Frequently Asked Questions

What does a ten-pack buy beyond the lowest per-cartridge price?

Supply security at department scale. Ten ML-D4550B cartridges hold 200,000 rated pages — enough that toner stops appearing on anyone's problem list for a very long stretch. The price step is real, but the larger purchase is continuity: no emergency orders, no printer standing idle waiting for a delivery, no mid-run surprises.

What are the numbers at this size?

The ten-pack is $899.28: $89.93 a cartridge, roughly 0.45 cents a page across 200,000 pages. Set against ten singles at $106.57 — $1,065.70 in total — the box saves $166.42, the largest single saving in this family.

Who should walk past this pack and buy smaller?

Anyone whose printing is light or shrinking. The warranty year starts at purchase, and cartridges nine and ten in a slow office could sit sealed well beyond it. If a year's volume is two or three cartridges, the three-pack is the honest buy; this pack earns its place where weekly volume is measured in reams.

Which printers will draw from the box?

All ten cartridges are the ML-D4550B supply listed for the ML-4050, ML-4050N, ML-4550, ML-4551N and ML-4551ND. A facilities cupboard holding this pack can serve every one of those models from a single stock line.

How should ten cartridges be stored and rotated?

Sealed, boxed, flat and dry — and drawn strictly in arrival order. Toner is patient, but rotation keeps the oldest unit next in line and the stock honest. A simple count on the shelf, checked monthly, tells you when the box is running down long before the last cartridge is fitted.

What protection covers an order of this size?

The same as any order here: a one-year warranty on each cartridge and free returns throughout the first year, set out on the shipping and returns page. Support is available Monday to Friday, 9 AM to 5 PM CST if anything about the supply needs sorting out.
