Frequently Asked Questions
What do I actually get in this 2 pack?
Two 106R03580 black toner cartridges, each rated for up to 5,900 pages — 11,800 pages of printing in the box, for the Versalink B400 and its multifunction sibling, the Versalink B405. Both cartridges are the identical part number, individually sealed, so the second waits in its bag until the day the first runs dry.
What does each cartridge cost inside the pack?
$20.00 apiece. The pack is $40.01 for two, against $29.26 for the single cartridge bought on its own — so the pair saves you $18.51 compared with buying the same two cartridges one at a time. Nothing about the cartridge changes; only the unit price does.
How does the cost per page work out across the pair?
Across 11,800 rated pages, $40.01 works out at roughly a third of a cent per page — about 0.34 cents. That is the real economy of this pack: the working cartridge prints at the lower rate from day one, instead of you paying single-cartridge prices while you wait to see whether a spare was worth it.
One in the printer, one on the shelf — is that the idea?
Exactly that. Fit the first cartridge now and keep the second sealed, flat, at room temperature, away from heat and sunlight. When the installed cartridge fades, the swap takes two minutes and the printer never sits idle waiting on a delivery. For a single-printer office, one working cartridge plus one sealed spare is the setup that quietly prevents the toner-out emergency.
How long will 11,800 pages last us?
At about 500 pages a month, close to two years. At 1,000 pages a month, roughly a year. Even a heavy desk at 2,000 pages a month gets about six months out of the pair. Whichever way your volume falls, ordering becomes a rare, planned event rather than a reaction to pale print.
What cover do I get with it?
Every cartridge we sell carries a 1-year warranty with free returns for a full year, set out on our shipping and returns page. Orders leave warehouses in IL, PA, GA and CA, support answers Monday through Friday, 9 AM to 5 PM CST, and the wider range for this printer family lives on our Xerox toner page.
About This 106R03580 2 Pack
This is the working-plus-spare listing for the family: two compatible 106R03580 black cartridges at $40.01, $20.00 a cartridge, good for up to 11,800 pages between them. It is sized for the office that prints every day and cannot afford a dead printer — one cartridge earning its keep in the machine, one sealed on the shelf, and a per-page cost of about a third of a cent while both of them last.
