C831
The Okidata C831 is a color laser printer designed around high-capacity cartridges, which makes it a strong fit for offices that print serious color volume. Its cartridge set is 44844512 in black, 44844511 in cyan, 44844510 in magenta and 44844509 in yellow — and every one of the four is rated at 10,000 pages. That capacity is the point of this machine: long runs between cartridge changes, even when color work is heavy.
A 10,000-page rating changes how an office plans its supplies. Instead of a cartridge rhythm measured in weeks, the C831 asks for attention a few times a year, and the practical question becomes which single color is draining fastest in your particular mix of documents. Graphics-heavy teams may lean on one color; offices printing mostly text with color accents will watch black and one accent color do most of the work. Either way, the four positions are independent, and the printer tells you which one is getting low long before it stops you.

Which cartridge should you buy?
Order the single cartridge for the color that is running out — at 10,000 pages per cartridge, replacing a position early wastes more toner than on a smaller machine. The full sets make sense in two situations: setting up a C831 that is new to you, so all four positions start fresh together, or restocking when several colors happen to be low in the same period. Two set listings are stocked here, a standard 4 Color Set and a premium-quality 4 Color Set, alongside the model-named set; any of them covers all four positions in a single order. Whichever route you take, every compatible cartridge on this page is backed by a 1-year warranty and 1-year returns.
Chip, toner and everyday use
A toner-low warning on the C831 is an early heads-up, not a stop signal — pages usually keep looking good for some time after it appears. A gentle shake of the cartridge, side to side with the printer off, redistributes the toner and buys extra pages while the replacement is on its way; order the spare when the warning first shows and you will never be caught mid-job. If thin white lines appear across color areas, dust on an LED printhead lens is a common cause: power the machine off and wipe each lens with a soft, dry, lint-free cloth, without touching the lens with bare fingers.
Frequently Asked Questions
What toner cartridges does the C831 use?
The C831 takes yellow 44844509, magenta 44844510, cyan 44844511 and black 44844512, each rated at 10,000 pages. Since each color loads separately, you only ever replace the one that is empty.
My C831 warns toner is low but pages still look good — can I keep printing?
Yes. The warning arrives early by design, and gently shaking the cartridge buys additional pages. Treat it as your cue to order the replacement for that color so the spare is on the shelf when print quality actually starts to drop.
My C831 prints thin white lines — could dirty LED heads be the cause?
Yes, that is a likely cause. Dust on an LED lens blocks light and leaves white streaks in that color's areas. Power the printer off first, then wipe each lens gently with a soft, dry, lint-free cloth and print a test page to check the result.
Do all four cartridges really last 10,000 pages?
Each of the four is rated at 10,000 pages, but ratings assume standard page coverage, so a color used heavily in dense graphics will finish sooner than one used for occasional accents. In practice the positions run out at different times, which is exactly why they are replaced one at a time.
