Frequently Asked Questions
How long will one 43,000-page black cartridge actually last in our office?
It depends entirely on your monthly volume. At 1,500 black pages a month, a single cartridge rated at 43,000 pages can run for well over two years. At 5,000 pages a month — a busy department pace — expect roughly eight to nine months. At a heavy 10,000 pages a month, you are looking at about four months per cartridge. The SP C840 is a workhorse-class machine, and this black cartridge is sized to match it, so most offices replace it a few times a year at most.
What does the printing cost work out to per page?
At $86.83 for a cartridge rated at 43,000 pages, the toner cost lands at about 0.20 cents per page. That is the arithmetic at the standard 5% coverage the rating is based on; dense pages with heavy black fill will use toner faster, and light text documents will stretch it further. Either way, this is a high-capacity cartridge, so the cost per page stays low compared with standard-yield options.
Will this cartridge work in my printer?
This black cartridge is made for Ricoh SP C840. Check your machine's model name against that platform: if your printer is an SP C840 series model, this is the black cartridge built for it. If you run a different Ricoh model, match the cartridge to the model printed on your machine rather than going by cartridge shape, since similar-looking cartridges are not interchangeable.
Should I keep a spare on the shelf, or order when the low-toner warning appears?
With a yield this high, the warning period alone gives most offices plenty of lead time to order. That said, if your SP C840 supports a department that cannot pause, a shelf spare removes the risk entirely. Sealed cartridges store well in a cool, dry place away from direct sunlight, so buying ahead does not waste anything.
What happens if the cartridge arrives damaged or prints poorly?
Every cartridge we sell is covered by a 1-year warranty, and returns are free for a full year as well. If this black cartridge arrives damaged, leaks, or produces streaky or faded output that a cleaning cycle does not fix, contact us and we will make it right under the terms on our shipping and returns page. Keep the cartridge and its packaging until the issue is resolved so we can help you faster.
Where does my order ship from, and how do I reach support?
Orders ship from whichever of our four warehouses — Illinois, Pennsylvania, Georgia, or California — gets the cartridge to you fastest. If you have a question before or after ordering, our support team is available Monday through Friday, 9 AM to 5 PM CST.
