Frequently Asked Questions
What does "up to 5,900 pages" actually mean for my printing?
It is a rating, not a promise counted page by page. The 106R03580 is rated for up to 5,900 pages at the industry-standard 5% page coverage — a typical text page. Dense pages, heavy graphics and bold headers drink toner faster, so a desk printing mostly contracts will land near the rating while a desk printing full-page forms will land under it. For most text-led offices, 5,900 is a fair planning number.
How do I know when it is really time to swap?
The low-toner warning is an estimate, not a deadline — it can appear with hundreds of pages still left in the cartridge. The reliable signal is the print itself: text turning grey or uneven, especially down one side, means the fill is genuinely spent. This listing puts one 106R03580 in your hand at $29.26, so waiting for the print to tell you, rather than the warning, costs you nothing.
Why buy a single cartridge instead of a pack?
Because one printer printing modest volume does not need a stockroom. A single 106R03580 covers up to 5,900 pages; if your Versalink B400 prints a few hundred pages a month, that is a year or more of printing from one box, with no cash tied up in spares and nothing aging on a shelf.
What should I do before the old cartridge comes out?
Very little. Have the new cartridge out of its box but still sealed until the moment of the swap, and keep the printer's front access clear. The change itself takes a couple of minutes: old cartridge out, new cartridge in, and the printer is ready. Bag the spent one straight away so loose toner dust stays off desks and hands.
Is this the same cartridge the B405 uses?
Yes — the 106R03580 serves both the B400 and the Versalink B405. Offices running one of each do not need two different spares on the shelf; this single listing covers either machine, which is why the part number, not the printer name, is the thing printed largest on the box.
What cover do I get with it?
The cover matches every cartridge we sell: a 1-year warranty and free returns for a full year, all of it set out on our shipping and returns page. Orders are dispatched from warehouses in IL, PA, GA and CA, support is staffed Monday through Friday, 9 AM to 5 PM CST, and more for this printer family sits on our Xerox toner page.
