Frequently Asked Questions

What does the second cartridge in this 2-pack actually save us?

Bought singly, two of these black cartridges would cost $97.00. This 2-pack is $78.50, so the pair saves $18.50 and brings the per-cartridge price down from $48.50 to $39.25. Across the pack's combined 18,000 rated pages, the per-page cost falls from about 0.54 cents to roughly 0.44 cents. Nothing about the cartridges changes — same Dell 310-5807 high-yield black, same 9,000-page rating each — you are simply paying less per unit for ordering the spare at the same time.

Why keep a spare black cartridge on the shelf at all?

Because a 5100 never announces its empty cartridge at a convenient moment. With the second unit already in the cupboard, a swap takes minutes and the workgroup never waits on a delivery. One cartridge works in the machine while the other waits — and the moment the spare goes in, you have a natural trigger to reorder, long before the printer can catch you short again.

How far does 18,000 pages stretch across a workgroup?

Combined, the pair is rated at 18,000 pages — around 36 reams of paper. A department printing 1,500 pages a month would be covered for roughly a year; a heavier floor at 3,000 pages a month gets about six months. Those figures assume standard 5% coverage, so graphics-heavy output shortens them, but as a stocking horizon the 2-pack suits most single-printer offices comfortably.

Will a cartridge stored for months still print properly?

Yes, provided it stays sealed in its packaging in a cool, dry place away from direct sunlight. Toner is a dry powder, not a liquid ink, so an unopened 310-5807 waits patiently on the shelf. Keep the box flat, use the older cartridge first, and the spare will perform exactly as the freshly delivered one did.

Are both cartridges the same specification?

They are — two identical compatible high-yield black cartridges, each Dell part number 310-5807, each rated at 9,000 pages, made for the Dell 5100 and 5100cn. There is no standard-fill unit hiding in the pack and no difference between the first cartridge and the second beyond which one you open first.

What cover do the cartridges come with?

Both units are protected by our 1-year warranty and 1-year free returns: if either fades early, streaks or fails, it comes back to us. Questions are answered by our support team Monday to Friday, 9 AM to 5 PM CST, and the full terms are on our shipping & returns page. Orders leave from warehouses in IL, PA, GA or CA, whichever holds stock closest to you.
