Okidata B4300N Toner | Compatible 42103001 Cartridges

B4300N

The B4300N is the network-equipped variant of the B4300 mono laser, made for shared office printing. Like the rest of the B4000 series it takes the 42103001 toner cartridge — one black cartridge serving every user on the network. Shared offices with heavier queues can step up to the high-yield 42102901, which keeps the machine running longer between replacements.

Networking changes the supply calculation. A personal printer's empty cartridge inconveniences one person; a shared printer's empty cartridge stalls a whole team. The B4300N therefore rewards the offices that treat toner as shared infrastructure — the longer-running cartridge, and a spare already in the building.

Which cartridge should you buy?

On a shared printer, the high-yield 42102901 is usually the right default: the queue is fed by several people, the page count climbs faster than anyone estimates, and every cartridge change is a pause for the whole office. The standard 42103001 still fits light-duty corners of the building where volume is low. Either way, hold one spare beyond the cartridge in the machine — with a networked printer, "we are out of toner" is a team announcement, not a private one. Compatible cartridges here are covered by a 1-year warranty and 1-year returns.

Chip, toner and everyday use

Because several workstations depend on this one machine, treat the low-toner warning as an action item rather than background noise: check the level when it first appears and make sure the spare is actually on site. Seat a new cartridge firmly until it clicks so its chip reports correctly to every user checking the queue. Store spares sealed until needed — an opened cartridge slowly degrades — and keep them near the printer, not in a storeroom across the building, so a changeover takes a minute.

Frequently Asked Questions

Which toner does the Oki B4300N use?

The 42103001 black toner cartridge, with the high-yield 42102901 as the longer-running option. It is a monochrome printer, so this single part number is the only toner you will ever need to stock for it.

Does the B4300N support network printing?

Yes — the "N" suffix marks a built-in network interface, so the printer is shared across the office over Ethernet. One cartridge serves every user on that network, which is why a networked mono printer stays cheap to run per page.

How do I extend the life of the cartridge in the B4300N?

Use the driver's toner-save or draft mode for internal documents, and shake the cartridge gently side to side when the low-toner warning first appears — that redistributes the remaining toner and often yields extra pages. Keep spare cartridges sealed until the day they are fitted.

Does the B4300N take the same cartridges as the B4300?

Yes. The network model shares the B4300's cartridge family exactly — the standard 42103001 and the high-yield 42102901 — so an office running both models stocks one shelf of supplies.
