Frequently Asked Questions

What do I actually receive in this 2-pack?

Two separately sealed compatible black toner cartridges, both carrying the 370AB011 part number and each rated at 34,000 pages. Because they are packaged individually, you can open one now and keep the second untouched until the machine asks for it.

Why do offices buy the pair instead of a single cartridge?

So a toner-out stoppage never waits on a delivery. One cartridge works in the copier while its twin sits on the shelf as an instant spare; when the first runs dry, the swap takes two minutes and you reorder at your leisure. At $185.12 the pair keeps a high-volume department moving without an emergency purchase.

How should the spare be stored while it waits?

Leave it sealed in its original packaging, flat, in a cool dry spot away from direct sunlight and heat vents. Stored that way it stays ready for many months, and its coverage starts whenever you finally open it — not from the day it was delivered.

Can I split the two cartridges between different machines?

Yes. Each unit is a complete, independent cartridge, so one can go into the KM-3035 down the hall while the other serves a KM-4035, or both can feed the same copier one after the other. Nothing ties them together once the outer box is open.

If one cartridge in the pair misbehaves, do I send both back?

No. Coverage is per unit: a faulty cartridge is handled on its own under the 1-year warranty and 1-year free returns, while the good unit keeps working in your machine. You never have to pull a healthy cartridge out of service to sort out a problem with its partner.

Is the changeover on these copiers a do-it-yourself job?

It is. Open the front panel, slide the empty unit out, slide the replacement in until it seats, and close up. No tools, no service call, and the machine returns to copying on its own in about two minutes.

How much printing does the pair cover in total?

Two 370AB011 cartridges at 34,000 pages each give you a 68,000-page pool from one $185.12 order. Spread across a department copier's counter, that pool translates into months of cover: check the machine's page counter monthly and the arithmetic tells you plainly whether a pair lasts your workgroup a quarter or half a year. Buying against that measured figure, instead of guessing, is what keeps the spare shelf neither bare nor overstocked.

What is the per-cartridge cost compared with buying singly?

Dividing the pack price by two puts each 370AB011 at $92.56, which works out to roughly 0.27 cents per rated page. The pair format trims the unit cost a little, but its bigger saving is operational: one order, one delivery and one invoice instead of two, plus the avoided cost of the emergency purchase that a bare shelf eventually forces. For a busy department, the avoided interruption is worth more than the arithmetic difference.

Why does the second cartridge sometimes seem to finish faster than the first?

Usually it has not — the work changed. The 34,000-page rating rests on standard text coverage, and a month of dense reports, heavy forms or graphics-rich documents draws noticeably more toner per sheet than a month of plain correspondence. If the copier's output mix shifted between the two cartridges, the second one's shorter life is coverage, not quality. Comparing page counters at each swap confirms it: similar pages per cartridge means consistent units, whatever the calendar says.

How should the two empties be handled over the pair's life?

One at a time, as each 370AB011 comes out: back into the box its replacement arrived in, then out through your site's toner recycling or disposal channel. There is no need to hold the first empty until the second is spent — the pair is not a set that travels together. The one habit worth keeping is to set aside, briefly, any empty that finished suspiciously early, until the cartridge that followed it has proven it prints cleanly.
