Frequently Asked Questions
What toner fits the Oki C3100?
The C3100 uses black 43034801, cyan 43034802, magenta 43034803 and yellow 43034804. It is an entry-level color LED printer, and the four cartridges install individually.
Is the C3100 expensive to run for a home office?
It is reasonable if you manage color use: default the driver to black-and-white so daily printing consumes only the 43034801 black cartridge. The separate-cartridge design means you are not paying for color toner on monochrome pages — the main cost trap on small color printers.
My C3100 prints blank pages — is the toner empty?
Blank pages with toner still in the cartridges usually point to something else: check that the protective tape was removed from each 43034801–43034804 cartridge and that the cartridges are fully seated. If a new cartridge prints blank, the LED printhead cable or a dislodged drum is more likely than four simultaneous toner failures.
