Frequently Asked Questions

Who honestly needs 24,000 pages of toner in a single order?

A department that prints around 2,000 pages a month will work through this four-pack in about a year — one purchase covers the whole budget period. It also suits anyone standardizing several compatible printers on one shared cartridge, where a central stock of four serves the whole group. If your MS521dn prints a few hundred pages a month, this pack is more than you need and a two-pack is the smarter buy.

How does the four-pack pricing work out per cartridge?

Four singles would total $699.76; the four-pack is $644.30, which is $161.08 per cartridge and a saving of $55.46 over buying them one at a time. That is the lowest per-cartridge price in this standard-yield line. You are trading a larger single outlay for the best unit price and a year without reordering.

Is this listing only for the MS521dn?

The listing names the MS521dn, but the cartridges are the standard 56F1000 used right across the platform: MS321DN, MS421DN, MS421DW, MS521DN, MS621DN, MX321ADN, MX521ADE and MX521DE. A four-pack bought for one machine can supply any of those models, which is exactly why it works well as a shared departmental stock.

How should we rotate four cartridges so none sits too long?

Store the boxes sealed, flat, in a dry room-temperature cupboard, and write the arrival date on each box. Install the oldest box first — first in, first out — so the stock turns over evenly. Toner powder keeps well for years under those conditions, so a cartridge installed in month twelve performs like the one installed in month one.

Where does a bulk order like this ship from?

From the nearest of our four warehouses in Illinois, Pennsylvania, Georgia, and California. A four-pack is a single shipment, so the whole year's supply arrives together rather than dribbling in across separate orders. Questions about a bulk purchase are answered by our support team Monday through Friday, 9 AM to 5 PM CST.

What protection does a four-pack purchase carry?

The same as any smaller order here: a one-year warranty on every cartridge and free returns for a full year. If a unit from the pack misbehaves, it is handled individually under the process described on our shipping and returns page — you do not have to send the rest of the pack back.
