Frequently Asked Questions
What exactly does the number 106R03580 identify?
It is the part number of the standard-capacity black toner cartridge for two Xerox printers: the Versalink B400 and the Versalink B405. This listing is the part-number route to that cartridge — one single 106R03580, rated for up to 5,900 pages, sold under the number printed on the cartridge you are taking out.
How does the cost per page work out?
At $29.26 for up to 5,900 pages, the toner cost lands at about half a cent per page. That is the number worth keeping for any budget comparison: every page off your B400 costs roughly $0.005 in toner, and there is no smaller, pricier fill quietly pushing the figure up between cartridge changes.
How long will 5,900 pages last in a real office?
Measure it against your own volume. At roughly 300 pages a month, one cartridge carries you well over a year and a half; at 500 pages a month, about a year; a busier desk printing 1,000 pages a month will see around six months. Either way, this is a swap you make a couple of times a year at most, not a monthly errand.
What arrives when I order this listing?
One cartridge. The name carries no pack count because there is none to count — a single sealed 106R03580, ready to slot in. Buyers who want a shelf spare as well as the working cartridge will find the same cartridge bundled in the multi-packs elsewhere on this page's family, but this listing stays deliberately simple: one cartridge, one swap, done.
Can I keep one on the shelf as a spare?
Yes, and for a printer in daily use it is the sensible default. Keep the spare sealed in its bag, stored flat at normal room temperature, away from direct heat and sunlight, and fit it only when the installed cartridge is spent. A sealed spare turns a toner-out stoppage into a two-minute swap instead of a lost afternoon.
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 Cartridge
This is the anchor listing for the family: a single compatible 106R03580 black cartridge at $29.26, rated for up to 5,900 pages. It is the one buyers reach for when the spent cartridge is already in their hand and the number on its label is the surest search they have — one swap, about half a cent of toner per page, and the B400 goes back to work.
