Frequently Asked Questions

We budget office supplies quarterly — how does this three-pack fit that rhythm?

Neatly, for an ML-1640 in steady use. The pack holds 4,500 rated pages; a small office printing around 350 to 400 pages a month will find three cartridges roughly a quarter's supply, so one line on the quarter's budget covers toner until the next one. Heavier use shortens the span and lighter use stretches it, but the pack's size is aimed squarely at that buy-it-and-forget-it quarterly pattern.

What does each cartridge in the three-pack effectively cost?

$37.19. The pack is $111.58 against $49.52 for the single MLT-D108S, so the three bought this way save $36.98 compared with three separate single orders, and the per-page cost falls to about 2.48 cents from roughly 3.3 cents. The cartridges are identical to the single; the improvement is purely in the buying.

Do all three cartridges carry the ML-1640's code?

Yes — every unit is the MLT-D108S named in the listing title, the same supply behind the ML-2240 and ML-2241 listings in this family. An office running the ML-1640 alongside one of those siblings can treat this pack as shared stock, since the code, not the badge, decides what fits.

How should the three cartridges be rotated?

In arrival order. Keep them sealed, flat and dry; fit the longest-waiting box first when the printer calls. With three units the rotation manages itself, and the practical benefit is visibility: one cartridge in the machine, one on the shelf and one fitted recently tells you at a glance where you stand in the quarter's supply.

What cover applies across the pack?

A one-year warranty against defects on each cartridge, and free returns for a full year on the purchase — the terms are laid out on our shipping and returns page. If any one of the three misbehaves, it is handled on its own; the rest of the pack is unaffected.

Does the pack ship as one parcel?

It does — one box from the nearest of our IL, PA, GA and CA warehouses, and our support team is available Monday to Friday, 9 AM to 5 PM CST. One dispatch also means one delivery to plan around, rather than three separate arrivals scattered across the months.
