B4600

The B4600 anchors the upper end of OKI's B4400-generation mono laser family, built for busy offices that ask a lot of a black-and-white printer. Its toner choice mirrors the rest of the family: the 43502301 standard cartridge at 3,000 pages, or the 43502001 high-yield cartridge at 7,000 pages for desks that print in real volume. The toner works against a separate drum unit, the 43501901, which typically lasts through several cartridges — around 25,000 pages — before it needs replacing.

Sitting at the top of its generation means the B4600 usually inherits the heaviest queue in the office: the end-of-month reporting run, the shipping documents, the forms everyone else routes to the sturdy machine down the hall. That workload profile is exactly what a two-tier cartridge system is for. Standard fills keep a lightly loaded machine cheap to feed; the high-yield cartridge exists so the busiest printer in the building is also the one interrupted least often by an empty toner light.

Toner Cartridges for B4600

Drum unit, sold separately:

• 43501901 — Black, about 25,000 pages. Multi-packs of the same drum are sold on this page under B4400 drum listings.

The two toner cartridges also appear on this page under B4400 listings, in counts from single to 10 packs — identical cartridges, shared across the family.

Which cartridge should you buy?

On the family's hardest-working printer, the high-yield 43502001 is the default recommendation: 7,000 pages per change keeps a busy queue moving, and the per-page cost undercuts the standard fill. The standard 43502301 still suits a B4600 that has been moved to a quieter role, where a smaller fill avoids parking money in a slow machine. Multi-packs belong in the same conversation as the yield choice — a 5 or 10-count of the high-yield cartridge turns a year of heavy printing into a single purchase. And keep the two consumables separate in your budget: toner is routine, the drum is a rare event roughly every third or fourth high-yield cartridge.

Chip, toner and everyday use

Learn this printer's two failure accents and you will rarely guess wrong. Vertical streaks that repeat at regular intervals down every page are a worn drum announcing itself — check the drum life on the status page before touching the toner. Overall fading or random light print, by contrast, is the toner running low; rock the cartridge gently to level out what remains and order its successor. Heavy cardstock and labels belong in the manual or multipurpose tray with the matching media type selected, because the wrong setting leaves toner unfused and rubbing off the sheet. Ratings assume 5% coverage; report-heavy months will run shorter.

Frequently Asked Questions

What consumables does the OKI B4600 use?

The 43502301 standard toner at 3,000 pages, the 43502001 high-yield toner at 7,000 pages, and the 43501901 image drum at around 25,000 pages. Toner and drum are separate replaceable units — you replace whichever one is actually worn instead of discarding a combined unit.

My B4600 prints vertical streaks down every page. Toner or drum?

Almost certainly the drum. Streaks repeating at regular intervals are the classic worn-drum symptom, so check the 43501901 drum's life counter first. Random light print or general fading, on the other hand, points to toner running low.

Can the B4600 handle heavy cardstock or labels?

Yes, within its rated media weights. Feed heavy stock through the manual or multipurpose tray and select the matching media type in the driver so the fuser applies the correct heat — wrong media settings are what leave toner rubbing off the page.
