Frequently Asked Questions
Our printer runs all day — how long will one 10,300-page cartridge actually last us?
Translate the rating into paper: 10,300 pages is a little over twenty reams. An office printing 1,000 pages a month will take roughly ten months to spend this cartridge; at 3,000 pages a month it lasts about three and a half months; a genuinely busy workgroup at 5,000 pages a month will finish it in around two. The rating assumes the standard 5% page coverage, which ordinary letters, invoices and reports roughly match — so for a black-only workhorse like this one, the rated count is a fair planning number rather than a best-case fantasy.
What does a printed page cost with this cartridge?
Divide the price by the yield: $41.65 across 10,300 rated pages works out to about 0.40 cents per page — four-tenths of a cent of toner on every sheet. Dense pages spend more than that, because a page of bold contracts or full-page forms lays down several times the toner of a short memo; light correspondence spends less. Averaged across a normal office mix, though, the 0.40-cent figure is the honest yardstick for what this cartridge does to your cost per page.
The printer says toner is low. Is the cartridge finished?
No — the low warning is a planning signal, not a verdict. It appears while there is still useful toner inside, precisely so a busy office has time to arrange the replacement before print quality becomes the messenger. The real end announces itself on paper: text that fades down the page, gray patches where solid black should be, density that varies from the top of the sheet to the bottom. Gently rocking a fading cartridge side to side can redistribute what is left and buy a short reprieve, but treat that as the final warning — when a single 106R03940 is your only cartridge, the low message is the moment to order.
The cartridge I pulled out has a long code on its label. How do I confirm this is the same one?
Read the code, not the printer's marketing name. 106R03940 is this cartridge's complete identity — black toner, this yield class, this machine family — and if the label on your empty unit reads 106R03940, this is its match. The same cartridge serves the Versalink B600, Versalink B605, Versalink B605 SL, Versalink B605 XL, Versalink B610, Versalink B615 SL and Versalink B615 XL, which is why several different printers on the same floor can all point you back to this one listing.
What should I check on the first pages after fitting it?
Fitting takes no tools and no settings — the new cartridge seats where the old one sat. Your first test is a dense page: a bold heading, a solid black block, anything that would expose weak coverage. It should come out evenly black from edge to edge, with no pale band down one side and no repeating marks. If the first sheet looks washed out, the usual culprit is a piece of packing or the protective seal still in place — pull the cartridge, check, and reseat it before suspecting the toner itself.
What stands behind this cartridge if something goes wrong?
Every cartridge we sell carries a one-year warranty, and returns are free for that entire year — a unit that leaks, arrives damaged, or simply fails to print as it should comes back to us at no cost to you. Orders ship from our warehouses in IL, PA, GA and CA; the full terms live on our shipping and returns page. If you want a person rather than a page, support is available Monday through Friday, 9 AM to 5 PM CST.
About This 106R03940 Black Toner Cartridge
This Clever Supplies compatible black cartridge replaces the Xerox 106R03940 — a single cartridge rated at 10,300 pages and priced at $41.65, roughly 0.40 cents per rated page. It is built for the rhythm of a monochrome workgroup machine: one unit in the printer, months of ordinary office output, and a low-toner warning that arrives in time to plan the next one. Nothing about the swap is exotic; the specification that matters is the code on your empty cartridge, and when that code reads 106R03940, this is the same color, the same yield class and the same fit, ready to install.
