C3100n
The Okidata C3100n is a networked color laser printer from OKI's compact C3100 line, suited to small offices that need everyday color on a shared network. It is listed with the Type C6 toner family: the 43034804 black cartridge and the 43034801, 43034802 and 43034803 color cartridges. Before ordering, it is worth matching the number on the cartridge already installed — the four numbers in this family differ only in their last digit.
Sharing changes how a small printer uses toner. A C3100n serving several desks prints other people's color as readily as your own, and the machine also spends small amounts of color toner on calibration and registration cycles even while producing black-and-white pages. Neither is a fault; both mean the networked model deserves an occasional glance at its levels rather than a surprise when a colleague's presentation comes out missing its blues.
Toner Cartridges for C3100n
| Cartridge | Color | Page Yield |
|---|---|---|
| 43034803 | Cyan — listing 1 of 2 on this page | See product page |
| 43034803 | Cyan — listing 2 of 2 on this page | See product page |
Type C6 reference numbers: yellow 43034801, magenta 43034802, cyan 43034803, black 43034804. The cyan is the cartridge stocked on this page, in two listings of the same supply.
Which cartridge should you buy?
Buy the number the printer names. When a C3100n reports its cyan low, the replacement is the 43034803 stocked here — the two listings on this page are the same cartridge, so either listing restocks the correct channel. Resist the urge to order a color you might need soon; on a shared printer, levels move at their own pace, and a cartridge bought early for the wrong channel helps nobody. If the office relies on this machine daily, the one spare worth shelf space is the color your documents use most — for most small offices running charts and branded documents, that is cyan or black.
Chip, toner and everyday use
A note on what the C3100n actually is: despite often being called a laser printer, it is a digital LED design, like the rest of Oki's C series — the practical difference for a buyer is minimal, since the toner cartridges are bought the same way, and LED models tend to be more compact than equivalent laser designs. For everyday care, keep the driver default honest: if color levels fall during what should be mono printing, check that the default is truly black-and-white and not auto color, which engages the color cartridges on any page containing a single colored element, such as a blue hyperlink in an email printout.
Frequently Asked Questions
What toner does the Oki C3100n use?
Yellow 43034801, magenta 43034802, cyan 43034803 and black 43034804 — the Type C6 family it shares with the C3100. The added n in the model name is the network connection.
Is the C3100n a laser printer?
Strictly, no — it is a digital LED printer. For supply buying nothing changes: you still order the 43034801–43034804 cartridges, one color at a time.
Why does my C3100n use color toner on black-and-white pages?
Calibration and color registration cycles consume small amounts from the color cartridges even during mono work. If levels drop quickly, the likelier cause is a driver left on auto color rather than the calibration — check the default setting first.
The blues from my C3100n look washed out. Which cartridge is responsible?
Cyan — part number 43034803, the cartridge stocked on this page. Faded blues with strong reds and yellows are the signature of a cyan channel running dry.
