Frequently Asked Questions

Which four cartridges arrive in this set?

One of each color the machine runs on: TK8507K in black, TK8507C in cyan, TK8507M in magenta and TK8507Y in yellow. It is a complete four-cartridge refresh in a single order, so all four stations in the copier can be renewed together rather than one at a time over several weeks.

How much printing does each cartridge in the set cover?

The black TK8507K is rated at 30,000 pages, and each of the three color cartridges — cyan, magenta and yellow — is rated at 20,000 pages. Those are standard test-page ratings, so a department printing mostly text with light color will see the colors last considerably longer than the rating suggests, while heavy full-color work will use them faster.

Which machines does this four-color set feed?

It is built for the TASKalfa 4550ci, and the same TK8507 family also serves the TASKalfa 4551ci and TASKalfa 5550ci. If your fleet mixes those models, one set type covers all of them, which keeps the supply shelf simple.

Do all four cartridges have to go in at the same time?

No. Each cartridge is sealed on its own, so you can install only the color the machine is asking for and keep the rest on the shelf. Many offices fit the full set when several colors are low together, then replace individually after that. Unopened cartridges store well in a cool, dry cupboard away from direct sunlight.

What should the first color prints look like after a full set change?

Clean and even. If one color band looks weak on the first pages, remove that cartridge, rock it gently side to side to redistribute the toner, and reseat it. Still uneven after a short test run? Contact us while the set is still near full so we can help.

What cover comes with this set?

Every cartridge in the set is backed by a 1-year warranty and 1-year free returns. Support is available Monday through Friday, 9 AM to 5 PM CST if anything arrives damaged or underperforms early.

What should I check when the four-color set arrives?

Before anything goes near the machine, match the four boxes against the four slots: TK8507K for black, TK8507C for cyan, TK8507M for magenta and TK8507Y for yellow, with every seal intact. A set is a bigger box to receive than a single cartridge, and two minutes at the delivery bench — counting four units, reading four codes, checking for transit damage — is what stops a wrong or damaged cartridge being discovered weeks later, mid-change, when the machine is already waiting.

If two slots run low in the same week, which cartridge goes in first?

The one the machine has actually stopped or warned on first. There is no technical order the four cartridges of this set must follow, and no benefit in changing a slot that still has working toner in it. Fit the TK8507 cartridge the copier is asking for, leave the others sealed on the shelf, and let each remaining unit wait for its own warning — the set is drawn down one slot at a time, exactly as if the cartridges had been bought individually.

How do I learn how fast each color is really being used?

Keep a short change log on the supply shelf: date, slot and cartridge code each time one of the set goes in. One full round of the TK8507 family is enough for patterns to show — which color your department genuinely burns through, which one lingers, and whether the black's 30,000-page rating really does outlast the colors' 20,000 in your mix. That record turns the next order from a guess into a decision about whether a full set or a single cartridge is the right buy.

How much printing does the whole set represent?

Adding the ratings together: 30,000 pages from the black plus 20,000 pages from each of the three colors gives 90,000 rated pages across the four TK8507 cartridges, all at standard coverage. In practice the colors will not empty together — black typically cycles ahead of them on document work — so read the total as the size of the supply pool you have bought, drawn down at four different rates, rather than as a single countdown.
