Frequently Asked Questions

Why does a stockroom keep five of one cartridge on a single shelf line?

Because a Dell 1100 that stops mid-task costs more in lost time than toner ever does. Five 310-6640 cartridges on one labeled line means the printer is never the reason a job waits: whoever finds it faded fits the next unit and the shelf still holds stock. For a machine in daily service, five is not excess — it is the buffer that makes toner a background concern instead of a recurring errand.

What does stocking by the number 310-6640 prevent?

The classic supplies error: a shelf of near-identical black cartridges, half of them for printers the office no longer has. One part number on the shelf line, matched to one number on the purchase order, keeps the 1100's stock pure. When a cartridge is issued, it is the right one by construction, not by somebody's memory of which box looked familiar.

What is the per-unit cost for inventory purposes?

$24.19 per cartridge — $120.97 for the five — against $38.99 at the single price, a saving of $73.98 across the pack. At the rated 2,000 pages per cartridge that is about 1.21 cents per page, the figure to use if the office allocates print costs. The units are the same compatible 310-6640 cartridges sold singly; the pack simply prices them as stock.

What reorder rule works with a 5-pack?

Reorder when the shelf drops to two. That leaves one working spare while the next pack is in transit, and it converts purchasing from a reaction into a rhythm: fit a cartridge, count the shelf, order at two. At typical small-office consumption the cycle runs a few times a year, each order a single line — 310-6640, quantity one pack.

How are the five cartridges rotated?

Oldest first, without exception. Date each box on arrival, issue from the front, and never open a fresh box while an older one waits. Sealed toner stores well, but rotation keeps the stock honest: no cartridge ages forgotten at the back of the cupboard, and the count on the shelf always means what it says.

If one unit in the pack fails, what then?

It goes back on its own. Every cartridge in the pack carries an individual 1-year warranty and 1-year free returns — the full terms are on our shipping & returns page — so a single bad unit never unravels the whole purchase. Support runs Monday to Friday, 9 AM to 5 PM CST, and replenishment ships from our IL, PA, GA or CA warehouses.
