Frequently Asked Questions

The cartridge I removed is stamped ML-D4550B — is this the same supply?

Yes. The code moulded into the cartridge you took out is its identity, and ML-D4550B is precisely the cartridge this listing sells, in compatible form. Ordering against the code rather than the printer model is the surest way to reorder, because this one unit serves five different machines in the range.

What does a 20,000-page rating mean for a busy department printer?

It means long stretches of unattended printing between changes. Rated at 20,000 pages, the ML-D4550B is the high-yield option for this platform: a department machine turning out a few hundred pages a day measures this cartridge's life in months, not weeks. The rating assumes the standard measure of about 5% coverage, so dense reports and heavy graphics will spend it faster.

What does one page work out to?

At $106.57 across 20,000 rated pages, the toner runs at about 0.53 cents a page. That per-page figure is the honest way to judge a cartridge in this price band: the shelf price is substantial because the page count behind it is substantial too, and the two numbers belong together.

Which printers does this cartridge serve?

The ML-D4550B is listed for the ML-4050, ML-4050N, ML-4550, ML-4551N and ML-4551ND. Departments running more than one of those models can hold a single spare on the shelf and know it will fit whichever printer asks first.

We have been buying the standard ML-D4550A — can we change over?

Yes, and nothing on the printer needs adjusting. The ML-D4550A and this ML-D4550B are siblings for the same machines; the B code is simply the larger fill, so the change buys a longer interval before the next swap rather than a different kind of supply.

What cover stands behind a compatible cartridge at this price?

Every unit carries a one-year warranty against defects, and the purchase can be returned free of charge at any point within that first year — the full terms sit on our shipping and returns page. Support is available Monday to Friday, 9 AM to 5 PM CST.
