Quick Answer: The OKI B412dn uses black toner cartridges with part numbers 45807101 (3,000 pages) or 45807105 (7,000 pages). Both fit the same slot – you’re simply choosing between capacity and upfront cost. The high-yield version typically works out around 35% cheaper per page.

Which OKI B412 Toner Do You Need?

OKI keeps things straightforward with the B412 series. There’s one toner colour (black, obviously – it’s a mono printer) and two capacity choices. The cartridge design is identical for both, so swapping between them is seamless.

Breaking Down the Numbers

Page yields are calculated using ISO/IEC 19752 standards – basically, 5% coverage on an A4 page. Real-world results depend on what you’re actually printing. Heavy graphics or dense text? You’ll use more toner. Simple letters and invoices? You might exceed the stated yield.

Worth Knowing: The B412dn ships with a 2,000-page starter cartridge, not the full 3,000-page standard version. Budget for a replacement sooner than you might expect if you’re setting up a new printer.

Cost Per Page Comparison

Cartridge	Part Number	Page Yield	Best For
Standard Yield	45807101	3,000 pages	Light use, lower upfront cost
High Yield	45807105	7,000 pages	Regular printing, best value per page

Here’s a scenario that comes up often: you’re printing around 1,000 pages monthly. With the standard cartridge, you’d replace it roughly every three months. Switch to high yield, and you’re looking at seven months between changes. Fewer interruptions, less hassle, better value.

Compatible Printers

These OKI B412 toner cartridges work across several printer models in the B4xx and B5xx series. It’s a shared platform, which is actually quite handy if you’re running mixed OKI hardware.

OKI’s digital LED technology is the quiet hero here. Fewer moving parts than traditional laser means better reliability and consistent quality across the toner cartridge’s entire lifespan.

Getting the Most from Your OKI B412 Toner

Storage Tips

Unopened OKI B412 toner cartridges store well for around two years. Keep them sealed in their original packaging, away from direct sunlight, in a room that doesn’t swing between temperature extremes.

When to Replace

The B412dn gives you fair warning before toner runs out. You’ll see a “Toner Low” message with roughly 10% remaining – enough time to order a replacement without panic.

Troubleshooting

Noticing faded prints? Before assuming it’s the toner, check the drum unit (part 44574302). Worn drums often get blamed on toner cartridges.

Pro Tip: Remove new cartridges from packaging and rock them gently side-to-side before installation. This redistributes the toner evenly and ensures consistent density from your first print.

Why Genuine OKI B412 Toner?

Compatible cartridges exist, and they’re tempting on price. But here’s what you’re actually weighing up:

Warranty protection: Third-party toner can void your OKI warranty if something goes wrong
Consistent yields: Genuine cartridges hit their stated page counts reliably
Print quality: OKI’s toner formulation is matched to the fuser temperature and drum coating
No gamble: Compatible quality varies wildly between batches and suppliers

We’ve seen plenty of printers come through with toner leaks, fuser contamination, and drum damage traced back to cheap refills. The initial saving rarely covers the repair bill.
