Compatible high-yield toner four-pack

This set contains four LD Products 43502001 black cartridges rated at 7000 pages each under the ISO/IEC 5% coverage standard. They replace Okidata Type 9 originals for the B4550, B4600, B4550n, B4600n and B4600n PS printers purchased in the United States and Canada. Offices with consistent mono output will reduce per-page cost without changing workflow. Each cartridge is tested for reliable operation and bold, vivid text on every sheet.

Thermal and acoustic profile in daily use

Laser toner produces no liquid ink evaporation, so the printer maintains its normal operating temperature and noise level throughout a print run. The cartridges add no moving parts and draw no independent power, leaving the device's existing power profile unchanged. Users experience the same warm-up time and idle acoustics as with OEM supplies. Consistent density is maintained from the first page to the last of each 7000-page yield.

Behaviour under sustained high-volume printing

When the printer runs continuous mono jobs across all four cartridges, page yield remains at the rated 7000 pages per unit at 5% coverage. No fade or streak appears as the toner depletes because each cartridge is individually quality tested for long-lasting use. The regional firmware lock limits operation to hardware sold in the United States and Canada. Buyers with printers sourced outside those markets or who require colour output cannot use this pack.

Questions about this item

How do I install the 43502001 toner cartridge in my B4600 printer?

Open the front cover, pull out the old cartridge by its handle, shake the new cartridge gently side to side, remove the sealing tape, then slide it firmly into the same slot until it clicks.

What part will need replacement after the four 7000-page cartridges are used?

The separate drum unit in your B4550 or B4600 series printer will eventually reach its rated life and must be replaced independently of the toner supply.

What print-quality limit appears first during long, continuous print runs?

Toner density can fade once the cartridge overheats during extended high-volume printing, so allow cool-down periods between large jobs.
