday through Friday, 9 AM to 5 PM CST — see the shipping and returns page for timing and return steps.

What does each cartridge in this two-pack work out to?

The pair is $230.98, so each TK8507K in it costs $115.49 — less per cartridge than buying the black one at a time — and at the 30,000-page rating that is roughly 0.38 cents per page at standard coverage. Pages heavy with tables, bold headers and shaded forms will sit above that figure and plain correspondence below it, but for a department costing its black supply across a quarter, the two-pack's per-cartridge figure is the one to budget with.

When should the next two-pack be ordered?

The day the shelf spare goes into the machine. This pack is built as one working cartridge plus one sealed reserve, so the moment the reserve is fitted, the cover it provided is gone and the replacement order should be raised while a full TK8507K is still running. Ordering on that trigger — rather than when the fitted cartridge later runs low — keeps the two-minute swap available every time, which is the entire point of holding the pair.

How can the first cartridge tell me when the second will run out?

Note the page counter when the first TK8507K goes in and again when it comes out; that difference is your machine's measured life for this black under your real coverage. Apply the same figure to the second cartridge and you have a close forecast of its change date, accurate enough to diary the next order. If the second cartridge empties far earlier than the forecast, the document mix has changed — more graphics, more solid fills — rather than the cartridge being at fault.

How should the two empty cartridges be handled?

Keep each spent TK8507K until its replacement has printed cleanly for a few days, so that if a unit ever misbehaves early, it can be dealt with on its own under the 1-year warranty and 1-year free returns. Beyond that, the pair's empties need nothing special: box them so toner residue stays contained and send them out with your office's normal used-cartridge disposal, together or one at a time as they come out of the machine.
